Microchip Technology Incorporated

Overview of Our Business

Our Products

We develop and manufacture microcontrollers, application-specific standard
products, referred to as ASSPs, and related memory products for high-volume
embedded control applications. We market our products to the consumer,
automotive, office automation, communications and industrial markets.

We provide highly cost-effective embedded control products for a wide
variety of applications and believe that our PIC(R) product family is a
price/performance leader in the worldwide microcontroller market. Our embedded
control products also offer the advantages of small size, low voltage operation
and ease of development, enabling timely and cost-effective product integration
by our customers.

Our ASSP products include a variety of specialized integrated circuits,
including our family of KEELOQ(R) security products for wireless
communications.

Our memory products are primarily comprised of serial electrically erasable
programmable read-only memory, referred to as EEPROMs. Serial EEPROMs are used
primarily to provide non-volatile memory storage in embedded control systems.

Embedded control systems typically incorporate a microcontroller as the
principal active, and sometimes sole, component. A microcontroller is a self-
contained computer-on-a-chip consisting of a central processing unit, non-
volatile program memory, random access memory for data storage and various
input/output capabilities. In addition to the microcontroller, a complete
embedded control system incorporates application-specific software and may
include specialized peripheral device controllers and external non-volatile
memory components, such as EEPROMs to store additional program software.

Embedded control systems enable our customers to:

. differentiate their products

. replace less efficient electromechanical control devices

. add product functionality, and

. significantly reduce product cost.

Embedded control solutions have been incorporated into thousands of products
and subassemblies in a wide variety of markets worldwide, including:

. automotive air bag systems

. remote control devices

. handheld tools

. appliances

. portable computers

. cordless and cellular telephones

. motor controls, and

. security systems.

1


Our Strategy

Our strategy is to provide embedded control solutions that combine time-to-
market advantages with high performance and increased functionality. With our
field programmable microcontrollers and easy-to-use development systems,
customers can typically design and produce new products or new product features
in a few days. In addition, our reduced instruction set computing, referred to
as RISC, architecture provides faster performance than competing
microcontrollers. Using advanced design and manufacturing technology, we can
provide products that have some of the smallest package sizes and that operate
at voltage levels and power requirements that are among the lowest in the
embedded control industry.

Our Customers

We sell our products to a geographically diverse base of customers across a
broad and growing range of market applications, reducing our dependence on any
single industry, market or customer. We sell to more than 600 original
equipment manufacturer, referred to as OEM, customers directly. We also sell to
more than 20,000 other customers worldwide through our distributors. To date,
we have sold more than 160,000 application development systems, providing a
broad foundation for future microcontroller sales.

Our Manufacturing Capabilities

We design and fabricate wafers at our facilities in Chandler and Tempe,
Arizona. We continue to transition products to smaller geometries and to larger
wafer sizes to reduce future manufacturing costs. Our current manufacturing
geometries range from 0.7 to 1.2 microns, with all new products produced on the
smallest 0.7 micron process. We currently produce our products on 6-inch and 8-
inch wafers, with all incremental production on the larger 8-inch wafers.

The ownership of our manufacturing resources is an important component of
our business strategy, enabling us to maintain a high level of manufacturing
control and to be one of the lowest cost producers in the embedded control
industry. Direct control over wafer fabrication also enables us to shorten our
design and production cycles. We perform product packaging and testing at our
facilities located near Bangkok, Thailand. We also use third-party assembly and
test contractors in several Asian countries.

Our executive offices are located at 2355 West Chandler Boulevard, Chandler,
Arizona 85224-6199, and our telephone number is (480) 786-7200. Our web site
address is www.microchip.com. Information contained on our web site should not
be considered a part of this prospectus.

RISK FACTORS

An investment in our common stock involves a high degree of risk. You should
carefully consider the following factors before deciding to purchase shares of
our common stock. The trading price of our common stock could decline due to
any of these risks, in which case you could lose all or part of your
investment. In assessing these risks, you should also refer to the other
information in this prospectus, including our financial statements and the
related notes.

This prospectus contains forward-looking statements that involve risks and
uncertainties. We use words such as "anticipate," "believe," "plan," "expect,"
"future," "intend" and similar expressions to identify forward-looking
statements. Our actual results could differ materially from those anticipated
in the forward-looking statements as a result of certain factors, including the
risks described below and elsewhere in this prospectus. We disclaim any
obligation to update information contained in any forward-looking statement.

Our quarterly operating results may fluctuate due to factors that could reduce
our net sales and profitability.

Our quarterly operating results are affected by a wide variety of factors
that could reduce our net sales and profitability, many of which are beyond our
control. Some of the factors that may affect our operating results include:

. the level of orders that are received and can be shipped in a quarter

. market acceptance of both our products and our customers' products

. customer order patterns and seasonality

. availability of manufacturing capacity and fluctuations in manufacturing
yield

. the availability and cost of raw materials, equipment and other supplies,
and

. economic, political and other conditions in the worldwide markets served
by us.

We believe that period-to-period comparisons of our operating results are
not necessarily meaningful and that you should not rely upon any comparisons as
indications of future performance. In future periods our operating results may
fall below the expectations of public market analysts and investors, which
would likely have a negative effect on the price of our common stock.

If we fail to maintain manufacturing yields as we increase our capacity, we may
not be able to produce sufficient quantities of integrated circuits to meet
customer demand, which would harm our business.

The manufacture and assembly of integrated circuits, particularly non-
volatile, erasable memory and logic devices such as those that we produce, are
complex processes. These processes are sensitive to a wide variety of factors,
including the level of contaminants in the manufacturing environment,
impurities in the materials used and the performance of our fabrication
personnel and equipment. As is typical in the semiconductor industry, we have
from time to time experienced lower than anticipated manufacturing yields. Our
operating results will suffer if we are unable to maintain yields at
approximately current levels.

We believe that expansion of our manufacturing capacity is important to
enable us to respond to increased sales opportunities and maintain satisfactory
delivery schedules. Our business could suffer if the expansion of manufacturing
capacity is delayed or inefficiently implemented. Other companies in the
industry have experienced difficulty in expanding manufacturing capacity,
resulting in reduced yields or delays in product deliveries. We may experience
manufacturing yield or delivery problems in the future, which could harm our
operating results.

4

We depend on orders that are received and shipped in the same quarter and
therefore have limited visibility of future product shipments.

Our net sales in any given quarter depend upon a combination of orders
received in that quarter for shipment in that quarter, which we refer to as
turns orders, and shipments from backlog. If we do not achieve a sufficient
level of turns orders in a particular quarter, our net sales and operating
results will suffer. We have emphasized our ability to respond quickly to
customer orders as part of our competitive strategy. From fiscal 1994 through
fiscal 1999, this strategy resulted in customers placing orders with
increasingly shorter delivery schedules. This had the effect of increasing
turns orders as a portion of our business in any given quarter and reducing our
visibility on future product shipments. The percentage of turns orders has
decreased substantially for the first three quarters of fiscal 2000, but may
return to higher levels in the future. Because turns orders are difficult to
predict, increased levels of turns orders make our net sales more difficult to
predict.

Intense competition in our markets may lead to reduced sales of our products
and reduced market share.

The semiconductor industry is intensely competitive and has been
characterized by price erosion and rapid technological change. We compete with
major domestic and international semiconductor companies, many of which have
greater market recognition and substantially greater financial, technical,
marketing, distribution and other resources than we with which to pursue
engineering, manufacturing, marketing and distribution of their products.
Emerging companies are also increasing their participation in the market for
embedded control applications. In addition, our ability to compete successfully
depends on a number of factors both within and outside our control, including:

. the quality, performance, reliability, features, ease of use, pricing and
diversity of our products

. the quality of our customer services and our ability to address the needs
of our customers

. our success in designing and manufacturing new products including those
implementing new technologies

. efficiency of production

. the rate at which customers incorporate our products into their own
products

. product introductions by our competitors, and

. protection of our products and processes by effective utilization of
intellectual property laws.

Historically, average selling prices in the semiconductor industry decrease
over the life of any particular product. The overall average selling prices of
our microcontroller products have remained relatively constant, while average
selling prices of our memory products have declined over time. We have
experienced, and expect to continue to experience, pricing pressure in certain
microcontroller product lines, due primarily to competitive conditions. We may
be unable to maintain average selling prices for our microcontroller or other
products as a result of increased pricing pressure in the future. An increase
in pricing pressure could force us to reduce our average selling prices, which
would reduce our operating results.

We may be unable to compete successfully in the future, which could harm our
business.

We may lose sales if our suppliers of raw materials and equipment fail to meet
our needs.

Our semiconductor manufacturing operations require raw materials and
equipment that must meet exacting standards. We generally have more than one
source for these supplies, but there are only a limited number of suppliers
capable of delivering various raw materials and equipment that meet our
standards. In addition, the raw materials and equipment necessary for our
business could become more difficult to obtain as worldwide use of
semiconductors increases. An interruption of any raw materials or equipment
sources could harm our business. We have faced supply shortages from time to
time in the past, and on occasion our suppliers have told us they need more
time than expected to fill our orders.

5

Our business is highly dependent on selling through distributors.

Distributors accounted for 63% of our net sales to customers for the nine
months ended December 31, 1999. Our largest distributor accounted for 14% of
our total net sales for the nine months ended December 31, 1999. Generally, we
do not have long-term agreements with our distributors and our distributors may
terminate their relationship with us with little or no advanced notice.

The loss of, or a disruption in the operations of, one or more of our
distributors could reduce our net sales in a given quarter and could result in
an increase in inventory returns.

Our operating results may be impacted by the wide fluctuations of supply and
demand in the semiconductor industry.

The semiconductor industry has been characterized by wide fluctuations of
supply and demand. The industry has experienced significant economic downturns
at various times, characterized by diminished product demand, accelerated
erosion of average selling prices and production over-capacity. We have sought
to reduce our exposure to industry cyclicality by selling products to a
geographically diverse base of customers across a broad range of market
applications. However, we may experience substantial period-to-period
fluctuations in future operating results due to general industry or economic
conditions.

If we are unable to adequately protect or enforce our intellectual property
rights, we could lose market share, incur costly litigation expenses or lose
valuable assets.

Our success depends in part on our ability to obtain patents, licenses and
other intellectual property rights covering our products and manufacturing
processes. To that end, we have acquired certain patents and patent licenses
and intend to continue to seek patents on our inventions and manufacturing
processes. The process of seeking patent protection can be long and expensive,
and patents may not be issued from currently pending or future applications. In
addition, our existing patents and any new patents that are issued may not be
of sufficient scope or strength to provide meaningful protection or any
commercial advantage to us. We may be subject to or may initiate interference
proceedings in the U.S. Patent and Trademark Office, which can require
significant financial and management resources. In addition, the laws of
certain foreign countries do not protect our intellectual property rights to
the same extent as the laws of the United States.

As is typical in the semiconductor industry, we have from time to time
received, and may in the future receive, communications alleging possible
infringement of patents or other intellectual property rights of others. We
investigate all infringement notices and respond as we believe is appropriate.
Based on industry practice, we believe that in most cases we can obtain any
necessary licenses or other rights on commercially reasonable terms, but we
cannot assure that licenses would be available on acceptable terms, that
litigation would not ensue or that damages for any past infringement would not
be assessed. Litigation, which could result in substantial cost to us and
diversion of management effort, may be necessary to enforce our patents or
other intellectual property rights or to defend us against claimed infringement
of the rights of others. The failure to obtain necessary licenses or other
rights or litigation arising out of infringement claims could harm our
business.

We are highly dependent on foreign sales and operations, which exposes us to
foreign political and economic risks.

Sales to foreign customers account for a substantial portion of our net
sales. During the nine months ended December 31, 1999, 68% of our net sales
were made to foreign customers. We purchase a substantial portion of our raw
materials and equipment from foreign suppliers. In addition, we own product
packaging and testing facilities located near Bangkok, Thailand. We also use
various third-party contractors located throughout Asia for a portion of our
packaging and testing requirements.

6

Our reliance on foreign sales and operations exposes us to foreign
political and economic risks, including:

. political, social and economic instability

. trade restrictions and changes in tariffs

. import and export license requirements and restrictions

. difficulties in staffing and managing international operations

. disruptions in international transport or delivery

. fluctuations in currency exchange rates

. difficulties in collecting receivables, and

. potentially adverse tax consequences.

If any of these risks materialize, our foreign sales could decrease and our
foreign operations could suffer.

Various Asian countries recently experienced significant economic
difficulties. These difficulties included business failures and a generally
depressed business climate, particularly in the semiconductor industry.
Because of our reliance on Asian facilities, any further economic crisis in
Asia may harm our business.

We are subject to stringent environmental regulation, which may force us to
incur significant expenses.

We must comply with many different federal, state and local governmental
regulations related to the use, storage, discharge and disposal of toxic,
volatile or otherwise hazardous chemicals used in our manufacturing process.
Although we believe that our activities conform to presently applicable
environmental regulations, our failure to comply with present or future
regulations could result in the imposition of fines, suspension of production
or a cessation of operation. Any regulation could require us to acquire costly
equipment or to incur other significant expenses to comply with environmental
regulations. Any failure by us to control the use of or adequately restrict
the discharge of hazardous substances could subject us to future liabilities.
Environmental problems may occur that could subject us to future costs or
liabilities.

We must attract and retain qualified personnel to be successful, and
competition for qualified personnel is intense in our market.

Our success depends to a significant extent upon the efforts and abilities
of our senior management, engineering and other personnel. The competition for
qualified engineering and management personnel is intense. We may be
unsuccessful in retaining our existing key personnel or in attracting and
retaining additional key personnel that we require. The loss of the services
of one or more of our key personnel or the inability to add key personnel
could harm our business. We have no employment agreements with any member of
our senior management team.

The year 2000 problem may adversely affect us by causing failures in our
internal systems or in systems used by our suppliers, distributors or
customers.

The year 2000 problem is the potential for system and processing failure of
date-related data as a result of computer-controlled systems that use two
digits rather than four to define a year in the date field. Many computer
hardware systems and software applications could fail or create erroneous
results unless corrected so that they can correctly process data related to
the year 2000 and beyond. Failures by our internal systems, or by systems used
by our suppliers, distributors or customers, could seriously harm our
business. In particular, the infrastructure of foreign countries where our
products are manufactured or our customers are located may be subject to
disruption or failure as a result of the year 2000 problem.

7

The future trading price of our common stock could be subject to wide
fluctuations in response to a variety of factors.

The market price of our common stock has fluctuated significantly in the
past and is likely to fluctuate in the future. The future trading price of our
common stock could be subject to wide fluctuations in response to a variety of
factors, many of which are beyond our control, including:

. quarterly variations in our operating results and the operating results
of other semiconductor companies

. actual or anticipated announcements of technical innovations or new
products by us or our competitors

. changes in analysts' estimates of our financial performance or buy/sell
recommendations

. general conditions in the semiconductor industry, and

. worldwide economic and financial conditions.

In addition, the stock market has experienced significant price and volume
fluctuations that have particularly affected the market prices for many high
technology companies and that often have been unrelated to the operating
performance of such companies. These broad market fluctuations and other
factors may harm the market price of our common stock.

Provisions in our charter may have anti-takeover effects.

Provisions in our certificate of incorporation allow us to issue preferred
stock with voting, liquidation and dividend rights senior to those of our
common stock without the approval of our stockholders. The issuance of
preferred stock, while providing desirable flexibility in connection with
possible acquisitions or other corporate purposes, could have the effect of
making it more difficult for a third party to acquire a majority of our
outstanding stock. We have no present plans to issue shares of preferred stock.

DIVIDEND POLICY

We have not paid any cash dividends since our inception. We currently
anticipate that we will retain all of our future earnings for use in the
expansion and operation of our business. Thus, we do not anticipate paying any
cash dividends on our capital stock in the foreseeable future.

USE OF PROCEEDS

The net proceeds to us from the sale of the 1,650,000 shares being offered
under this prospectus at a price per share of $63.50 will be approximately
$99,136,250, or $114,066,688 if the underwriters' over-allotment option is
exercised in full, after deducting the underwriter discounts and commissions
and estimated expenses payable by us in connection with the offering. We intend
to use the net proceeds to purchase additional wafer fabrication and final test
equipment and to fund the construction of additional office building space.
Pending these uses, we intend to invest the net proceeds in investment grade,
interest bearing securities.

UNDERWRITING

Under the terms and subject to the conditions contained in an underwriting
agreement dated March 23, 2000, we have agreed to sell to the underwriters
named below, for whom Credit Suisse First Boston Corporation, Merrill Lynch,
Pierce, Fenner & Smith Incorporated, Prudential Securities Incorporated and
FleetBoston Robertson Stephens Inc. are acting as representatives, the
following respective numbers of shares of common stock:

=========


The underwriting agreement provides that the underwriters are obligated to
purchase all of the shares of common stock in the offering if any are
purchased, other than those shares covered by the over-allotment option
described below. The underwriting agreement also provides that if an
underwriter defaults, the purchase commitments of the non-defaulting
underwriters may be increased or the offering of common stock may be
terminated.

We have granted to the underwriters a 30-day option to purchase on a pro-
rata basis up to 247,500 additional shares at the public offering price less
the underwriting discounts and commissions. The option may be exercised only to
cover any over-allotments of common stock.

The underwriters propose to offer the shares of common stock initially at
the public offering price on the cover page of this prospectus and to selling
group members at that price less a concession of $1.905 per share. The
underwriters and selling group members may allow a discount of $0.10 per share
on sales to other broker/dealers. After the public offering of the common
stock, the public offering price and concession and discount to broker/dealers
may be changed by the underwriters.

The following table summarizes the compensation and estimated expenses we
will pay:

Expenses payable by us.......... $ .242 $ .211 $ 400,000 $ 400,000


We and our directors and executive officers have agreed that we and they
will not offer, sell, contract to sell, pledge or otherwise dispose of,
directly or indirectly, any shares of our common stock or securities
convertible into or exchangeable or exercisable for any shares of our common
stock, or enter into a transaction which would have the same effect or publicly
disclose the intention to make any such offer, sale, pledge or disposal without
the prior written consent of Credit Suisse First Boston Corporation for a
period of 90 days after the date of this prospectus, except that our executive
officers and directors may collectively sell up to 375,000 shares of our common
stock in the open market without regard to the restrictions described in this
paragraph.

We have agreed to indemnify the underwriters against liabilities under the
Securities Act or contribute to payments which the underwriters may be required
to make in that respect.

Our common stock is listed on The Nasdaq National Market under the symbol
MCHP.

The representatives may engage in over-allotment, stabilizing transactions,
syndicate covering transactions, penalty bids and "passive" market making in
accordance with Regulation M under the Securities Exchange Act of 1934.

. Over-allotment involves syndicate sales in excess of the offering size,
which creates a syndicate short position.

. Stabilizing transactions permit bids to purchase the underlying security
so long as the stabilizing bids do not exceed a specified maximum.

. Syndicate covering transactions involve purchases of the shares of the
common stock in the open market after the distribution has been completed
in order to cover syndicate short positions.

. Penalty bids permit the underwriters to reclaim a selling concession from
a syndicate member when the shares of common stock originally sold by
that syndicate member is purchased in a syndicate covering transaction to
cover syndicate short positions.

. In "passive" market making, market makers in the common stock who are
underwriters or prospective underwriters may, subject to specific
limitations, make bids for or purchases of the common stock until the
time, if any, at which a stabilizing bid is made.

These stabilizing transactions, syndicate covering transactions and penalty
bids may cause the price of the common stock to be higher than it would
otherwise be in the absence of these transactions. These transactions may be
effected on The Nasdaq National Market or otherwise and, if commenced, may be
discontinued at any time.

A prospectus in electronic format will be made available on the websites
maintained by one or more of the underwriters participating in this offering.
The representatives may agree to allocate a number of shares to underwriters
for sale to their online brokerage account holders. Internet distributions will
be allocated by the underwriters that will make internet distributions on the
same basis as other allocations.

Other than the prospectus in electronic format, the information contained on
any underwriter's website and any information contained on any other website
maintained by an underwrite is not part of this prospectus or the registration
statement of which this prospectus forms a part, has not been approved or
endorsed by us or any underwriter in its capacity as an underwriter and should
not be relied upon by investors.

NOTICE TO CANADIAN RESIDENTS

Resale Restrictions

The distribution of the common stock in Canada is being made only on a
private placement basis exempt from the requirement that we prepare and file a
prospectus with the securities regulatory authorities in each province where
trades of common stock are effected. Accordingly, any resale of the common
stock in Canada must be made in accordance with applicable securities laws
which will vary depending on the relevant jurisdiction, and which may require
resales to be made in accordance with available statutory exemptions or
pursuant to a discretionary exemption granted by the applicable Canadian
securities regulatory authority. Purchasers are advised to seek legal advice
prior to any resale of the common stock.

Representations of Purchasers

Each purchaser of common stock in Canada who receives a purchase
confirmation will be deemed to represent to us and the dealer from whom such
purchase confirmation is received that (i) such purchaser is entitled under
applicable provincial securities laws to purchase such common stock without the
benefit of a prospectus qualified under such securities laws, (ii) where
required by law, that such purchaser is purchasing as principal and not as
agent, and (iii) such purchaser has reviewed the text above under "Resale
Restrictions".

Rights of Actions (Ontario Purchasers)

The securities being offered are those of a foreign issuer and Ontario
purchasers will not receive the contractual right of action prescribed by
Ontario securities law. As a result, Ontario purchasers must rely on other
remedies that may be available, including common law rights of action for
damages or rescission or rights of action under the civil liability provisions
of the U.S. federal securities laws.

Enforcement of Legal Rights

All of the issuer's directors and officers as well as the experts named
herein may be located outside of Canada and, as a result, it may not be
possible for Canadian purchasers to effect service of process within Canada
upon the issuer or such persons. All or a substantial portion of the assets of
the issuer and such persons may be located outside of Canada and, as a result,
it may not be possible to satisfy a judgment against the issuer or such persons
in Canada or to enforce a judgment obtained in Canadian courts against such
issuer or persons outside of Canada.

Notice to British Columbia Residents

A purchaser of common stock to whom the Securities Act (British Columbia)
applies is advised that such purchaser is required to file with the British
Columbia Securities Commission a report within ten days of the sale of any
common stock acquired by such purchaser pursuant to this offering. Such report
must be in the form attached to British Columbia Securities Commission Blanket
Order BOR #95/17, a copy of which may be obtained from us. Only one such report
must be filed in respect of common stock acquired on the same date and under
the same prospectus exemption.

Taxation and Eligibility for Investment

Canadian purchasers of common stock should consult their own legal and tax
advisors with respect to the tax consequences of an investment in the common
stock in their particular circumstances and with respect to the eligibility of
the common stock for investment by the purchaser under relevant Canadian
legislation.
