Industry Background

Competitive pressures require manufacturers of a wide variety of products to expand product functionality and provide differentiation while maintaining or reducing cost. To address these requirements, manufacturers often use integrated circuit-based embedded control systems that enable them to:

·differentiate their products

·replace less efficient electromechanical control devices

·reduce the number of components in their system

·add product functionality

·decrease time to market for their products

·significantly reduce product cost

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

·automotive comfort, safety and entertainment applications

·remote control devices

·handheld tools

·home appliances

·portable computers

·robotics

·accessories

·cordless and cellular telephones

·motor controls

·security systems

·educational and entertainment devices

·consumer electronics

·power supplies

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 peripheral capabilities. In addition to the microcontroller, a complete embedded control system incorporates application-specific software and may include specialized peripheral device controllers, non-volatile memory components such as EEPROMs, and various analog and interface products.

The increasing demand for embedded control has made the market for microcontrollers one of the larger segments of the semiconductor market at approximately $14 billion in calendar year 2008. Microcontrollers are currently available in 4-bit through 32-bit architectures. 4-bit microcontrollers are the smallest segment of the microcontroller market and have been in decline for several years. 8-bit microcontrollers remain very cost-effective for a wide range of high volume embedded control applications and, as a result, continue to represent the largest portion of the overall microcontroller market. 16-bit and 32-bit microcontrollers provide higher performance and functionality, and are generally found in more complex embedded control applications.

Our Products

Our strategic focus is on embedded control solutions, including:

·microcontrollers

·development tools

·analog and interface products

·memory products

We provide highly cost-effective embedded control solutions that also offer the advantages of small size, high performance, low voltage/power operation and ease of development, enabling timely and cost-effective embedded control product integration by our customers.

Microcontrollers

We offer a broad family of microcontroller products featuring our unique, proprietary architecture marketed under the PIC brand name. We believe that our PIC product family is a price/performance leader in the worldwide microcontroller market. We have shipped over 7 billion PIC microcontrollers to customers worldwide since their introduction in 1990. Our PIC products are designed for applications requiring field programmability, high performance, low power and cost effectiveness. They feature a variety of memory technology configurations, low voltage and power, small footprint and ease of use. Our performance results from a product architecture which features dual data and instruction pathways, referred to as a Harvard dual-bus architecture; a Reduced Instruction Set Computer, referred to as RISC; and variable length instructions; all of which provide significant speed advantages over alternative single-bus, Complex Instruction Set Computer architectures, referred to as CISC. With approximately 600 microcontrollers in our product portfolio, we target the 8-bit, 16-bit, and 32-bit microcontroller markets.

Digital Signal Controllers (DSC) are a subset of our 16-bit microcontroller offering. Our dsPIC Digital Signal Controller families integrate the control features of high-performance 16-bit microcontrollers with the computation capabilities of Digital Signal Processors (DSPs), along with a wide variety of peripheral functions making them suitable for a large number of embedded control applications. Our dsPIC product family offers a broad suite of hardware and software development tools, software application libraries, development boards and reference designs to ease and expedite the customer application development cycle. With its field-re-programmability, large selection of peripheral functions, small footprint and ease of use, we believe that our dsPIC Digital Signal Controllers enlarge our addressable market.

We have used our manufacturing experience and design and process technology to bring additional enhancements and manufacturing efficiencies to the development and production of our PIC family of microcontroller products. Our extensive experience base has enabled us to develop our advanced, low-cost user programmability feature by incorporating non-volatile memory, such as Flash, EEPROM and EPROM Memory, into the microcontroller, and to be a leader in reprogrammable microcontroller product offerings.

Development Tools

We offer a comprehensive set of low-cost and easy-to-learn application development tools. These tools enable system designers to quickly and easily program a PIC microcontroller and dsPIC Digital Signal Controllers for specific applications and, we believe are a key factor for obtaining design wins.

Our family of development tools for PIC and dsPIC devices operates in the standard Windows® environment on standard PC hardware. These tools range from entry-level systems, which include an assembler and programmer or in-circuit debugging hardware, to fully configured systems that provide in-circuit emulation hardware. Customers moving from entry-level designs to those requiring real-time emulation are able to preserve their investment in learning and tools as they migrate to future PIC devices since all of our PIC and dsPIC development tools share the same integrated development environment.

Many independent companies also develop and market application development tools that support our standard microcontroller product architecture. Currently, there are approximately 200 third-party tool suppliers worldwide whose products support our proprietary microcontroller architecture.

We believe that familiarity with and adoption of both our and third-party development tools by an increasing number of product designers will be an important factor in the future selection of our embedded control products. These development tools allow design engineers to develop thousands of application-specific products from our standard microcontrollers. To date, we have shipped more than 750,000 development tools.

Analog and Interface Products

Our analog and interface products consist of several families with over 550 power management, linear, mixed-signal, thermal management and interface products. At the end of fiscal 2009, our mixed-signal analog and interface products were being shipped to more than 13,100 end customers.

We continue marketing and selling our analog and interface products into our existing microcontroller customer base, which we refer to as our analog “attach” strategy, as well as to new customers. In addition to our “attach” strategy, we market and sell other products that may not fit our traditional PIC microcontroller and memory products customer base. We market these, and all of our products, based on an application segment approach targeted to provide customers with application solutions.

Memory Products

Our memory products consist primarily of serial electrically erasable programmable read-only memory, referred to as Serial EEPROMs. We sell these devices primarily into the embedded control market, and we are one of the largest suppliers of such devices worldwide. Serial EEPROM products are used for non-volatile program and data storage in systems where such data must be either modified frequently or retained for long periods. Serial EEPROMs have a very low I/O pin requirement, permitting production of very small devices.

Employees

As of March 31, 2009, we had 4,895 employees. None of our employees are represented by a labor organization. We have never had a work stoppage and believe that our employee relations are good.
