LYNNWOOD, Wash., June 22, 2004 - Cypress MicroSystems Inc., a subsidiary of Cypress Semiconductor Corp.(NYSE: CY), today announced that it has shipped over 10 million Programmable System-on-Chip(TM)(PSoC(TM)) mixed-signal array devices to the embedded control market, demonstrating wide industry acceptance of this high-performance, cost-effective, mixed-signal integration platform. Cypress MicroSystems is currently shipping PSoC devices to hundreds of customers in Asia, Europe and the U.S., and over 1,000 new customers are actively designing with the PSoC family of devices.

"It's remarkable that PSoC has already shipped 10 million units so soon after its introduction," said Jerry Worchel, senior market analyst for InStat/MDR. "That is certainly testimony to the industry's recognition of the advantages of the highly-integrated PSoC mixed-signal architecture. Embedded designs traditionally consist of a microcontroller surrounded by scores of discrete analog and digital components. Cypress MicroSystems' customers are modernizing their embedded designs with a single PSoC array that absorbs the controller and most of the surrounding peripheral functionality. As more users discover the ease of design, manufacturing efficiencies and bill-of-materials savings that PSoC offers, I expect its acceptance to accelerate further."

Erik Wood, Marketing Product Manager, for Parallax Inc., of Rocklin, CA recently summarized his company's experience using PSoC in a motor controller application. "During development, our engineers compared the PSoC mixed signal array to silly putty' in describing its configurability-you can configure it in an almost infinite variety of ways. PSoC integrated 90 percent of the analog and digital components we would have typically used as discrete devices. Since the easily programmed PSoC family consists of many price-integrations points, it's simple to add or delete features to our base project going forward. Thanks to PSoC, our motor controller has more features and a lower price than similar products in our market place."

"When I ask our customers why they use PSoC, they tell me that its mixed-signal integration provides value across their company," said George Saul, President & CEO of Cypress MicroSystems. "Design engineers prefer simpler designs with fewer components; they also appreciate the faster development time that results from PSoC's automatically generated application program interfaces (APIs), interrupt service routines (ISRs) and the customer's final unique product data sheet. Purchasing professionals are attracted by the cheaper bill-of-materials as well as the benefit of sourcing and carrying fewer parts in inventory. Manufacturing engineers see value in the smaller printed circuit boards that PSoC enables and the improved system quality and reliability associated with fewer components to solder down. Finally, P&L managers appreciate the reusability and extensibility of the PSoC platform of products, which increases efficiency across the corporation."

About the PSoC Family

A true system-on-a-chip, PSoC devices are configurable mixed signal arrays that integrate the microcontroller and related peripheral circuits typically found in an embedded design. Employing easy to use development tools, designers select configurable, pre-characterized library elements to provide analog functions such as amplifiers, ADCs, DACs, filters and comparators and digital functions such as timers, counters, PWMs, SPI and UARTs. PSoC analog performance is instrumentation-quality - including rail-to-rail inputs, programmable gain, 14-bit ADCs and exceptionally low noise and input leakage and voltage offset.

In addition to these configurable analog and digital blocks, PSoC devices include a fast 8-bit microcontroller, up to 32KB of Flash memory, 2KB of SRAM, an 8x8 multiplier with 32-bit accumulator, power and sleep monitoring circuits, a precision real time clock and hardware I²C communications.

All PSoC devices are dynamically reconfigurable, enabling designers to create new system functions on-the-fly. Re-configuring the same silicon for different functions on different clock cycles, designers can achieve more than 120 percent utilization of the die in many cases. In the automotive PSoC LIN bus reference design, the same transistors are re-configured four times to support the different LIN communication modes; in doing so, these blocks consume less than 10 percent of PSoC hardware resources and less than 10 percent of the PSoC MCU cycles.

Software and Support

The software development environment, PSoC Designer 4.1 is a full-featured, GUI-based design tool suite that enables the user to configure their design in silicon with simple point and click options; code the MCU in either C or assembly language; and debug the design using sophisticated features such as event triggers and multiple break points while single-stepping through the code in C or assembly or a mix of the two.

The CY3205-DK Professional Class Development Kit includes a full-speed in-circuit emulator with a large trace buffer, which seamlessly integrates with PSoC Designer 4.1." The development kit includes everything necessary to complete a design with the PSoC family of ICs. The kits also contain all materials for the first four "Tele-training" classes offered on line by Cypress. The tools are designed to keep the cost of development to a minimum while providing all the features found in tools that cost $2,000 or more. The CY3205-DK is priced at $398.
