SAN JOSE, Calif., September 14, 2009 – Cypress Semiconductor Corp. (NYSE: CY) today announced two new architectures in its PSoC® programmable system-on-chip platform that dramatically increase performance and extend the world’s only programmable analog and digital embedded design platform delivering unmatched time-to-market, integration, and flexibility across 8-, 16-, and 32-bit applications. This new programmable analog and digital embedded design platform is powered by the revolutionary PSoC Creator™ Integrated Development Environment, which introduces a unique schematic-based design capture along with fully tested, pre-packaged analog and digital peripherals easily customizable through user-intuitive wizards and APIs to meet specific design requirements. PSoC Creator enables engineers to design the way they think and dramatically shorten time-to-market (see related release “PSoC Creator™ Software Delivers Revolutionary Design Environment For New Cypress PSoC 3 and PSoC 5 Architectures”). More information, including data sheets, application notes, online training, development kits, free PSoC Creator downloads and device samples, is available at

The unique programmable analog and digital peripherals in PSoC 3 and PSoC 5, along with new high performance 8-bit and 32-bit MCU sub-systems, enable new capabilities such as motor control, intelligent power supply and battery management, human interfaces such as CapSense® touch sensing, LCD segment display, graphics control, as well as audio/voice processing, communication protocols, and much more. These new capabilities dramatically expand the markets that PSoC can address, including industrial, medical, automotive, communications and consumer equipment. The total available market for PSoC products is now expanded to over fifteen billion dollars, spanning across 8-, 16- and 32-bit applications, as well as precision analog markets.

The new PSoC 3 and PSoC 5 architectures include high-precision, programmable analog resources that can be configured as ADCs, DACs, TIAs, Mixers, PGAs, OpAmps and more. They also include enhanced programmable-logic based digital resources that can be configured as 8-, 16-, 24- and 32-bit timers, counters, and PWMs, as well as more advanced digital peripherals such as Cyclic Redundancy Check (CRC), Pseudo Random Sequence (PRS) generators, and quadrature decoders. Designers have a unique ability to customize this digital system through full featured general purpose PLD-based logic available in PSoC 3 and PSoC 5.  The new architectures also support a wide range of communications interfaces, including Full-Speed USB, I2C, SPI, UART, CAN, LIN, and I2S.

The new PSoC 3 and PSoC 5 architectures are powered by high performance, industry-standard processors. The PSoC 3 architecture is based on a new, high-performance 8-bit 8051 processor with up to 33 MIPS, while the PSoC 5 architecture includes a powerful 32-bit ARM Cortex-M3 processor with up to 100 DMIPS. Both architectures meet the demands of extremely low power applications by delivering the industry’s widest voltage range from 5.5V down to 0.5V along with low 200nA hibernate current. They provide a seamless, programmable design platform from 8- to 32-bit architectures with pin and API compatibility between PSoC 3 and PSoC 5, along with programmable routing, allowing any signal, whether analog or digital, to be routed to any general-purpose I/O to ease circuit board layout. This capability includes the ability to route LCD Segment Display and CapSense signals to any GPIO pin.

“These new families, along with the revolutionary PSoC Creator Software, will change the way embedded designers solve problems,” said T.J. Rodgers, Cypress’s President and CEO. “The PSoC 3 and PSoC 5 architectures deliver a scalable platform with the computing power of high-performance MCUs, the precision of stand-alone analog devices and the flexibility of PLDs, all with a powerful, easy-to-use design environment. This combination gives designers of 8-, 16- and 32-bit applications the flexibility and integration of true ‘system-level’ programmability for the first time.”

“The PSoC is the only architecture that extends the concept of programmability beyond instructions for the processor to configuring peripherals and customization of digital functions,” said Tom Starnes, principal analyst at Objective Analysis in Austin, Texas. “Coupled with analog precision on-chip beyond that found in any other MCU, these highly-integrated PSoCs are more highly-programmable than any other chip. The addition of precision analog and the ARM Cortex processor to the family should bring the performance needed for any modern application.”

PSoC -- Because Change Happens
PSoC devices employ a highly configurable system-on-chip architecture for embedded control design, offering a flash-based equivalent of a field-programmable ASIC without lead-time or NRE penalties. PSoC devices integrate configurable analog and digital circuits, controlled by an on-chip microcontroller, providing both enhanced design revision capability and component count savings. A single PSoC device can integrate as many as 100 peripheral functions saving customers design time, board space and power consumption while improving system quality and reducing system cost.

The flexible PSoC resources allow designers to future-proof their products by enabling firmware-based changes during design, validation, production, and in the field. The unique PSoC flexibility shortens design cycle time and allows for late-breaking feature enhancements. All PSoC devices are also dynamically reconfigurable, enabling designers to morph internal resources on-the-fly, utilizing fewer components to perform a given task.
