uC/OS-III and Micrium Cortex-M3 Combine with PSoC 5 To Deliver Powerful, Flexible Designs for Embedded Applications


SAN JOSE, Calif., November 29, 2010 - Cypress Semiconductor Corp. (Nasdaq: CY) and Micrium, Inc. (Weston, FL) today announced that Micrium's uC/OS-III RTOS (Real-Time Operating System) supports Cypress’s PSoC® 5 development platform.


The unique programmable analog and digital peripherals in PSoC 5, along with the high performance 32-bit Arm® Cortex™-M3 processor, position PSoC 5 for demanding applications such as industrial, medical, automotive, and consumer equipment. PSoC 5 devices offer industry-leading integrated analog resources and powerful, PLD-based Universal Digital Blocks for implementing standard and custom digital peripherals.

Micrium's middleware, long appreciated for its rapid-time-to market focus, is ideal for the Arm® Cortex™-M3 based 32-bit applications targeted by the PSoC 5 Cortex-M3 platform. All three technologies complement each other, providing the embedded engineer with a cadre of development tools, M3 debug capabilities, fast-time-to prototype, ease of use, and more. By adding analog components in a programmable fabric, the result is reduced complexity and the ability to make changes easily in the field.

"For years, it was difficult to combine analog circuitry and digital components. The PSoC 5 platform offers a very simple yet powerful building-block approach to adding analog,” said Jean Labrosse, president and CEO of Micrium. "Combined with the Arm Cortex-M3 processor, it opens up a wealth of new designs in industrial, medical, automotive and consumer embedded applications where Micrium has considerable experience. Micrium's expertise with the Cortex M3 processor and our strong education and support capabilities offer rapid time-to-market and ease-of-implementation advantages to PSoC 5 users targeting the embedded space,"

Micrium’s uC/OS-II and uC/OS-III are fully featured kernels designed specifically to address the requirements of embedded systems.  Both kernels have been running on Arm cores for years and are especially well-suited for the Cortex-M processor family.  The uC/OS-III port for the Cortex-M family uses assembly language optimizations to achieve maximum efficiency in frequently executed kernel functions.

uC/OS-II and uC/OS-III can each be used alone or in conjunction with other best-in-class software components from Micrium’s product line-up.  Micrium’s flexible model allows developers to easily combine components into a robust software platform for PSoC 5 projects.
