Cypress Semiconductor Corp. announced that its PSoC 3 Programmable Embedded System-on-chip has been adopted by AVnet in its low-power Xilinx Spartan-6 LX16 FPGA Evaluation Kit, claimed by AVnet to be the industry's first-ever battery-powered Xilinx FPGA development board.

The PSoC 3 device executes power management, CapSense touch-sensing, USB/UART/SPI connectivity and configuration of the Field Programmable Gate Array (FPGA) directly on the board. Texas Instruments provides the battery management devices and power regulation circuitry. TI's load switches selectively power only those circuits immediately necessary. The Spartan-6 consumes up to 60 percent less power than the Spartan-3A.

Moreover, flexible PSoC 3 I/Os also allow the board to interface to the "analog world" through an expansion connector which accepts an included Avnet LCD board, user prototype boards and various Cypress expansion boards available from Avnet Electronics Marketing.

As seen at the Avnet Electronics Marketing and Xilinx x-Fest training events, the PSoC 3 device actively reconfigures its 20-bit Delta Sigma Analog-to-Digital Converter to execute precision voltage-monitoring and current-monitoring on 1.2V, 1.8V and 3.3V power supply rails. PSoC 3 digital resources handles complex power-on sequencing and sleep modes for the board, which is powered by a lithium-ion battery, a USB cable connection or a 12V adaptor.

VP of worldwide distribution for Cypress, Geoff Charubin says, "Avnet's Spartan-6 LX16 FPGA Evaluation board uses the PSoC platform to deliver analog-intensive sensing, power management and user interface capabilities for a wide range of applications." He explains that today's design engineers are eager for ways to quickly ramp up development with new technologies such as the Xilinx Spartan-6 family.

These programmable digital resources also permit direct serial configuration of the FPGA, and SPI, I2C and UART interfaces throughout the board. The evaluation kit allows users to build multiple PSoC 3 user interface functions with 4 CapSense touch-sensing buttons, an integrated USB UART bridge to a host PC and a large segment LCD expansion board, as well.

Users may program and debug the PSoC 3 device on the board with the CY8CKIT-002psoC MiniProg3 Program and Debug Kit (sells for US$89).
