DSP Evaluation Board drives motors and control systems.

Press Release Summary:

Model GAO 2812EVM-II TI DSP Evaluation Board comes with on-board TMS320F2812 DSP and 32-bit fix-point Flash DSP operating at 150 MHz. Using independent power supply for A/D sampling, it avoids EMI from CPU core, and has NE2000 compatible 10M Ethernet interface. Unit features 128 K 16-bits on-chip Flash program memory, 18 K 16-bits on-chip SRAM, 256 K 16-bits extended SRAM, 512 K 16-bits extended SRAM as program/data RAM, 4 K 16 BOOT ROM, and 1 K 16 OTP ROM on-chip.

Original Press Release:

GAO Embedded Rolls out Update for TI DSP Evaluation Board - GAO 2812EVM - II


Toronto, ON, Jan. 2008 - GAO Embedded Inc. has introduced an upgrade to its TI Evaluation board. The newly developed board, GAO 2812EVM-II, is specially optimized for driving motors and control systems that are based on TMS320F2812 series DSPs. In addition, it uses an independent power supply for AD sampling thus avoiding EMI from the CPU core.

The new features and improvements to the GAO 2812EVM-II will aid rapid development. Further more, it can even be used as a control unit in a system.

Features include:
o On-board TMS320F2812 DSP, 32-bit fix-point Flash DSP, operating at 150Mhz
