TE0320 (Spartan-3A DSP) Industrial Micromodule Series

Trenz Electronic TE0320

The TE0320 is an industrial-grade FPGA micromodule integrating a leading-edge Xilinx Spartan-3A DSP FPGA, a USB 2.0 microcontroller, 32-bit wide 128 MByte DDR RAM, 4 MByte Flash memory for configuration and operation, and powerful switch-mode power supplies for all on-board voltages. A large number of configurable I/Os is provided via robust board-to-board (B2B) connectors.

All this on a tiny footprint, smaller than a credit card, at the most competitive price.

Free and open reference designs are available for download in our download area.
