Connect Tech FreeForm/104 - FPGA with High Speed Digital I/O

Xilinx Spartan 3E FPGA with 500,000 Gates and 360K RAM

Introduction

FreeForm/104 is a PC/104 based FPGA development board for digital I/O and control applications.

Based on Xilinx’s Spartan-3E, Connect Tech’s FreeForm/104 provides off-the-shelf flexibility, making it ideal for high speed, compute-intensive, reconfigurable applications. The FPGA configuration is stored in flash memory, allowing users to easily implement design changes during development or in the field.

Customized FPGA configurations can be developed easily by the user with the free Xilinx ISE WebPACK software, or through Connect Tech’s engineering services.

The versatility and high speed processing core of the FreeForm/104 makes it ideal for applications including; DSP, software defined radio, aerospace, defense systems, computer hardware emulation, production or laboratory testing and industrial process monitoring and control.
