IO306: Digital and Configurable FPGA I/O Module

Configurable FPGA I/O module with digital I/O and Simulink® driver blocks


The IO306 I/O module is a flexible, cost-effective and configurable Spartan®-6 FPGA providing 25k logic cells.

This I/O module features 64 ESD-protected TTL lines which can be individually programmed as inputs or outputs. Each TTL I/O line also has a  pull resistor and the standard pull voltage level is fixed at +3.3 V. The IO306 I/O module comes with a Speedgoat FPGA configuration bitstream containing all of the required FPGA functionality.

Key Features

  • 64 ESD-protected TTL lines
  • Digital inputs and outputs
  • Configurable FPGA workflow for Simulink Real-Time™ supported by Speedgoat custom implementation bitstreams and the Speedgoat Library
  • Simulink Real-Time driver blocks for FPGA code modules
