Configurable I/O Module

The IO308 I/O module is a flexible, cost-effective and configurable Spartan®-6 FPGA providing 25k logic cells.

This I/O module features 32 RS422/485 differential I/O lines which can be individually programmed as inputs or outputs.

The IO308 I/O module comes with a Speedgoat configuration file offering a large selection of standard interfaces such as PWM and SPI.

Key Features

  • 32 RS422/485 differential I/O 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

Mean time between failures (MTBF)* 440,000 hours
MTBF (Mean Time Between Failure) - MTBF values shown are based on calculation according to MIL-HDBK-217F and MIL-HDBK-217F Notice 2. Environment: GB 20 °C. The MTBF calculation is based on component FIT rates provided by the component suppliers. If FIT rates are not available, MIL-HDBK-217F and MIL-HDBK-217F Notice 2 formulas are used for FIT rate calculation.
