Configurable I/O module


The IO391 I/O module is a mini-PCIe-compatible, configurable I/O module with 50k logic cells, 26 ESD-protected TTL I/O lines and a Xilinx® Artix®-7 chip.  

All the I/O lines are individually programmable as input or output and can be set to high, low or tristate. 

Each TTL I/O line also has a pull resistor to a common programmable pull voltage that can be set to +3.3 V, +5 V and GND. 

The IO391 I/O module also has a basic heatsink to facilitate thermal management. The heatsink can be used to install additional cooling solutions like passive or active heatsinks or to provide a thermal connection to an enclosure. 

Key Features

  • 26x ESD-protected TTL I/O lines with pull resistors
  • Voltage levels of 3.3 V, 5 V, or ground, and input/output directions that are software configurable by I/O line
  • Configuration of the I/O module using Simulink blocks from the Speedgoat I/O Blockset library as part of the Simulink Real-Time™ workflow

Inter-module communication 8 MGT on XMC P16 Connector
Mean time between failures (MTBF)* 987,000 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 the FIT rate calculation.
