I/O Interface Extension

The IO3XX-21 is a Speedgoat I/O interface extension and can be used to expand the functionality of Simulink-Programmable FPGA I/O modules and Configurable I/O modules with 56 single-ended digital lines. This I/O interface extension requires an additional slot in your test system.

The pull resistor is software configurable and can either be a 3.3V pull-up, 5V pull-up, or pull-down to ground. The direction of the seven groups of eight digital lines can be configured as input or output by software.

The IO3XX-21 I/O interface extension can support up to three I2C master implementations. I2C Slave support is available on request.

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 unavailable, MIL-HDBK-217F and MIL-HDBK-217F Notice 2 formulas are used for the FIT rate calculation.
