The IO3xx-24 is a Speedgoat rear plug-in. It is ideally suited for electric motor control applications as it can interface control algorithms to multiple position sensors and power-converted gate drives.

The IO3xx-24 is used to expand the I/O functionality of Simulink-programmable FPGA I/O modules and configurable I/O modules with 2 independent resolver measurement channels. Each resolver-to-digital converter channel includes a reference signal oscillator. The plug-in features up to 40 single-ended and up to 8 differential digital I/O lines.

The digital I/O lines have software-programmable transceiver voltage, pull-resistor and termination resistor settings. The pull resistor is software configurable and can either be 3.3 V pull-up, 5 V pull-up or pull-down to ground. The direction of the five groups of eight single-ended digital lines can be software configured as input or output. Up to 16 single-ended digital lines can be configured to work as up to 8 differential digital lines. Differential I/O lines can be used as bi-directional interfaces with output-enable ports.

Using a Simulink-Programmable FPGA module, you can precisely sample and read the position, speed and fault registers of the resolver-to-digital converter. You can also directly access all digital I/O lines. All interfaces are included in the IO3xx HDL Coder Integration Package.

Using a Configurable I/O module, you can access the resolver-to-digital converter using a fully integrated driver block. The digital I/O lines can be mapped to a variety of functionalities such as PWM, Quadrature Decoder or serial communication interfaces based on a custom FPGA configuration file.

Reliability
Mean time between failures (MTBF)*	930,000 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.
