IO322: Configurable FPGA I/O Module

Configurable FPGA I/O module with Spartan 6 FPGA, analog and digital I/O, multi-gigabit transceivers, and Simulink driver blocks

Flexible and cost-effective configurable FPGA I/O module with your preferred set and channel count of FPGA code modules. Configurable at any time with the configuration implementation (CI) files provided by Speedgoat.

Selectable FPGA code module functionalities covered include PWM generation and capture, encoder measurement and simulation, high speed protocols including SPI, I2C, and UART (RS422/RS485), Cam and Crank measurement and simulation, and triggering and synchronization support. Spare digital I/O line can be used for general purpose digital on/off requirements.

Delivery of each configurable FPGA I/O module also includes a cable and terminal board for loopback testing and to quickly connect with your hardware. The I/O pin mapping for your selection of FPGA code modules is provided together with your custom configuration implementation file, and delivery of each FPGA code module includes Simulink driver blocks with configurable dialog fields and Simulink test models.

Digital I/O
Front I/O 48 x ESD protected front TTL I/O lines, 3.3/5V or ground, direction configurable by line. Maximum current: +/- 32mA
Rear I/O 64 x rear LCMOS, 3.3V or 32 LVDS, or a combination of it on P14
3 x Multi-Gigabit Transceivers on P16
Mean time between failures (MTBF)* 259,000 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.
