  • Ordering Guide

GPIO-MM-21 is part of a family of reconfigurable digital I/O and counter / timer modules with various port and pin configurations. Each board uses identical hardware with a 200K gate Xilinx Spartan II RAM-based FPGA. The varying configurations are based on different FPGA code. The FPGA code is stored in a flash memory on the board, enabling GPIO-MM-21 to be reprogrammed in the field with different designs, including custom designs.

The GPIO-MM-21 configuration provides 96 digital I/O lines. 48 lines are buffered. The 96 digital I/O lines are compatible with our legacy GMM and OMM boards. This configuration combines the features of two 48-line digital I/O boards into one board to reduce your PC/104 stack size and cost.

Other GPIO-MM configurations provide 48 digital I/O lines with 10 16-bit counter/timers i.e. GPIO-MM-XT.
