– 96 programmable digital I/O lines based on 8255 cores
– 3 pin headers for a total of 100 I/O pins
– Based on a Xilinx Spartan II RAM-based FPGA for field reconfigurability FPGA personality display for easy identification
– -40 to +85°C operation
– PC/104 form factor
– FREE Universal Driver software included
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 Garnet-MM and Onyx-MM 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.
Digital I/O Features
The digital I/O includes 96 programmable-direction lines using four 8255 cores. 48 of the I/O lines are buffered for enhanced output current. All I/O lines contain jumper-selectable 10Kohm pull-up/pull-down resistors. 48 I/O lines are contained on each of two 50-pin connectors, along with system ground and a convenient +5V power pin. Both I/O connectors provide the digital I/O lines in ABC port order.
The board requires only a +5V input and operates from -40°C to +85°C. All board functions are supported by our Universal Driver software for Linux, Windows 98/2000/XP/CE.NET, DOS, QNX, and VxWorks.
