GPIO-MM FAMILY DIGITAL I/O AND COUNTER / TIMER • Multiple configurations and pin definitions • Up to 96 digital I/O pins with programmable direction • Up to 10 16-bit counter / timers with a 40MHz clock with 8 fixed digital inputs and 8 fixed outputs • EEPROM storage of address / interrupt configuration for automatic power-on configuration • 3 pin headers for a total of 100 I/O pins DESCRIPTION The GPIO-MM Family consists of a set of 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. Base hardware supports up to 96 digital I/O pins with programmable direction based on 8255 cores and up to 10 16-bit counter / timers based on 9513 cores. Up to 100 I/O pins are provided by the module including four fixed digital outputs. 48 of the 100 I/O pins are buffered. The three configurations currently offered include one configuration with 96 programmable digital I/Os and no counter / timers. The other two configurations provide 48 buffered digital I/O pins and 10 16-bit counter / timers. These two configurations differ in pin out definition to provide compatibility with two predecessor Diamond Systems products. The board requires only a +5V input and operates from -40°C to +85°C.
