P104-GPIO96 is a PC/104-Plus general purpose digital I/O module integrating Diamond’s using a high-capacity PCI Express FPGA for maximum density and flexibility.

P104-GPIO96 is a programmable PC/104-Plus DIO module using a high-capacity (700K gate equivalent) PCI Express FPGA for maximum density and flexibility. The base hardware configuration features 96 digital I/O lines grouped into 12 8-bit ports. All ports have I/O buffers to protect the FPGA and feature 5V logic drive levels. The ports are organized into a combination of byte-wide, nibble-wide, and bit-wide direction control for maximum flexibility and application compatibility.

The built-in FPGA personality provides multiple configuration options. All 96 I/O lines may be used in common I/O mode; Six of these ports can be reconfigured to enable an array of additional features, including 8 32-bit up/down counter/timers with programmable input source and gate, 4 24-bit PWM circuits with 0-100% duty cycle capability and interrupt/latched mode operation.

The flash-based design enables easy field upgrades using a Diamond-provided software utility (no cable or third-party software required!) as well as custom code development. Universal Driver software support is included for Linux, Windows XP, Windows Embedded CE/Standard.
