Reconfigurable FPGA with 44-bit I/O
Using FET Switch Buffer
IndustryPack®
This is a single-width IP module with user configurable FPGA in the form of a Xilinx Spartan 3 FPGA XC3S200AN-5 with 200,000 system gates, and forty four channels of buffered digital input/output. The TI SN74CBT3245C FET bus switch is used to buffer the I/O lines allowing Bidirectional Data Flow, With Near-Zero Propagation Delay and Low ON-State Resistance (ron = 3ohms Typical) The 44 digital I/O lines can be individually programmed as inputs or outputs within the FPGA. Each I/O line has a resistor network which allows a selectable pull up/down voltage of GND, +3.3V or 5V). The unit also has an onboard 50MHz clock oscillator. The FPGA logic is configurable via JTAG plug on the IP card.
