The ispLSI 2064E is a High Density Programmable Logic Device. The device contains 64 Registers, 64 Universal I/O pins, four Dedicated Input Pins, three Dedicated Clock Input Pins, two dedicated Global OE input pins and a Global Routing Pool (GRP). The GRP provides complete interconnectivity between all of these elements. The ispLSI 2064E features 5V in-system programmability and in-system diagnostic capabilities. The ispLSI 2064E offers non-volatile reprogrammability of the logic, as well as the interconnect to provide truly reconfigurable systems.
