描述 Description

The ispLSI and pLSI 1032E are High Density Programmable Logic Devices containing 192 Registers, 64 Universal I/O pins, eight Dedicated Input pins, four Dedicated Clock Input pins and a Global Routing Pool (GRP). The GRP provides complete interconnectivity between all of these elements. The ispLSI 1032E features 5-Volt in-system programmability and in-system diagnostic capabilities. The ispLSI 1032E device offers non-volatile reprogrammability of the logic, as well as the interconnects to provide truly reconfigurable systems. It is architecturally and parametrically compatible to the pLSI 1032E device, but multiplexes four input pins to control in-system programming. A functional superset of the ispLSI and pLSI 1032 architecture, the ispLSI and pLSI 1032E devices add two new global output enable pins.
