Description

Description
The ispLSI 3256A is a High-Density Programmable Logic Device containing 384 Registers, 128 Universal I/O pins, five Dedicated Clock Input Pins, eight Output Routing Pools (ORP) and a Global Routing Pool (GRP) which allows complete inter-connectivity between all of these elements. The ispLSI 3256A features 5V in-system programmability and in-system diagnostic capabilities. The ispLSI 3256A offers non-volatile reprogrammability of the logic, as well as the interconnect to provide truly reconfigurable systems.
The basic unit of logic on the ispLSI 3256A device is the Twin Generic Logic Block (Twin GLB) labelled A0, A1...H3. There are a total of 32 Twin GLBs in the ispLSI 3256A device. Each Twin GLB has 24 inputs, a programmable AND array and two OR/Exclusive-OR Arrays, and eight outputs which can be configured to be either combinatorial or registered. All Twin GLB inputs come from the GRP.
