ispLSI3256E Description：

The ispLSI 3256E is a High Density Programmable Logic
Device containing 512 Registers, 256 Universal I/O pins,
five Dedicated Clock Input Pins, 16 Output Routing Pools
(ORP) and a Global Routing Pool (GRP) which allows
complete inter-connectivity between all of these elements.
The ispLSI 3256E features 5V in-system
programmability and in-system diagnostic capabilities.
The ispLSI 3256E 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 3256E device is the
Twin Generic Logic Block (Twin GLB) labelled A0, A1...H3.
There are a total of 32 Twin GLBs in the ispLSI 3256E
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.
