In-System Programmable High Density PLD
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 combinato-
rial or registered. All Twin GLB inputs come from the
GRP.
