Description

The ispLSI 2032 and 2032A are High Density Program-

mable Logic Devices. The devices contain 32 Registers,

32 Universal I/O pins, two Dedicated Input Pins, three

Dedicated Clock Input Pins, one dedicated Global OE

input pin and a Global Routing Pool (GRP). The GRP

provides complete interconnectivity between all of these

elements. The ispLSI 2032 and 2032A feature 5V in-

system programmability and in-system diagnostic

capabilities. The ispLSI 2032 and 2032A offer non-

volatile reprogrammability of the logic, as well as the

interconnect to provide truly reconfigurable systems.

The basic unit of logic on these devices is the Generic

Logic Block (GLB). The GLBs are labeled A0, A1 .. A7

(Figure 1). There are a total of eight GLBs in the ispLSI

2032 and 2032A devices. Each GLB is made up of four

macrocells. Each GLB has 18 inputs, a programmable

AND/OR/Exclusive OR array, and four outputs which can

be configured to be either combinatorial or registered.

Inputs to the GLB come from the GRP and dedicated

inputs. All of the GLB outputs are brought back into the

GRP so that they can be connected to the inputs of any

GLB on the device.
