Description

The ispLSI 2032VE is a High Density Programmable

Logic Device that can be used in both 3.3V and 5V

systems. The device contains 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 2032VE features in-system programmability

through the Boundary Scan Test Access Port (TAP) and

is 100% IEEE 1149.1 Boundary Scan Testable. The

ispLSI 2032VE 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 2032VE device is the

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

.. A7 (see Figure 1). There are a total of eight GLBs in the

ispLSI 2032VE device. 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.
