The ispLSI 2128 and 2128A are High Density Programmable Logic Devices. The devices contains128 Registers,
128 Universal I/O pins, eight Dedicated Input pins, three
Dedicated Clock Input pins, two dedicated Global OE
input pins and a Global Routing Pool (GRP). The GRP
provides complete interconnectivity between all of these
elements. The ispLSI 2128 and 2128A feature 5V insystem programmability and in-system diagnostic
capabilities. The ispLSI 2128 and 2128A offer nonvolatile 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 .. D7
(Figure 1). There are a total of 32 GLBs in the ispLSI 2128
and 2128A 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.
