Description
The ispLSI 1024EA is a High Density Programmable
Logic Device containing 144 Registers, 48 Universal I/O
pins, two Dedicated Input pins, four Dedicated Clock
Input pins and a Global Routing Pool (GRP). The GRP
provides complete interconnectivity between all of these
elements. The ispLSI 1024EA features 5V in-system
diagnostic capabilities via IEEE 1149.1 Test Access Port.
The ispLSI 1024EA device offers non-volatile
reprogrammability of the logic, as well as the intercon-
nects to provide truly reconfigurable systems. A functional
superset of the ispLSI 1024 architecture, the ispLSI
1024EA device adds user selectable 3.3V or 5V I/O and
open-drain output options.
The basic unit of logic on the ispLSI 1024EA device is the
Generic Logic Block (GLB). The GLBs are labeled A0,
A1…D7 (Figure 1). There are a total of 24 GLBs in the
ispLSI 1024EA device. Each GLB has 18 inputs, a
programmable AND/OR/Exclusive OR array, and four
outputs which can be configured to be either combinato-
rial 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 other GLB on the device.
