Description
The ispLSI 1048C/883 is a High-Density Programmable
Logic Device processed in full compliance to MIL-STD-
883. This military grade device contains 288 Registers,
96 Universal I/O pins, 12 Dedicated Input pins, two
Global Output Enables (GOE), four Dedicated Clock
Input pins and a Global Routing Pool (GRP). The GRP
provides complete interconnectivity between all of these
elements. The isp LSI 1048C/883 features 5-Volt in system
programming and in-system diagnostic
capabilities.
Information :
It is the first device which offers non-volatile
reprogrammability of the logic, and the interconnect to
provide truly reconfigurable systems. Compared to the
ispLSI 1048, the ispLSI 1048C/883 offers two additional
dedicated inputs and two new Global Output Enable pins.
The basic unit of logic on the ispLSI 1048C/883 device is
the Generic Logic Block (GLB). The GLBs are labeled A0,
A1 .. F7 in figure 1. There are a total of 48 GLBs in the
ispLSI 1048C/883 devices. Each GLB has 18 inputs, a
programmable AND/OR/XOR 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 other GLB on the device.
