Description
— fmax = 125 MHz Maximum Operating Frequency
— tpd = 7.5 ns Propagation Delay
The ispLSI 2096 and 2096A are High Density Program-
mable Logic Devices. The devices contain 96 Registers,
96 Universal I/O pins, six 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 2096 and 2096A feature 5V in-
system programmability and in-system diagnostic
capabilities. The ispLSI 2096 and 2096A offer non-
volatile reprogrammability of the logic, as well as the
interconnect to provide truly reconfigurable systems.
— TTL Compatible Inputs and Outputs
— Electrically Erasable and Reprogrammable
— Non-Volatile
— 100% Tested at Time of Manufacture
— Unused Product Term Shutdown Saves Power
• IN-SYSTEM PROGRAMMABLE
— In-System Programmable (ISP™) 5V Only
— Increased Manufacturing Yields, Reduced Time-to-
Market and Improved Product Quality
— Reprogram Soldered Devices for Faster Prototyping
• OFFERS THE EASE OF USE AND FAST SYSTEM
SPEED OF PLDs WITH THE DENSITY AND FLEXIBILITY
OF FIELD PROGRAMMABLE GATE ARRAYS
The basic unit of logic on these devices is the Generic
Logic Block (GLB). The GLBs are labeled A0, A1…C7
(Figure1). Thereareatotalof24GLBsintheispLSI2096
and 2096A devices. Each GLB is made up of four
macrocells. Each GLB has 18 inputs, a programmable
AND/OR/ExclusiveORarray, andfouroutputswhichcan
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.
