The ispLSI 2096E is a High Density Programmable Logic  
Device. The device contains 96 Registers, 96 Universal  
I/O pins, six Dedicated Input pins, three Dedicated Clock  
Input pins, two dedicated Global OE input pins and a  
GlobalRouting Pool(GRP). TheGRPprovidescomplete  
interconnectivity between all of these elements. The  
ispLSI 2096E features 5V in-system programmability  
and in-system diagnostic capabilities. The ispLSI 2096E  
offers non-volatile reprogrammability of all logic, as well  
as the interconnect to provide truly reconfigurable sys-  
tems.  
• ispLSI OFFERS THE FOLLOWING ADDED FEATURES  
— Increased Manufacturing Yields, Reduced Time-to-  
Market and Improved Product Quality  
— Reprogram Soldered Devices for Faster Prototyping  
The basic unit of logic on the ispLSI 2096E device is the  
Generic Logic Block (GLB). The GLBs are labeled A0, A1  
.. C7 (see Figure 1). There are a total of 24 GLBs in the  
ispLSI 2096E device. 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.  
• OFFERS THE EASE OF USE AND FAST SYSTEM  
SPEED OF PLDs WITH THE DENSITY AND FLEXIBILITY  
OF FIELD PROGRAMMABLE GATE ARRAYS  
— Complete Programmable Device Can Combine Glue  
Logic and Structured Designs  
— Enhanced Pin Locking Capability  
— Three Dedicated Clock Input Pins  
— Synchronous and Asynchronous Clocks  
— Programmable Output Slew Rate Control to  
Minimize Switching Noise  
— Flexible Pin Placement  
— Optimized Global Routing Pool Provides Global  
Interconnectivity  
The device also has 96 I/O cells, each of which is directly  
connected to an I/O pin. Each I/O cell can be individually  
programmed to be a combinatorial input, output or bi-  
directional I/O pin with 3-state control. The signal levels  
are TTL compatible voltages and the output drivers can  
source 4 mA or sink 8 mA. Each output can be pro-  
grammed independently for fast or slow output slew rate
