Description
The ispLSI 2064E is a High Density Programmable Logic
Device. The device contains 64 Registers, 64 Universal
I/O pins, four 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 2064E features 5V in-system programmability and in-system diagnostic capabilities. The ispLSI
2064E offers non-volatile reprogrammability of the logic,
as well as the interconnect to provide truly reconfigurable
systems.
• ispLSI OFFERS THE FOLLOWING ADDED FEATURES
— Increased Manufacturing Yields, Reduced Time-toMarket 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
— 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 basic unit of logic on the ispLSI 2064E device is the
Generic Logic Block (GLB). The GLBs are labeled A0, A1
.. B7 (see Figure 1). There are a total of 16 GLBs in the
ispLSI 2064E device. 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.
