Logic and Structured Designs

The ispLSI 3256E is a High Density Programmable Logic

Device containing 512 Registers, 256 Universal I/O pins,

five Dedicated Clock Input Pins, 16 Output Routing Pools

(ORP) and a Global Routing Pool (GRP) which allows

complete inter-connectivity between all of these ele-

ments. The ispLSI 3256E features 5V in-system

programmability and in-system diagnostic capabilities.

The ispLSI 3256E offers non-volatile reprogrammability

of the logic, as well as the interconnect to provide truly

reconfigurable systems.

— Five Dedicated Clock Input Pins

— Synchronous and Asynchronous Clocks

— Programmable Output Slew Rate Control to Mini-

mize Switching Noise

— Flexible Pin Placement

— Optimized Global Routing Pool Provides Global

Interconnectivity

• ispDesignEXPERT™ – LOGIC COMPILER AND COM-

PLETE ISP DEVICE DESIGN SYSTEMS FROM HDL

SYNTHESIS THROUGH IN-SYSTEM PROGRAMMING

The basic unit of logic on the ispLSI 3256E device is the

TwinGenericLogicBlock(TwinGLB)labelledA0,A1...H3.

There are a total of 32 Twin GLBs in the ispLSI 3256E

device. Each Twin GLB has 24 inputs, a programmable

AND array and two OR/Exclusive-OR Arrays and eight

outputs which can be configured to be either combinato-

rial or registered. All Twin GLB inputs come from the

GRP.

— Superior Quality of Results

— Tightly Integrated with Leading CAE Vendor Tools

— Productivity Enhancing Timing Analyzer, Explore
