Description  
• 100% IEEE 1149.1 BOUNDARY SCAN COMPATIBLE  
TheispLSI3256AisaHigh-DensityProgrammableLogic  
Device containing 384 Registers, 128 Universal I/O pins,  
five Dedicated Clock Input Pins, eight Output Routing  
Pools (ORP) and a Global Routing Pool (GRP) which  
allows complete inter-connectivity between all of these  
elements. The ispLSI 3256A features 5V in-system  
programmability and in-system diagnostic capabilities.  
The ispLSI 3256A offers non-volatile reprogrammability  
of the logic, as well as the interconnect to provide truly  
reconfigurable systems.  
• 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  
— 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  
The basic unit of logic on the ispLSI 3256A device is the  
TwinGenericLogicBlock(TwinGLB)labelledA0,A1...H3.  
There are a total of 32 Twin GLBs in the ispLSI 3256A  
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.
