In-System Programmable High Density PLD

The ISPLSI3256E 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 ISPLSI3256E features 5V in-system programmability and in-system diagnostic capabilities. The ISPLSI3256E offers non-volatile reprogrammability of the Logic as well as the interconnect to provide truly reconfigurable systems. The basic unit of Logic on the ISPLSI3256E device is the Twin Generic Logic Block (Twin GLB) labelled A0, A1...H3. There are a total of 32 Twin GLBs in the ISPLSI3256E 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. By Lattice Semiconductor Corp.
