The LC4256V-75TN100C is a high performance SuperFAST CPLD consist of multiple 64-I/O, 256-macrocell. Output Routing Pools (ORPs) connect the GLBs to the I/O Blocks (IOBs), which contain multiple I/O cells. The ispMACH 4000 family is a blend of Lattice's two most popular architectures, the ispLSI? 2000 and ispMACH 4A. Retaining the best of both families, the ispMACH 4000 architecture focuses on significant innovations to combine the highest performance with low power in a flexible CPLD family. This family combines high speed and low power with the flexibility needed for ease of design. With its robust global routing pool and output routing pool, this family delivers excellent first-time-fit, timing predictability, routing, pin-out retention and density migration. It has enhanced system integration capabilities. Also offers enhanced I/O features such as slew rate control, PCI compatibility, bus-keeper latches, pull-up resistors, pull-down resistors, open drain outputs and hot socketing.
