LC4256V-5TN144C

CPLD - 复杂可编程逻辑器件 PROGRAMMABLE SUPER FAST HI DENSITY PLD

3.3 V/2.5 V/1.8 V In-System Programmable  SuperFAST High Density PLDs

Overview LC4256V-5TN144C

The LC4256V-5TN144C ispMACH 4000 devices consist of multiple 36-input, 16-macrocell Generic Logic Blocks (GLBs) interconnected by a Global Routing Pool (GRP). Output Routing Pools (ORPs) connect the GLBs to the I/O Blocks (IOBs), which contain multiple I/O cells. This architecture is shown in Figure 1.
