ISPLSI1032E-70LJN

The ISPLSI1032E-70LJN is a high-density Complex Programmable Logic Device (CPLD) from Lattice Semiconductor, featuring 128 macrocells organized into 8 Generic Logic Blocks (GLBs). With 6000 usable gates and 64 I/O pins, it offers ample resources for mid-range logic designs. The device uses CMOS EEPROM technology, retaining configuration without external memory. In-system programmability allows field updates via JTAG interface. The 70MHz internal frequency and 7.5ns propagation delay support moderately high-speed logic operations in industrial and communications applications.

The ISPLSI1032E architecture centers on 8 Generic Logic Blocks (GLBs), each containing 16 macrocells. Each macrocell includes a programmable AND/OR array, configurable flip-flop, and output enable control. GLBs are interconnected through a Global Routing Pool (GRP) that provides signal paths between any GLB and any I/O cell. The Output Routing Pool (ORP) connects GLB outputs to I/O pins with flexible routing. Configuration data is stored in on-chip EEPROM cells, which are programmed via the JTAG interface. The device supports both synchronous and asynchronous design methodologies.
