Cypress FLASH370 CPLDs

Cypress has family of CPLD products similar to Advanced Micro Devices and lattice devices. The Cypress CPLDs, FLASH370 is based on FLASH EEPROM technology. The FLASH370 parts are not in-system programmable. Figure below shows that FLASH370 has a typical CPLD architecture with multiple PAL blocks and a programmable interconnect matrix to connect them. Within each PAL block, there is an AND-array that feeds a product term allocator. This illustrates another type of flexibility available in PAL-like blocks in CPLDs, but not present in normal PALs.
