Description
The ATF1502AS is a high-performance, high-density complex programmable logic device (CPLD) that utilizes Atmel’s proven electrically-erasable technology. With 32 logic macrocells and up to 36 inputs, it easily integrates logic from several TTL, SSI, MSI, LSI and classic PLDs. The ATF1502AS’s enhanced routing switchmatrices increase usable gate count and the odds of successful pin-locked design modifications.
