Description
The ATF1516AS is a high performance, high density Complex Programmable Logic Device (CPLD) which utilizes Atmel’s proven electrically erasable technology. With 256 logic macrocells and up to 164 inputs, it easily integrates logic from several TTL, SSI, MSI, LSI and classic PLDs. The ATF1516AS’s enhanced routing switch matrices increase usable gate count, and increase odds of successful pin-locked design modifications.
