描述 Description

The ATF1504ASV(L) is a high-performance, high-density complex programmable logic device (CPLD) that utilizes Atmel’s proven electrically-erasable memory technology. With 64 logic acrocells and up to 68 inputs, it easily integrates logic from several TTL, SSI, MSI, LSI and classic PLDs. The ATF1504ASV(L)’s enhanced routing switch matrices increase usable gate count and the odds of successful pin-locked design modifications.
