Description
The ATF1504BE is a high-performance, high-density complex programmable logic device (CPLD) that utilizes Atmel’s proven electrically-erasable memory technology. With 64 logic macrocells and up to 68 inputs, it easily integrates logic from several TTL, SSI, MSI, LSI and classic PLDs. The ATF1504BE’s enhanced routing switch matrices increase usable gate count and the odds of successful pin-locked design modifications.
