数据手册.pdfCPLD - Complex Programmable Logic Devices 128 MC CPLD 7NS IND TEMP
Description
The ATF1508AS is a high-performance, high-density complex programmable logic device CPLD that utilizes Atmel’s proven electrically-erasable technology. With 128 logic macrocells and up to 100 inputs, it easily integrates logic from several TTL, SSI, MSI, LSI and classic PLDs. The ATF1508AS’s enhanced routing switch matrices increase usable gate count and increase odds of successful pin-locked design modifications.
