The ATF1502BE 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 ATF1502BE’s enhanced routing switch matrices increase usable gate count and the odds
of successful pin-locked design modifications.
The ATF1502BE has up to 32 bi-directional I/O pins and four dedicated input pins, depending on
the type of device package selected. Each dedicated pin can also serve as a global control sig-
nal, register clock, register reset or output enable. Each of these control signals can be selected
for use individually within each macrocell.
