Description

The ATF1502ASV 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 ATF1502ASV’s enhanced routing switch matrices

increase usable gate count and the odds of successful pin-locked design modifications.

The ATF1502ASV 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 signal, register clock, register reset or output enable. Each of these

control signals can be selected for use individually within each macrocell.
