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 mac-
rocells 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.
The ATF1504BE has up to 64 bi-directional I/O pins and four dedicated input pins. Each dedi-
cated input 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.
Figures 1-1 and 1-2 show the pin assignments for the 100-lead and 44-lead TQFP packages
respectively.
