1. Description

The ATF1508BE is a high-performance, high-density complex programmable logic device

(CPLD) that utilizes Atmel’s proven electrically-erasable memory technology. With 128 logic

macrocells and up to 84 inputs, it easily integrates logic from several TTL, SSI, MSI, LSI and

classic PLDs. The ATF1508BE’s enhanced routing switch matrices increase usable gate count

and the odds of successful pin-locked design modifications.

The ATF1508BE has up to 80 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 TQFP and 132-ball CBGA pack-

ages, respectively.
