ATF2500C
1. Description
The ATF2500C is the highest-density PLD available in a 44-pin surface mount pack-
age. With its fully connected logic array and flexible macrocell structure, high gate
utilization is easily obtainable. The ATF2500C is a high-performance CMOS (electri-
cally-erasable) programmable logic device (PLD) that utilizes Atmel’s proven
electrically-erasable technology. This PLD is now available in a fully Green or LHF
(lead and halide-free) packages.
