1. Description
The ATF16V8B is a high-performance CMOS (electricallyerasable) programmable
logic device (PLD) that utilizes Atmel’s proven electrically-erasable Flash memory
technology. All speed ranges are specified over the full 5V ± 10% range for industrial
temperature ranges, and 5V ± 5% for commercial temperature ranges.
Several low-power options allow selection of the best solution for various types of
power-limited applications. Each of these options significantly reduces total system
power and enhances system reliability.
The ATF16V8Bs incorporate a superset of the generic architectures, which allows
direct replacement of the 16R8 family and most 20-pin combinatorial PLDs. Eight out-
puts are each allocated eight product terms. Three different modes of operation,
configured automatically with software, allow highly complex logic functions to be
realized.
