Description The ATF16V8B is a high-performance CMOS (electricallyerasable) programmable logic device (PLD) that utilizes Atmels 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. 0364JPLD7/05Figure 1-1. Block Diagram 2. Pin Configurations Table 2-1.
