Description The ATF16V8CZ is a high-performance EECMOS programmable logic device that utilizes Atmel’s proven electrically-erasable Flash memory technology. Speeds down to 12 ns and a 5 µA (Typ) edge-sensing power-down mode are offered. All speed ranges are specified over the full 5V ±10% range for industrial temperature ranges; 5V ±5% for mercial range 5-volt devices. The ATF16V8CZ incorporates a superset of the generic architectures, which allows direct replacement of the 16R8 family and most 20-pin binatorial PLDs. Eight outputs are each allocated eight product terms. Three different modes of operation, configured automatically with software, allow highly plex logic functions to be realized. The ATF16V8CZ can significantly reduce total system power, thereby enhancing system reliability and reducing power supply costs. When all the inputs and internal nodes are not switching, supply current drops to less than 5 µA typically. This automatic power-down feature (or sleep mode) allows for power savings in slow clock systems and asynchronous applications. Also, the pin-keeper circuits eliminate the need for internal pull-up resistors along with their attendant power consumption. 0453H- PLD- 7/05 Figure 1-1. Block Diagram 2. Pin Configuration and...
