The ATF16V8CZ-15PU is a high performance EECMOS programmable logic device in 20 pin DIP package. This device utilizes Atmel's proven electrically erasable flash memory technology. It significantly reduces total system power, enhances system reliability and reduces power supply cost. The supply current drops to less than 5µA typically when all the inputs and internal nodes are not switching. This automatic power down feature or sleep mode allows for power savings in slow clock systems and asynchronous applications.
