The ATF16V8B-15PU is a high-performance CMOS Electrically-erasable Programmable Logic Device that utilizes the Atmel proven electrically-erasable flash memory technology. All speed ranges are specified over the full 5.0V ±10% range for industrial temperature range. The ATF16V8B-15PU provides edge-sensing low-power PLD solution with low standby power consumption (5mA typical). The ATF16V8B-15PU powers down automatically to the low-power mode through the input transition detection (ITD) circuitry when the device is idle. The ATF16V8B-15PU incorporate a super set of the generic architectures, which allows direct replacement of the 16R8 family and most 20-pin combinatorial PLDs. Eight outputs are each allocated eight product terms. Three different modes of operation, configured automatically with software, allow highly complex logic functions to be realized.
