2 / 17 page ATF20V8B 2 Description The ATF20V8B is a high performance CMOS (Electrically Erasable) Programmable Logic Device (PLD) which utilizes Atmel’s proven electrically erasable Flash memory technol- ogy. Speeds down to 7.5 ns and power dissipation as low as 10 mA are offered. 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 solu- tion for various types of power-limited applications. Each of these options significantly reduces total system power and enhances system reliability. The ATF20V8Bs incorporate a superset of the generic architectures, which allows direct replacement of the 20R8 family and most 24-pin combinatorial PLDs. Eight outputs are each allocated eight product terms. Three different modes of operation, configured automatically with soft- ware, allow highly complex logic functions to be realized. Absolute Maximum Ratings* Temperature Under Bias ................................ -55°C to +125°C *NOTICE: Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent dam- age to the device. This is a stress rating only and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. Note: 1. Minimum voltage is -0.6V DC which may under- shoot to -2.0V for pulses of less than 20 ns.Maxi- mum output pin voltage is V CC + 0.75V DC which may overshoot to 7.0V for pulses of less than 20 ns. Storage Temperature ..................................... -65°C to +150°C Voltage on Any Pin with Respect to Ground .........................................-2.0V to +7.0V(1) Voltage on Input Pins with Respect to Ground During Programming.....................................-2.0V to +14.0V(1) Programming Voltage with Respect to Ground .......................................-2.0V to +14.0V(1) DC and AC Operating Conditions Commercial Industrial Operating Temperature (Case) 0°C - 70°C -40°C - 85°C V CC Power Supply 5V ± 5% 5V ± 10% |
