ATF16V8CZ 2 description the ATF16V8CZ is a high-performance eecmos programmable logic device which utilizes atmel ? s proven electrically-erasable flash memory technology. speeds down to 12 ns and a 25 a 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 commercial 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 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. 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 25 a. this automatic power-down feature allows for power savings in slow clock systems and asynchronous applica- tions. also, the pin keeper circuits eliminate the need for internal pull-up resistors along with their attendant power consumption. absolute maximum ratings* temperature under bias.................................. -40 c to +85 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. maximum 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 (ambient) 0 c - 70 c-40 c - 85 c v cc power supply 5v 5% 5v 10%

ATF16V8CZ 6 registered output preload the ATF16V8CZ ? s registers are provided with circuitry to allow loading of each register with either a high or a low. this feature will simplify testing since any state can be forced into the registers to control test sequencing. a jedec file with preload is generated when a source file with vectors is compiled. once downloaded, the jedec file preload sequence will be done automatically by approved programmers. security fuse usage a single fuse is provided to prevent unauthorized copying of the ATF16V8CZ fuse patterns. once programmed, fuse verify and preload are inhibited. however, the 64-bit user signature remains accessible. the security fuse should be programmed last, as its effect is immediate. input and i/o pin keeper circuits the ATF16V8CZ contains internal input and i/o pin keeper circuits. these circuits allow each ATF16V8CZ pin to hold its previous value even when it is not being driven by an external source or by the device's output buffer. this helps insure that all logic array inputs are at known, valid logic levels. this reduces system power by preventing pins from floating to indeterminate levels. by using pin keeper circuits rather than pull-up resistors, there is no dc current required to hold the pins in either logic state (high or low). these pin keeper circuits are implemented as weak feed- back inverters, as shown in the input diagram below. these keeper circuits can easily be overdriven by standard ttl- or cmos-compatible drivers. the typical overdrive current required is 40 a. input diagram i/o diagram note: 1. only applicable for version 3.4 or lower. compiler mode selection registered complex simple auto select abel, atmel-abel p16c8r p16v8c p16v8as p16v8 cupl g16v8ms g16v8ma g16v8as g16v8a log/ic gal16v8_r (1) gal16v8_c7 (1) gal16v8_c8 (1) gal16v8 orcad-pld ? registered ?? complex ?? simple ? gal16v8a pldesigner p16v8r p16v8c p16v8c p16v8a tango-pld g16v8r g16v8c g16v8as g16v8
