atf22v10b 2 description the atf22v10b is a high performance cmos (electrically erasable) programmable logic device (pld) which utilizes atmels 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 military and industrial tempera- ture 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. absolute maximum ratings* temperature under bias................................ -55c to +125c *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. max- imum output pin voltage is v cc + 0.75v dc, which may overshoot to 7.0v for pulses of less than 20 ns. storage temperature ..................................... -65c to +150c 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 military operating temperature (case) 0c - 70c -40c - 85c -55c - 125c v cc power supply 5v 5% 5v 10% 5v 10%

atf22v10b 6 electronic signature word there are 64 bits of programmable memory that are always available to the user, even if the device is secured. these bits can be used for user-specific data. programming/erasing programming/erasing is performed using standard pld programmers. see cmos pld programming hardware and software suppor t for information on software/program- ming. input and i/o pull-ups all atf22v10b family members have internal input and i/o pull-up resistors. therefore, whenever inputs or i/os are not being driven externally, they will float to v cc . this ensures that all logic array inputs are at known states. these are relatively weak active pull-ups that can easily be overdriven by ttl-compatible drivers (see input and i/o diagrams below). input diagram i/o diagram
