AT27C080-90RC

The AT27C080-90RC chip is a low-power, high-performance 8,388,608-bit ultraviolet erasable programmable read only memory (EPROM) organized as 1M by 8 bits.The AT27C080-90RC requires only one 5V power supply in normal read mode operation.Any byte can be accessed in less than 90 ns, eliminating the need for speed reducing WAIT states on high-performance microprocessor systems.

The absolute maximum ratings of the AT27C080-90RC can be summarized as:(1):the parameter is temperature under bias,the rating is -55 to +125,the unit is ;(2):the parameter is storage temperature,the rating is -65 to +150,the unit is ;(3):the parameter is voltage on any pin with respect to ground,the rating is -2.0 to +7.0,the unit is V;(4):the parameter is voltage on A9 with respect to ground,the rating is -2.0 to +14.0,the unit is V;(5):the parameter is VPP supply voltage with respect to ground,the rating is -2.0 to +14.0,the unit is V;(6):the parameter is integrated UV erase dose,the rating is 7258,the unit is W`sec/cm2.

Stresses beyond those listed under "absolute maximum ratings"may cause permanent damage 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.
