NM27C020
2,097,152-Bit (256K x 8) UV Erasable CMOS EPROM
General Description
The NM27C020 is a high speed 2 Megabit CMOS UV-EPROM manufactured on Fairchild’s advanced sub-micron technology. Utilizing the AMG architecture, this advanced CMOS process delivers high speeds while consuming low power.
The NM27C020 provides microprocessor-based systems extensive storage capacity for large portions of operating systems and application software. Its 100ns access time provides no-wait-state operation with high-performance CPUs.
The NM27C020 offers a single chip solution for the code storage requirements of 100% firmware-based equipment. Frequentlyused software routines are quickly executed from EPROM storage, greatly enhancing system utility.
The NM27C020 is manufactured using Fairchild’s advanced CMOS AMG EPROM technology, and is one member of a high density Fairchild EPROM series family which range in densities up to 4Mb.

Note 1: Stresses above 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 above those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods of time may affect device reliability.
Note 2: The supply current is the sum of ICC and IPP. The maximum current value is with Outputs O0 to O7 unloaded.
Note 3: This parameter is only sampled and is not 100% tested. Output Float is defined as the point where data is no longer driven-see timing diagram.
Note 4: CMOS inputs: VIL = GND 10.3V, VIH = VCC 10.3V.
