Description

The AT27C080 chip is a low-power, high-performance 8,388,608-bit ultraviolet eras-

able programmable read only memory (EPROM) organized as 1M by 8 bits. The

AT27C080 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.

Atmel’s scaled CMOS technology provides low active power consumption and fast

programming. Power consumption is typically 10 mA in active mode and less than 10

µA in standby mode.
