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.

AC Waveforms for Read Operation(1)
AT27C080
Notes: 1. Timing measurement references are 0.8V and 2.0V. Input AC drive levels are 0.45V and 2.4V, unless otherwise specified.
2. tDF is specified form OE/VPP or CE, whichever occurs first. Output float is defined as the point when data is no longer
driven.
3. OE/VPP may be delayed up to tCE - tOE after the falling edge of CE without impact on tCE.
4. OE/VPP may be delayed up to tACC- tOE after the address is valid without impact on tACC.
5. This parameter is only sampled and is not 100% tested.
