AT27C080
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鈥檚 scaled CMOS technology provides low active power consumption and fast
programming. Power consumption is typically 10 mA in active mode and less than 10
碌A(chǔ)
in standby mode.
