AT27C040
Description
The AT27C040 chip is a low-power, high-performance, 4,194,304-bit one-time pro-
grammable read-only memory (OTP EPROM) organized as 512K by 8 bits. The
AT27C040 requires only one 5V power supply in normal read mode operation. Any
byte can be accessed in less than 70 ns, eliminating the need for speed reducing
WAIT states on high-performance microprocessor systems.
