Description
The AT27C020 is a low-power, high performance, 2,097,152-bit, one-time program-
mable read-only memory (OTP EPROM) organized as 256K by 8 bits. It requires only
one 5V power supply in normal read mode operation. Any byte can be accessed
in less than 55 ns, eliminating the need for speed-reducing WAIT states on high-
performance microprocessor systems.
