Description
The AT27LV020A is a high performance, low power, low voltage 2,097,152 bit one-
time programmable read only memory (OTP EPROM) organized as 256K by 8 bits. It
requires only one supply in the range of 3.0 to 3.6V in normal read mode operation,
making it ideal for fast, portable systems using battery power.
