Description
The AT27BV020 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 2.7 to 3.6V in normal read mode operation,
making it ideal for fast, portable systems using either regulated or unregulated battery
power.
