Description

The AT27BV040 chip is a high performance, low power, low voltage, 4,194,304-bit

one-time programmable read only memory (EPROM) organized as 512K 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.
