Description
The AT27BV256 is a high performance, low power, low voltage 262,144-bit one-time
programmable read only memory (OTP EPROM) organized as 32K by 8 bits. It
requires only one supply in the range of 2.7V to 3.6V in normal read mode operation,
making it ideal for fast, portable systems using either regulated or unregulated battery
power.
