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 re-
quires 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.
Atmel’s innovative design techniques provide fast speeds that rival 5V parts while
keeping the low power consumption of a 3V supply. At V
CC
= 2.7V, any word can be
accessed in less than 70 ns. With a typical power dissipation of only 18 mW at 5 MHz
and V
CC
= 3V, the AT27BV256 consumes less than one fifth the power of a standard
5V EPROM.
