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.

Atmel’s innovative design techniques provide fast speeds that rival 5V parts while keeping the low power consumption of a 3V supply. At VCC = 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 VCC = 3V, the AT27BV256 consumes less than one fifth the power of a standard 5V EPROM.
