Description

The AT27LV256A 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 3.0V to 3.6V in normal read mode operation, making it ideal for fast, portable systems using battery power.

Atmel’s innovative design techniques provide fast speeds that rival 5V parts while keeping the low power consump tion of a 3.3V supply. At VCC = 3.0V, any byte can be accessed in less than 55 ns. With a typical power dissipa tion of only 18 mW at 5 MHz and VC C = 3.3V, the AT27LV256A consumes less than one fifth the power of a standard 5V EPROM.

Standby mode supply current is typically less than 1 μA at 3.3V.
