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 consumption of a 3.3V supply. At VCC = 3.0V, any byte can be accessed in less than 70 ns. With a typical power dissipation of only 18 m W at 5 MHz and VCC = 3.3V, the AT27LV256A consumes less than one fifth the power of a standard 5V EPROM.

The AT27LV256A is available in industry standard JEDEC-approved one-time programmable (OTP) plastic PLCC, SOIC and TSOP packages . All devices feature two-line control (CE, OE) to give designers the flexibility to prevent bus contention....
