It requires only one supply in the range of 3.0 to 3.6V in normal read mode operation, making it ideal for fast, portable systems using battery power.

At V CC = 3.0V, any byte can be accessed in less than 90 ns. With a typical power dissipation of only 18 m W at 5 MHz and V C C = 3.3V, the AT27LV020A 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. The AT27LV020A is available in industry standard JEDEC approved one-time programmable (OTP) plastic PLCC, TSOP and VSOP packages. All devices feature two-line control (CE, OE) to give designers the flexibility to prevent bus contention. The AT27LV020A operating with V CC at 3.0V produces TTL level...
