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. Standby mode supply current is typically less than 1 µA at 3V. The AT27BV256 simplifies system design and stretches battery lifetime even further by eliminating the need for power supply regulation. The AT27BV256 is available in industry standard JEDECapproved 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. The AT27BV256 operating with VCC at 3.0V produces TTL level outputs that are compatible with standard TTL logic devices operating at VCC = 5.0V. At VCC = 2.7V, the part is compatible with JEDEC approved low voltage battery operation LVBO interface specifications. The device is also capable of standard 5-volt operation making it ideally suited for dual supply range systems or card products that are pluggable in both 3-volt and 5-volt hosts. Atmel’s AT27BV256 has additional features to ensure high quality and efficient production use. The Rapid Program- ming Algorithm reduces the time required to program the part and guarantees reliable programming. Programming time is typically only 100 µs/byte. The Integrated Product Identification Code electronically identifies the device and manufacturer. This feature is used by industry standard programming equipment to select the proper programming algorithms and voltages. The AT27BV256 programs exactly the same way as a standard 5V AT27C256R and uses the same programming equipment.
