... AT27BV256 consumes less than one fifth the power of a standard CC 5V EPROM. Standby mode supply current is typically less than 1 µA at 3V. The AT27BV256 simpli- fies system design and stretches battery lifetime even further by eliminating the need for power supply regulation. ...

... Product Identification Code electronically identifies the device and manufacturer. This feature is used by industry-standard programming equipment to select the proper program- ming algorithms and voltages. The AT27BV256 programs exactly the same way as a standard 5V AT27C256R and uses the same programming equipment. 2. Pin Configurations ...
