AT27BV040

Atmel’s AT27BV040 has additional features to ensure high quality and efficient production use.

The Rapid Programming Algorithm reduces the time required to program the part and guaran-

tees 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 AT27BV040 programs exactly the same way as a standard 5V AT27C040

and uses the same programming equipment.
