Atmel’s AT27BV512 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 algo-
rithms and voltages. The AT27BV512 programs exactly the same way as a standard 5V
AT27C512R and uses the same programming equipment.
