AT27LV520
Atmel’s AT27LV520 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. Programing time is typically only 50 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 AT27LV520 programs exactly the same way as a standard 5V AT27C520 and
uses the same programming equipment.
