AT27LV520-70SU

512K (64K x 8) Multiplexed Addresses/ Outputs Low-voltage OTP EPROM

Atmel Corporation 

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.
