AT27BV020-90JU

2-Megabit (256K x 8) Unregulated Battery-Voltage High Speed OTP EPROM

Atmel Corporation 

Atmel's AT27BV020 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 AT27BV020 programs exactly the same way as a standard 5V AT27C020

and uses the same programming equipment.
