AT27BV4096
Atmel’s AT27BV4096 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/word. 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 AT27BV4096 programs exactly the same way as a standard 5V AT27C4096
and uses the same programming equipment.
Note:
Note: PLCC package pins 1 and 23 are Don’t Connect.
