DESCRIPTION

The X24012 is a CMOS 1024 bit serial E2PROM,

internally organized as one 128 x 8 bank. The X24012

features a serial interface and software protocol allowing

operation on a simple two wire bus. Three address

inputs allow up to eight devices to share a common two wire

bus.

Xicor E2PROMs are designed and tested for applications

requiring extended endurance. Inherent data retention

is greater than 100 years. The X24012 is available in eight

pin DIP and SOIC packages.
