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.
