DESCRIPTION

The X24C01A is a CMOS 1024 bit serial E2PROM,

internally organized 128 x 8. The X24C01A 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 applica-

tions requiring extended endurance. Inherent data re-

tention is greater than 100 years. Available in an eight

pin DIP and SOIC package.
