DESCRIPTION
The X24C02 is CMOS a 2048 bit serial E²PROM,
internally organized 256 x 8. The X24C02 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
retention is greater than 100 years. Available in DIP,
MSOP and SOIC packages.
