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 applications
requiring extended endurance. Inherent data
retention is greater than 100 years. Available in DIP,
MSOP and SOIC packages.
