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 applications
requiring extended endurance. Inherent data retention
is greater than 100 years. Available in an eight pin DIP and
SOIC package.
