16 x 8 Bit
The X24001 is a CMOS 128 bit serial E2PROM, inter-
nally organized as 16 x 8. The X24001 features a serial
interface and software protocol allowing operation on a
simple two wire bus.
The X24001 is ideally suited for identification applica-
tions such as serial numbers or device revision numbers
which need to be stored and retrieved electronically.
VPGM is used to enable writes to the device. This
provides full protection of the data in the user’s environ-
ment where VPGM is not available.
Xicor E2PROMs are designed and tested for applica-
tions requiring extended endurance. Inherent data re-
tention is greater than 100 years.
The X24001 is fabricated with Xicor’s Advanced CMOS
Floating Gate technology.
