X24001
Identi^™PROM
16 x 8 Bit
DESCRIPTION
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.
V_PGM is used to enable writes to the device. This
provides full protection of the data in the user’s environ-
ment where V_PGM 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.
