DESCRIPTION
The X24001 is a CMOS 128 bit serial E2PROM, internally 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 applications 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 environment where VPGM is not available. Xicor E2PROMs are designed and tested for applications requiring extended endurance. Inherent data retention is greater than 100 years. The X24001 is fabricated with Xicor’s Advanced CMOS Floating Gate technology.
