X24001

X24001 128 Bit X24001 Identi™PROM 16 x 8 Bit FEATURES 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. 2.7V to 5.5V Power Supply 128 Bit Serial E2PROM Low Power CMOS —Active Current Less Than 1mA —Standby Current Less Than 50µA Internally Organized 16 x 8 2 Wire Serial Interface High Voltage Programmable Only —VPGM, 12V to 15V Push/Pull Output High Reliability —Data Retention: 100 Years Available Packages —8-Lead MSOP —8-Lead PDIP —8-Lead SOIC FUNCTIONAL DIAGRAM PIN CONFIGURATION SCL CONTROL LOGIC COMMAND/ADDRESS REGISTER NC NC MSOP/DIP/SOIC 1 2 3 4 X24001 8 7 6 5 VCC NC SCL SDA SDA INPUT/ OUTPUT BUFFER NC SHIFT REGISTER VSS 3830 FHD F02.1 MEMORY ARRAY 3830 FHD F01 IDENTI™ PROM is a trademark of Xicor, Inc. © Xicor, Inc. 1991, 1995, 1996 Patents Pending 3830-1.5 6/10/96 T2/C1/D0 NS 1...
