X24164
2048 x 8 Bit
Serial E2PROM
FEATURES
DESCRIPTION
• 2.7V to 5.5V Power Supply
The X24164 is a CMOS 16,384 bit serial E2PROM,
internally organized 2048 x 8. The X24164 features a
serialinterfaceandsoftwareprotocolallowingoperation
on a simple two wire bus.
• Low Power CMOS
—Active Read Current Less Than 1 mA
—Active Write Current Less Than 3 mA
—Standby Current Less Than 50 µA
• Internally Organized 2048 x 8
• 2 Wire Serial Interface
Three device select inputs (S0–S2) allow up to eight
devices to share a common two wire bus.
Xicor E2PROMs are designed and tested for applica-
tions requiring extended endurance. Inherent data re-
tention is greater than 100 years.
—Bidirectional Data Transfer Protocol
• Sixteen Byte Page Write Mode
—Minimizes Total Write Time Per Byte
• Self Timed Write Cycle
—Typical Write Cycle Time of 5 ms
• High Reliability
—Endurance: 100,000 Cycles
—Data Retention: 100 Years
• Pin and Function Compatible with X24C16
• 8-Pin Plastic DIP and 8-Lead SOIC Packages
