5V Power Supply Low Power CMOS —Active Current Less Than 1 mA —Standby Current Less Than 50 µA Internally Organized 128 x 8 Self Timed Write Cycle —Typical Write Cycle Time of 5 ms 2 Wire Serial Interface —Bidirectional Data Transfer Protocol Four Byte Page Write Operation —Minimizes Total Write Time Per Byte High Reliability —Endurance: 100,000 Cycles —Data Retention: 100 Years New Hardwire – Write Control Function The X24C01A is a CMOS 1024 bit serial E2PROM, internally organized 128 x 8.
The X24C01A features a serial interface and software protocol allowing operation on a simple two wire bus.
Three address inputs allow up to eight devices to share a common two wire bus.
Xicor E2PROMs are designed and tested for applications requiring extended endurance.
Inherent data retention is greater than 100 years.
Available in an eight pin DIP and SOIC package.

Serial Data (SDA) SDA is a bidirectional pin used to transfer data into and out of the device.
It is an open drain output and may be wire-ORed with any number of open drain or open collector outputs.
An open drain output requires the use of a pull-up resistor.
For selecting typical values, refer to the Guidelines for Calculating Typical Values of Bus Pull-Up Resistors graph.
Address (A0, A1, A2) The address inputs are used to set the least significant three bits of the seven bit slave address.
