X24012S

The X24012S is a CMOS 1024 bit serial E2PROM,internally organized as one 128 x 8 bank. The X24012S 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. The X24012S is available in eight pin DIP and SOIC packages.

The X24012S has some features such as:(1)2.7 to 5.5V power supply;(2)low power CMOS-active current less than 1 mA;(3)internally organized 128 x 8;(4)self timed write cycle-typical write cycle time of 5 ms;(5)2 wire serial interface-bidirectional data transfer protocol;(6)four byte page write operation-minimizes total write time per byte;(7)high reliability:-endurance:100,000 cycles.

The X24012S supports a bidirectional bus oriented proto- col.The protocol defines any device that sends data onto the bus as a transmitter,and the receiving device as the receiver.The device controlling the transfer is a master and the device being controlled is the slave.The master will always initiate data transfers and provide the clock for both transmit and receive operations. Therefore,the X24012S will be considered a slave in all applications.
