The X24022 is a CMOS 2048 bit serial E2PROM, internally organized 256 x 8. The X24022 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 X24022 is available in eight pin DIP and SOIC packages.
The X24022 serial E2PROM provides 256 × 8 bits of non‑volatile memory organized internally. It operates from 2.7 V to 5.5 V, draws less than 1 mA in active mode and less than 50 pA in standby, and supports a four‑byte page write to minimize write time.
The device uses a two‑wire serial interface (SCL, SDA) with bidirectional data transfer, three address inputs for up to eight devices on a bus, and offers endurance of 100 000 write cycles per byte with a data‑retention guarantee of 100 years. It is available in 8‑lead plastic DIP and 8‑lead SOIC packages.
