This document introduces the features and characteristics of the X24012 128 x 8 bit serial E2PROM, including power supply voltage, power consumption, storage capacity, storage time, interface type, data transfer protocol, etc.
The X24012 is a 1024‑bit (128 × 8) CMOS serial E2PROM organized as a single memory bank. It operates from 2.7 V to 5.5 V and features a low‑power design with active current under 1 mA and standby current below 50 µA. The device supports a two‑wire (SCL/SDA) serial interface, bidirectional data transfer, and page‑write capability of up to four bytes.
The part is supplied in 8‑lead DIP and 8‑lead SOIC packages, with temperature ranges from commercial (0 °C to +70 °C) to industrial (‑40 °C to +85 °C). Endurance is rated at 100 000 write cycles and data retention exceeds 100 years. Detailed pin descriptions, timing diagrams, and operation modes (byte write, page write, current‑address read, random read, sequential read) are provided.
