CAT24M01WI-GT3 – EEPROM Memory IC | 1Mbit, I2C Interface, 1MHz | SOIC-8 Package
The CAT24M01WI-GT3 from onsemi is a high-density 1Mbit (131,072×8) Serial Electrically Erasable Programmable Read-Only Memory (EEPROM) designed for high-reliability and low-power applications. Featuring an I2C-compatible serial interface, it supports Standard (100 kHz), Fast (400 kHz), and Fast-Plus (1 MHz) I2C bus modes, making it suitable for a wide range of embedded, industrial, and consumer systems. The EEPROM includes a 256-byte page write buffer, hardware write protection, and on-chip ECC (Error Correction Code) to ensure data integrity and long-term reliability. Operating across a wide 1.8V to 5.5V supply range, it offers exceptional endurance and retention, ideal for non-volatile data storage in compact designs.
