24C04 Technical Summary

24C04 I2C-Compatible Serial EEPROM

Overview

The 24C04 is a 4K-bit (512 x 8) serial Electrically Erasable Programmable Read-Only Memory (EEPROM) that operates across a broad voltage range (1.7V to 5.5V). This device features an I2C-compatible (Inter-Integrated Circuit) two-wire serial interface, making it ideal for applications requiring non-volatile memory storage with minimal pin count. The 24C04 is organized as 512 words of 8 bits each and supports byte-wise and page-wise write operations.

Key advantages of the 24C04 include its low power consumption, high reliability, and extended endurance (up to 1 million write cycles). The device also incorporates advanced write protection features, including software and hardware write protection options to prevent accidental data corruption.
