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.
The 24C04 is widely used in various electronic systems requiring compact, non-volatile memory storage. Typical applications include:
