STMicroelectronics 24C04 Serial EEPROM

The 24C04 is a 4 Kbit Electrically Erasable Programmable Read-Only Memory (EEPROM) product from the renowned semiconductor manufacturer STMicroelectronics. This memory device is part of the 24Cxx series, where 'xx' represents the memory size. The 24C04, in particular, offers a storage capacity of 4 kilobits, organized as 512 bytes of 8 bits each, which is ideal for storing configurations, settings, or small amounts of data that need to be preserved during power-off scenarios.

One of the key features of the 24C04 is its compatibility with the I²C serial interface, which allows for easy integration into a wide range of applications. This interface supports a bidirectional two-wire bus and data transmission speeds of up to 400 kHz (Fast-mode) and 100 kHz (Standard-mode), enabling efficient communication with microcontrollers and other digital systems.

The device operates across a voltage range of 4.5V to 5.5V, which aligns with the common logic levels used in many digital circuits. This makes it suitable for use in various commercial, industrial, and automotive applications where data integrity and retention are crucial. The 24C04 also features a write control mechanism, including a hardware write protect pin and write time of 5 ms (typical), ensuring data reliability and preventing inadvertent writes during power transitions.

STMicroelectronics has designed the 24C04 with a focus on flexibility and endurance. The EEPROM is rated for a minimum of one million write cycles per byte and a data retention period of 40 years, guaranteeing long-term data persistence. Additionally, the device supports partial page writes, which is particularly useful for updating small amounts of data efficiently without the need to rewrite the entire page.

The 24C04 is available in various package options, including the standard 8-lead PDIP, 8-lead SOP, and TSSOP packages, providing designers with the flexibility to choose the appropriate form factor for their specific design requirements. With its robust feature set and proven reliability, the 24C04 from STMicroelectronics is a smart choice for applications requiring a small, non-volatile memory solution.
