Microchip Technology's 24LC04 Serial EEPROM

The 24LC04 is a 4Kb I²C™ compatible Serial EEPROM (Electrically Erasable Programmable Read-Only Memory) product from Microchip Technology, a leading provider of smart, connected, and secure embedded control solutions. This device is designed for flexible, non-volatile storage in a wide range of applications, from industrial automation to consumer electronics.

This EEPROM operates across a voltage range of 2.5V to 5.5V, making it suitable for many low power and standard applications. It provides a user-friendly interface for easy integration into your projects with its I²C serial interface, supporting a clock frequency of up to 400kHz. The 24LC04 is organized as two blocks of 256 x 8-bit memory with a 2-wire serial interface. It offers a low standby current, which is ideal for battery-powered devices where power conservation is critical.

One of the key features of the 24LC04 is its page write capability of up to 16 bytes of data, which allows for faster and more efficient data storage operations. It also includes a self-timed erase/write cycle with a typical write cycle time of 5 ms, ensuring data integrity and reliability.

For security and data management, the 24LC04 provides a software write protect feature for the entire memory. Additionally, the device's built-in write protection helps prevent inadvertent writes to the memory during power-up or power-down sequences.

The 24LC04 is available in various surface-mount packages, including SOIC, TSSOP, and MSOP, which are suitable for space-constrained applications. It is also known for its high reliability, with an endurance of one million erase/write cycles and a data retention period of over 200 years.

Whether you are working on a complex industrial system or a simple consumer electronic device, the 24LC04 from Microchip Technology offers a practical and dependable solution for your data storage needs. Its ease of integration, low power consumption, and robust feature set make it an excellent choice for designers looking to enhance the performance and flexibility of their systems.
