The AT24C02D-SSHM-B: A Robust 2-Wire Serial EEPROM Solution from Microchip Technology

In the realm of embedded systems and IoT devices, the need for reliable, non-volatile memory for storing configuration data, calibration constants, or event logs is paramount. The AT24C02D-SSHM-B from Microchip Technology stands out as a premier solution, offering a robust and efficient method for data storage in a vast array of applications. This 2-Kbit serial EEPROM memory chip combines industry-standard compatibility with advanced features, making it an ideal choice for designers seeking performance and integration ease.

A key advantage of this memory IC is its utilization of the I²C (Inter-Integrated Circuit) 2-wire serial interface. This widely adopted protocol minimizes the number of GPIO pins required on a host microcontroller, simplifying board layout and reducing system cost. The interface supports a 400 kHz clock frequency, enabling efficient and rapid data transfer for time-sensitive operations. The device is organized as 256 x 8 bits, providing ample space for critical data without unnecessary overhead.

The AT24C02D-SSHM-B is engineered for enhanced reliability and durability. It features a 1,000,000 program/erase cycles endurance rating per byte and a data retention period of up to 100 years, ensuring data integrity over the entire lifespan of the end product. Its operation is guaranteed across an extensive voltage range from 1.7V to 5.5V, making it perfectly suited for both low-power battery-operated devices and standard 3.3V/5V systems.

Furthermore, this EEPROM incorporates critical hardware-level data protection. A dedicated hardware write-protect pin allows the host system to prevent any accidental writes to the entire memory array, safeguarding vital information from corruption. The device is also available in space-saving packages like the 8-lead SOIC, catering to the demands of modern, compact PCB designs.

ICGOODFIND: The AT24C02D-SSHM-B is a highly reliable and versatile serial EEPROM that excels in providing non-volatile memory storage with minimal system resource usage. Its combination of a standard I²C interface, wide voltage operation, superior endurance, and robust data protection mechanisms makes it an excellent component for consumer electronics, industrial systems, and medical devices.
