The AT24C02C-STUM-T: A Robust 2-Wire Serial EEPROM Solution from Microchip Technology

In the realm of embedded systems and IoT devices, reliable non-volatile memory is a fundamental component for storing critical data. The AT24C02C-STUM-T from Microchip Technology stands out as a premier solution in the 2-Kbit serial EEPROM category, offering a blend of performance, endurance, and ease of integration that designers require.

This memory chip organizes its 2 kilobits of space into 256 words of 8 bits each, providing sufficient storage for a wide array of application parameters, from device configuration and calibration data to user settings and transaction logs. A key feature of the AT24C02C is its utilization of the ubiquitous I²C (Inter-Integrated Circuit) 2-wire serial interface. This industry-standard protocol minimizes the number of GPIO pins required from the host microcontroller, significantly simplifying board layout and reducing system cost. The device supports a maximum clock frequency of 1MHz (1.8V to 5.5V), enabling high-speed read operations for efficient data access.

Designed for robustness and longevity, this EEPROM boasts an impressive endurance of over 1 million write cycles. This makes it highly suitable for applications where data is updated frequently. Furthermore, it features a data retention period of 100 years, ensuring information integrity over the entire lifetime of the end product. The device operates across a broad voltage range from 1.7V to 5.5V, accommodating everything from low-power, battery-operated gadgets to standard 5V systems. Its extended temperature range ensures reliable operation in demanding environments.

Housed in a space-saving 5-lead SOT-23 package, the AT24C02C-STUM-T is ideal for space-constrained applications such as wearable technology, smart sensors, and portable medical devices. It also includes hardware write-protection capabilities, adding a crucial layer of security against accidental data corruption.

ICGOODFIND: The AT24C02C-STUM-T is a highly reliable and efficient serial EEPROM that delivers essential non-volatile memory functions with minimal system overhead. Its combination of a standard interface, exceptional endurance, and wide voltage operation makes it an excellent choice for modern electronic design.
