The AT24C08C-STUM-T: A Robust 8-Kbit Serial EEPROM Solution from Microchip

In the realm of embedded systems and IoT devices, the reliable and efficient storage of configuration data, calibration constants, or operational parameters is paramount. The AT24C08C-STUM-T from Microchip Technology stands out as a premier solution for these non-volatile memory needs. This 8-Kbit (1024 x 8) serial EEPROM memory chip provides a perfect blend of density, performance, and reliability for a vast array of applications.

Operating over a broad voltage range of 1.7V to 5.5V, this device is exceptionally suited for both modern low-power systems and legacy 5V designs. Its low voltage capability makes it ideal for battery-powered portable electronics, where power efficiency is a critical design constraint. The chip leverages the ubiquitous and hardware-efficient I2C (Inter-Integrated Circuit) serial interface, allowing communication with a microcontroller using only two bidirectional lines: Serial Data (SDA) and Serial Clock (SCL). This significantly reduces board space and simplifies design complexity compared to parallel memory alternatives.

The AT24C08C-STUM-T is organized as 128 pages of 8 bytes each. It supports byte-level and page-level write operations, providing flexibility for both single-byte updates and more efficient multi-byte data logging. A critical feature for data integrity is its built-in hardware write-protect pin. When asserted, this pin prevents any write operations to the entire memory array, safeguarding vital data from accidental corruption. Furthermore, the device boasts an impressive endurance of 1 million write cycles and a data retention period of 100 years, ensuring long-term reliability.

Packaged in a space-saving 8-lead TSSOP, it is designed for high-density PCB layouts. Typical applications range from consumer electronics and industrial systems to medical devices and automotive modules, wherever small-sized, reliable, and low-power non-volatile memory is required.

ICGOOFind: The AT24C08C-STUM-T is a highly versatile and dependable I2C Serial EEPROM. Its low-voltage operation, robust hardware write-protection, and industry-standard interface make it an excellent choice for designers seeking to add compact, non-volatile memory to their systems with minimal design overhead.
