AT24C08D-STUM-T: A Robust 8-Kb Serial EEPROM Solution by Microchip

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 AT24C08D-STUM-T from Microchip Technology stands out as a high-performance, 8-Kbit I2C-compatible serial EEPROM designed to meet these critical requirements with exceptional efficiency and reliability.

This memory IC organizes its 8,192 bits into 1024 x 8 (1K) bytes, providing ample space for small to medium data storage tasks. Its operation via the ubiquitous I2C serial interface allows for communication with just two bidirectional lines (SDA and SCL), significantly reducing system wiring complexity and saving valuable GPIO pins on the host microcontroller. The device supports a wide voltage range from 1.7V to 5.5V, making it exceptionally versatile for use in both modern low-power designs and legacy 5V systems.

A key feature of the AT24C08D is its enhanced write protection scheme. Through careful manipulation of the device address pins (A2, A1, and A0), the entire memory array can be write-protected, safeguarding critical data from accidental corruption. This is particularly vital in applications where data integrity is non-negotiable. Furthermore, the device boasts a 1 MHz (1.7V to 5.5V) clock frequency, enabling high-speed data transfer for faster read and write operations, which enhances overall system performance.

Packaged in a space-saving 8-lead TSSOP, the AT24C08D-STUM-T is ideal for space-constrained applications. It is engineered for low-power consumption, featuring a standby current of just 6 µA (max), which is crucial for battery-powered portable electronics. With an endurance of 1 million write cycles and a data retention period of 100 years, this EEPROM is built for long-term, dependable operation in demanding environments such as industrial control, automotive systems, smart meters, and consumer electronics.

ICGOOODFIND: The AT24C08D-STUM-T is a superior choice for designers seeking a compact, reliable, and high-performance non-volatile memory solution. Its combination of I2C compatibility, robust data protection, wide voltage operation, and industry-leading endurance makes it an indispensable component for modern electronic design.
