AT24C16C-SSHM-T: A High-Reliability 16-Kbit Serial EEPROM for Modern Embedded Systems

The AT24C16C-SSHM-T is a 16-Kbit I2C-compatible serial EEPROM memory chip designed to provide reliable non-volatile data storage in a wide array of consumer, industrial, and automotive applications. Manufactured by Microchip Technology, this device combines a robust feature set with the simplicity of the ubiquitous I2C protocol, making it an ideal solution for storing configuration parameters, calibration data, and other critical information in systems where power may be intermittent.

Organized as 2048 words x 8 bits (2 KByte), the memory array is designed for efficient byte-level and page-level read/write operations. A significant advantage of this EEPROM is its 1MHz (1.7V to 5.5V) clock frequency, which supports high-speed communication across a broad voltage range, enhancing its versatility for both low-power and performance-oriented designs. The device operates on a single power supply from 1.7V to 5.5V, ensuring compatibility with various logic levels without needing a level translator.

Key to its design is high reliability and endurance. The AT24C16C-SSHM-T boasts a endurance of 1,000,000 write cycles, far exceeding many basic storage solutions, and guarantees data retention for over 100 years. This makes it exceptionally suited for applications requiring frequent updates and long-term data integrity. Furthermore, the 16-byte page write buffer allows for more efficient data writing by minimizing the number of write cycles and reducing overall protocol overhead.

The SSHM-T package suffix denotes a 8-lead SOIC package, which is easy to handle for both prototyping and mass production. The chip also includes advanced hardware data protection mechanisms. Write protection is enabled by connecting the WC (Write Control) pin to GND or VCC, safeguarding the entire memory array from unintended writes. For finer control, the array can be software write-protected through the identification page.

In application, the AT24C16C-SSHM-T is commonly used in smart meters, automotive telematics, networking equipment, IoT sensors, and industrial control systems. Its ability to operate across an extended temperature range and its high noise immunity make it a dependable choice in harsh environments.

ICGOODFIND: The AT24C16C-SSHM-T stands out as a highly reliable, versatile, and easy-to-integrate non-volatile memory solution, offering an optimal balance of capacity, performance, and durability for modern electronic designs.
