The Microchip 24LC16B-E/SN: A Robust 16K I²C Serial EEPROM Solution

In the realm of embedded systems and electronics, reliable non-volatile memory is a fundamental component for storing critical data. The Microchip 24LC16B-E/SN stands out as a premier choice, offering designers a robust and highly versatile 16Kbit serial EEPROM memory chip. This device is engineered for simplicity and efficiency, leveraging the ubiquitous I²C (Inter-Integrated Circuit) serial communication protocol for easy integration into a vast array of applications.

Housed in a space-saving 8-lead SOIC (SN) package, this EEPROM is designed for commercial and industrial grade temperature ranges. Its 16Kbit memory space is organized as 8 blocks of 256 bytes each, providing flexible storage for data logging, configuration settings, and calibration constants. A key feature of the 24LC16B is its page write capability, allowing up to 16 bytes to be written in a single operation, which significantly enhances write efficiency and reduces processor overhead.

The chip operates on a wide voltage range from 1.7V to 5.5V, making it perfectly suited for both 5V and modern low-voltage 3.3V systems. This low power consumption is critical for battery-powered devices. Furthermore, it features hardware write-protection, with a dedicated pin that, when connected to VSS, prevents any inadvertent writes to the entire memory array, thereby safeguarding vital information.

With its 1 MHz clock frequency compatibility, it ensures adequate speed for most common data storage tasks. The 24LC16B-E/SN is also characterized by its high endurance, supporting over 1 million erase/write cycles and offering data retention greater than 200 years, guaranteeing long-term reliability.

Typical applications are extensive, ranging from consumer electronics and smart meters to industrial automation and automotive subsystems, wherever small-scale, dependable data storage is required.

ICGOODFIND: The Microchip 24LC16B-E/SN is an exceptional serial EEPROM, delivering a reliable combination of low-power operation, a robust communication interface, and flexible memory organization in a compact package, making it an ideal solution for diverse embedded design needs.
