Microchip 47L16T-I/ST: A Deep Dive into its 16K I2C Serial EEPROM Memory

In the realm of embedded systems and IoT devices, reliable non-volatile memory is a cornerstone for data storage and configuration. The Microchip 47L16T-I/ST stands out as a robust and efficient solution, offering 16 kilobits (2 Kbytes) of Electrically Erasable Programmable Read-Only Memory (EEPROM). This device is engineered for low-power operation and communicates via the ubiquitous I2C (Inter-Integrated Circuit) serial protocol, making it an ideal choice for a vast array of applications.

A key strength of this memory chip lies in its advanced write-protection schemes. It features both hardware and software data protection mechanisms. The dedicated `WC` (Write Control) pin allows designers to implement hardware-level protection to prevent inadvertent writes, securing critical data. Furthermore, the device supports sequential read operations, enabling efficient data streaming and significantly improving overall system performance compared to single-byte reads.

The 47L16T-I/ST is designed for exceptional reliability and endurance, capable of supporting over 1 million erase/write cycles. Its data retention period exceeds 200 years, ensuring long-term integrity of stored information. Operating from a wide voltage range (1.7V to 5.5V), it is perfectly suited for both battery-powered and mains-connected devices, from smart sensors and medical instruments to industrial controls and consumer electronics. Its space-saving TSSOP package further aids in designing compact and efficient PCBs.

ICGOODFIND: The Microchip 47L16T-I/ST is a highly reliable, low-power, and compact 16K I2C Serial EEPROM. Its combination of robust data protection, high endurance, and a wide operating voltage range makes it an exceptional memory solution for modern electronic designs where data integrity and power efficiency are paramount.
