Microchip 47L16-E/SN: 16-Kbit Serial I²C EEPROM for Low-Voltage Applications

In the realm of embedded systems and IoT devices, efficient and reliable non-volatile memory is essential for storing configuration data, calibration constants, or user settings. The Microchip 47L16-E/SN stands out as a robust 16-Kbit Serial I²C EEPROM specifically engineered for low-voltage applications, making it an ideal choice for power-sensitive designs.

This device operates seamlessly within a voltage range of 1.7V to 3.6V, catering to modern microcontrollers and systems powered by batteries or energy harvesting sources. Its I²C-compatible interface ensures easy integration with a vast array of host controllers, supporting communication speeds up to 1 MHz. The EEPROM is organized as 2048 x 8 bits, providing ample storage while maintaining a compact footprint with its 8-lead SOIC package.

Key features include hardware write-protection via the WC (Write Control) pin, safeguarding critical memory regions from unintended modifications. It also boasts high endurance, supporting up to 1 million erase/write cycles, and data retention of over 200 years, ensuring long-term reliability. With a typical active current consumption of 1 mA at 1 MHz and a standby current of just 1 μA, the 47L16-E/SN excels in power efficiency.

Designed for industrial and automotive temperature ranges (-40°C to +125°C), it meets stringent operational demands. Applications span from smart sensors and wearables to automotive modules and industrial controls, where low-voltage operation and minimal power consumption are paramount.
