Unlocking Efficient Non-Volatile Memory with the Microchip 47L16-E/ST 16Kbit I2C Serial EEPROM

In the realm of embedded systems and IoT devices, the need for reliable, compact, and power-efficient non-volatile memory is paramount. The Microchip 47L16-E/ST stands out as a robust solution, offering 16Kbits of electrically erasable programmable read-only memory (EEPROM) organized as 2K x 8 bits. This serial EEPROM leverages the widely adopted I2C (Inter-Integrated Circuit) protocol, enabling seamless communication with microcontrollers and other peripherals while minimizing pin count and board space.

One of the key advantages of the 47L16-E/ST is its low power consumption, making it ideal for battery-powered applications such as smart sensors, wearables, and portable medical devices. With a standby current of just 1 μA (max) and an active current of 1 mA (max), it ensures extended operational life. Additionally, the chip supports a broad voltage range (1.7V to 5.5V), providing flexibility across diverse system designs.

Data integrity and reliability are reinforced through built-in hardware write protection and a page write buffer that allows up to 16 bytes to be written in a single operation, reducing host processor overhead. The device also features a 1 million erase/write cycle endurance and 200-year data retention, critical for applications requiring frequent updates and long-term deployment.

The 47L16-E/ST operates at speeds up to 400 kHz and is housed in an 8-lead TSSOP package, ideal for space-constrained environments. Its industrial temperature range (-40°C to +85°C) ensures performance under harsh conditions.

ICGOODFIND: The Microchip 47L16-E/ST combines durability, efficiency, and compact form factor, serving as a versatile memory solution for modern electronic designs.
