Overview

The 24LC16B-I/P is a 16-Kbit I2C serial EEPROM designed for low-power applications with a wide operating voltage range from 2.5V to 5.5V. It is organized as eight blocks of 256 bytes, providing a total of 2048 bytes of non-volatile storage for configuration data or user settings. The 8-pin PDIP package makes it an ideal choice for prototyping and through-hole assembly in industrial and consumer designs.

Why Choose This Part

The device features a low standby current of only 1 uA and an active run current of 3mA, making it suitable for battery-powered devices. Its I2C interface supports clock frequencies up to 400 kHz, allowing for reliable communication with most modern microcontrollers using just two signal lines.

Applications

Microcontroller Configuration Storage
Storing boot-up parameters, calibration constants, and user preferences in embedded systems.
Industrial Data Logging
Recording error logs or operational statistics in equipment where power might be cycled frequently.
Breadboard Prototyping
Providing non-volatile memory for development projects using the standard 2.54mm pitch through-hole format.

Getting Started

Connect the VCC pin to a 2.5V to 5.5V supply and the GND pin to system ground, ensuring a 0.1uF decoupling capacitor is placed nearby. Use a microcontroller with an I2C peripheral and 4.7k ohm pull-up resistors on the SDA and SCL lines to begin reading and writing to the 2048 available memory bytes. For rapid prototyping, this PDIP version fits directly into standard solderless breadboards or 8-pin DIP sockets.
