Overview

The 24LC16BT-I/OT is a 16Kbit I2C serial EEPROM designed for non-volatile storage in space-constrained designs. It operates across a wide voltage range of 2.5V to 5.5V and features an ultra-low standby current of just 1 microamp. This device is organized as eight blocks of 256 x 8-bit memory, accessible via a standard 2-wire serial interface.

Why Choose This Part

The SOT-23-5 package provides a tiny footprint for high-density layouts while maintaining high reliability with over 1 million erase/write cycles and 200-year data retention. Integrated Schmitt Trigger inputs and output slope control improve noise immunity and signal integrity in noisy industrial environments.

Applications

Calibration Data Storage
Storing sensor offset and gain coefficients in industrial instrumentation where data must persist through power cycles.
Device Configuration
Saving user settings, network node addresses, and boot parameters in automotive and consumer electronics.
Event Logging
Recording error codes or usage timestamps in small-scale embedded systems with limited PCB real estate.

Getting Started

To interface with the 24LC16BT-I/OT, connect the SCL and SDA lines to a microcontroller I2C peripheral with external pull-up resistors (typically 4.7k to 10k ohms). Use standard I2C libraries to perform byte or page writes, ensuring a 5ms delay between write operations to allow for the self-timed internal cycle.
