CAT24C16WI-GT3
Overview
The CAT24C16WI-GT3 is a 16-Kbit serial EEPROM from ON Semiconductor that uses the industry-standard I2C interface for non-volatile storage. It provides a small-footprint option for saving configuration, calibration, and small data logs in embedded designs. The device is intended as a drop-in 24C16-class memory for systems that need simple, byte-addressable persistent storage.
Why Choose This Part
Uses the ubiquitous I2C bus, making it compatible with virtually any microcontroller that supports I2C and simplifying board routing and firmware. As a standard 24C16-class EEPROM, it is often a drop-in substitute for other 16-Kbit EEPROMs when sourcing or package changes are needed. The small package and low pin count make it suitable for compact designs where only modest non-volatile storage is required.
Applications
Getting Started
This is a serial EEPROM - no IDE needed. To use it, connect it to an I2C master (microcontroller or SBC) with appropriate pull-up resistors and consult the datasheet for device addressing and timing. For quick experiments, use the Arduino Wire library or Raspberry Pi i2c-tools (i2cdetect/i2cget/i2cset) to probe and read/write the device; remember good PCB practice like a bypass capacitor near the supply pin and correct soldering for the package. Ensure you confirm the device address pins and write-protect options before bringing the bus up.
