Key Features
- 16Kbit (2K x 8) I2C serial EEPROM operating from as low as 1.8V supply for ultra-low-power battery-operated designs
- Standard SOIC-8 package with matte tin finish rated for 260°C peak reflow temperature, compatible with lead-free assembly processes
- 2-wire I2C interface simplifies firmware integration and minimizes pin usage compared to parallel or SPI NOR Flash alternatives
Applications
The 24AA16-I/SN is well-suited for storing calibration constants, configuration parameters, and small firmware patches in microcontroller-based sensor nodes, IoT devices, and industrial instruments operating at 1.8V to 5.5V. Its 2K x 8 byte-addressable EEPROM organization and standard I2C interface make it a drop-in non-volatile storage solution for systems that require frequent small-block write operations over the product's lifetime.

Frequently Asked Questions
What is the storage capacity of 24AA16-I/SN, and at what minimum voltage does it operate?
The 24AA16-I/SN provides 16Kbits of EEPROM storage organized as 2048 x 8 bytes, making it suitable for configuration tables, calibration coefficients, and device ID storage. It operates from a minimum supply voltage of 1.8V, which is compatible with modern low-power microcontrollers and SoCs that run on 1.8V or 2V rails.
Which embedded applications commonly rely on the 24AA16-I/SN for non-volatile parameter storage?
The 24AA16-I/SN is widely used in sensor modules, smart meters, and IoT end-nodes to retain 16Kbits of calibration data, network keys, and user settings across power cycles. Its 2-wire I2C interface requires only 2 signal lines, preserving GPIO pins on pin-limited microcontrollers in compact embedded designs.
What peak reflow temperature does 24AA16-I/SN support, and how does that affect PCB assembly compatibility?
The 24AA16-I/SN withstands a peak reflow temperature of 260°C, meeting the JEDEC J-STD-020 standard for lead-free solder assembly. Its matte tin terminal finish and SOIC-8 package are fully compatible with standard SMT pick-and-place and reflow soldering lines used in industrial and consumer electronics manufacturing.
