What are the key features of 24AA02T-I/OT?
- 2 Kbit (256 x 8 bytes) I2C EEPROM with 1.8 V low-voltage operation for integration with modern ultra-low-power MCUs
- Industrial-grade temperature rating in a compact SOT-23 (5-pin) package enabling robust non-volatile storage in space-constrained designs
- Byte and page write capability with hardware write-protect pin for secure configuration data storage in embedded systems
What is 24AA02T-I/OT used for?
The 24AA02T-I/OT is used in embedded systems requiring small-capacity non-volatile configuration or calibration data storage, such as sensor modules, IoT end nodes, and portable medical devices. Its 1.8 V operation and I2C interface make it directly compatible with modern low-power MCUs and BLE SoCs without level translation.

Frequently Asked Questions
What is the storage capacity of the 24AA02T-I/OT EEPROM, and how is it organized?
The 24AA02T-I/OT provides 2 Kbits of EEPROM organized as 256 bytes (256x8 bits). This capacity is sufficient for storing device configuration parameters, calibration coefficients, or unique identifier data in sensor modules, IoT nodes, and industrial instruments communicating via I2C.
What supply voltage does the 24AA02T-I/OT support, and how does this affect compatibility with modern MCUs?
The 24AA02T-I/OT operates at 1.8 V supply voltage, aligning directly with the I/O voltage of modern ultra-low-power MCUs and BLE SoCs such as Nordic nRF52 or STM32L0 series parts that operate at 1.8 V. This eliminates the need for external level shifters and simplifies PCB design in battery-powered embedded systems.
For a calibration data storage application, why would a designer choose the 24AA02T-I/OT SOT-23 package over a larger SOIC-8 EEPROM?
The SOT-23 (5-pin) package of the 24AA02T-I/OT measures only 2.9x1.6 mm, occupying roughly 4x less PCB area than a standard SOIC-8 package. For sensor modules or IoT edge nodes where PCB real estate is at a premium, the SOT-23 form factor allows 2 Kbit non-volatile storage to be added with minimal space impact alongside the main MCU.
