Applications
The 24LC02BT-I/OT is well suited for storing calibration data, configuration parameters, and user preferences in consumer electronics and industrial equipment. Its low-voltage operation makes it ideal for battery-powered devices such as wearables, smart meters, and handheld instruments. The compact SOT-23-5 footprint and I2C interface also suit it for PCB designs where board space is limited and minimal pin count is required.

Frequently Asked Questions
What supply voltage range does the 24LC02BT-I/OT support, and how does that affect system design?
The 24LC02BT-I/OT operates from 2.5V to 5.5V, making it compatible with both 3.3V and 5V logic systems without additional level translation. This wide voltage range simplifies integration into mixed-voltage designs and supports battery-powered applications down to 2.5V, extending usable battery life.
How fast can the 24LC02BT-I/OT write data, and what is the page write size?
The device supports 400 kHz fast-mode I2C operation and an 8-byte page write buffer. A single page write completes within a 5 ms write cycle time, allowing firmware to write up to 8 bytes per transaction. For designs requiring frequent sequential writes, using the page write mode significantly improves throughput compared to byte-by-byte operations.
Which compact package does the 24LC02BT-I/OT use, and how does it compare to a DIP alternative?
The part comes in a SOT-23-5 package measuring approximately 2.9 mm x 1.6 mm, which is far smaller than an 8-pin DIP. The 5-pin SOT-23 occupies under 5 mm² of board area, making it the preferred choice for space-constrained PCBs such as wearable sensors or IoT edge nodes where every square millimeter counts.
What is the endurance and data retention specification for the 24LC02BT-I/OT?
The 24LC02BT-I/OT is rated for at least 1,000,000 erase/write cycles per byte and guarantees data retention of 200 years at 25°C. These specifications make it reliable for storing configuration data that is updated frequently, such as calibration offsets written hundreds of thousands of times over a product's service life.
