Key Features
- 2 Kbit (256-byte) I2C EEPROM with 400 kHz Fast Mode bus speed enables rapid configuration data storage in constrained microcontroller systems
- 1.8 V to 5.5 V supply range allows direct interfacing with both 3.3 V and 5 V MCU platforms without level shifting
- 1 million write/erase cycle endurance combined with 200-year data retention supports long-life industrial and consumer product designs
Applications
The 24LC02BT-I/SN is widely used to store small configuration tables, calibration coefficients, and device identity data in embedded systems. It integrates with any I2C master microcontroller operating at 1.8 V to 5.5 V, making it suitable for sensor modules, smart home appliances, and industrial control boards where a few hundred bytes of non-volatile storage are sufficient. The SOIC-8 package and low pin count simplify PCB layout for space-constrained IoT and wearable device applications.

Frequently Asked Questions
How fast can 24LC02BT-I/SN transfer data over I2C, and does that speed suit real-time sensor calibration reads?
24LC02BT-I/SN supports I2C Fast Mode at 400 kHz, allowing a full 256-byte page read in under 6 ms. This speed is more than adequate for reading sensor calibration tables at system startup or during infrequent recalibration events, making the part a cost-effective choice for temperature sensors, pressure transducers, and load cell interfaces that store 16-bit or 24-bit offset and gain coefficients.
What endurance and data retention specs make 24LC02BT-I/SN suitable for frequently updated configuration storage?
The 24LC02BT-I/SN is rated for 1 million write/erase cycles per byte location and a minimum 200-year data retention period at 25°C. For an IoT device writing a new configuration byte once per day, 1 million cycles translates to over 2,700 years of write life, far exceeding any realistic product lifetime and eliminating wear-leveling concerns in small-footprint applications.
Can 24LC02BT-I/SN be used alongside a 3.3 V MCU and a 5 V sensor on the same I2C bus?
Yes. 24LC02BT-I/SN's supply range of 1.8 V to 5.5 V lets it operate at 3.3 V alongside a modern ARM or AVR MCU while still receiving valid logic signals from 5 V TTL-compatible devices on a shared I2C bus with appropriate pull-up resistors. The SOIC-8 package with a 3.9 mm × 4.9 mm body fits easily in mixed-voltage sensor boards where space is limited.
