What are the key features of 24LC02B-I/MS?
- 2 Kbit (256-byte) EEPROM capacity with 400 kHz I2C fast-mode interface for reliable non-volatile data storage in microcontroller-based systems
- 2.5 V to 5.5 V wide supply range supporting both 3.3 V and 5 V microcontrollers without level shifting or separate voltage regulation
- Compact 8-pin MSOP package enabling high-density PCB placement in space-constrained IoT nodes and wearable device designs
What is 24LC02B-I/MS used for?
The 24LC02B-I/MS is designed for storing small amounts of non-volatile configuration data, calibration coefficients, and device identifiers in embedded systems with an I2C bus. It is commonly used in sensor modules, smart meter end-points, and consumer electronics to retain factory trim values and user settings across power cycles. Its tiny 8-pin MSOP footprint and wide supply range make it straightforward to integrate alongside 3.3 V or 5 V microcontrollers in compact IoT and wearable applications.

Frequently Asked Questions
How much data can the 24LC02B-I/MS store, and how is the memory organized?
The 24LC02B-I/MS provides 2 Kbits of EEPROM organized as a single 256-byte address space accessible over the I2C bus, with an 8-byte page write buffer that allows up to 8 bytes to be written in a single write cycle, reducing total write time when updating consecutive memory locations.
What I2C clock speed does the 24LC02B-I/MS support, and how does that affect write latency?
The device supports the I2C fast mode up to 400 kHz, enabling a full-page 8-byte write command to complete in less than 200 µs of bus time, followed by a self-timed internal write cycle of maximum 5 ms, which is fast enough for configuration updates in real-time embedded control loops.
How many write cycles can the 24LC02B-I/MS endure before wear affects data retention?
The 24LC02B-I/MS is rated for a minimum of 1,000,000 byte or page write cycles per memory location, and retains data for a minimum of 200 years at room temperature, making it reliable for configuration storage in products with infrequent writes but long service life such as smart utility meters.
Can the 24LC02B-I/MS share an I2C bus with other EEPROM devices without address conflict?
Yes, the 24LC02B has 3 hardware address pins (A0, A1, A2) allowing up to 8 unique 7-bit I2C addresses on the same bus, so up to 8 devices totaling 16 Kbits of EEPROM storage can coexist on a single 2-wire I2C bus without any address conflict.
How does the 8-pin MSOP package of the 24LC02B-I/MS compare in size to a standard SO-8?
The 8-pin MSOP measures approximately 3.0 mm × 4.9 mm with a 0.65 mm pin pitch, versus roughly 5.3 mm × 6.2 mm for a standard SO-8, making the MSOP about 45% smaller in board area and preferable for compact designs where PCB real estate is limited such as sensor breakout boards and wearable modules.
