What are the key features of 24LC01B-I/MS?
- 1 Kbit I2C EEPROM with 400 kHz fast-mode bus support and hardware write-protect for safe non-volatile data storage in 8-pin MSOP
- 1,000,000 write/erase cycle endurance with 200-year minimum data retention ensuring long-service-life embedded memory
- Wide supply voltage range of 1.8 V to 5.5 V enables direct use with 1.8 V, 3.3 V, and 5 V microcontroller systems without level shifting
What is 24LC01B-I/MS used for?
24LC01B-I/MS is ideal for storing small amounts of calibration data, configuration parameters, and device identifiers in IoT sensors, wearables, and industrial meters operating from 1.8 V to 5.5 V. Its tiny 8-pin MSOP footprint and I2C interface with a single control byte (1010XXXR) make it easy to integrate into space-constrained PCBs alongside microcontrollers.

Frequently Asked Questions
How many write cycles does the 24LC01B-I/MS support and how long will stored data last?
The 24LC01B-I/MS is rated for 1,000,000 write/erase cycles per byte and guarantees a minimum data retention time of 200 years, making it reliable for applications that repeatedly update calibration or configuration values over the product lifetime.
What supply voltage range does 24LC01B-I/MS accept, and at what I2C clock speed does it operate?
The device operates from 1.8 V to 5.5 V and supports I2C clock frequencies up to 400 kHz in fast mode, allowing it to interface directly with 1.8 V, 3.3 V, and 5 V microcontrollers without additional level-shifting circuitry.
For a compact wearable design, how does the MSOP-8 package of 24LC01B-I/MS compare to the standard SOIC-8?
The MSOP-8 package used by 24LC01B-I/MS has a footprint of approximately 3 mm x 3 mm, roughly 50% smaller than an SOIC-8 footprint of about 5 mm x 4 mm, providing significant PCB space savings in wearable and miniaturized IoT products while retaining the same 1 Kbit I2C functionality.
