Frequently Asked Questions
What voltage range does the 24LC02B-I/SN support, and how does it interface with microcontrollers?
The 24LC02B-I/SN operates from 2.5V to 5.5V supply voltage, making it compatible with both 3.3V and 5V microcontrollers via the standard 2-wire I2C interface running up to 400 kHz. It supports hardware address configuration allowing up to 8 devices on a single bus.
How much data can the 24LC02B-I/SN store, and what write endurance does it provide?
This EEPROM stores 2Kbits (256 bytes) organized as 256x8-bit words, sufficient for calibration constants, device settings, or small lookup tables. It guarantees 1 million erase/write cycles per byte and data retention of 200 years at 25°C, providing robust non-volatile storage.
Which embedded designs benefit most from using the 24LC02B-I/SN instead of a larger EEPROM?
Designs that only need to store a handful of configuration bytes — such as sensor calibration offsets, MAC addresses, or trim values — benefit from the 24LC02B's 256-byte capacity in the compact SOIC-8 footprint. Choosing this 2Kbit device over a larger variant saves cost when data requirements stay below 256 bytes and the -40°C to +85°C industrial temperature range covers the application.
