Frequently Asked Questions
What I2C clock speed and supply voltage does the 24LC01B-I/SN support?
It operates on a 2-wire I2C bus at clock speeds up to 400 kHz and accepts a wide 2.5 V to 5.5 V supply, making it suitable for both 3.3 V and 5 V embedded designs.
How many write cycles and how long does stored data stay valid in this EEPROM?
The 24LC01B-I/SN is rated for 1,000,000 erase/write cycles per cell and retains stored data for more than 200 years, so it comfortably handles frequent logging of calibration or configuration values.
Is the SOIC-8 industrial-grade version suitable for harsh-temperature boards?
Yes. The I/SN suffix denotes an industrial grade rated from -40C to +85C in an 8-lead SOIC package, and the part is RoHS-compliant and lead-free for standard reflow assembly.
What is a pin-compatible alternative if the 24LC01B-I/SN is on long lead time?
The 24AA01-I/SN (1.7 V to 5.5 V) and the higher-density 24LC02B (2 Kbit) are pin-compatible 8-SOIC options on the same I2C bus; confirm the 128 x 8 density and 400 kHz speed fit your design first.
