Applications
The 24AA014H-I/MS is suited for storing calibration constants, configuration tables, and trim data in low-voltage sensor modules, wearable medical patches, and IoT end-nodes powered from coin cells or energy harvesters. Its 1.8 V operation and 8-pin MSOP footprint enable compact PCB designs in handheld instruments, smart-label readers, and industrial parameter-logging nodes. The high endurance of 1,000,000 cycles makes it appropriate for frequently updated log buffers in metering and monitoring applications.

Frequently Asked Questions
At what supply voltage does 24AA014H-I/MS operate, and why does that matter for coin-cell designs?
The 24AA014H-I/MS operates from as low as 1.8 V, which is within the usable voltage range of CR2032 coin cells nearing end-of-life. This means the EEPROM can store calibration or configuration data reliably without a voltage regulator or level shifter, saving BOM cost and extending battery runtime in IoT sensor nodes and wearable devices.
How many write cycles can 24AA014H-I/MS endure, and how long is data retained without power?
The 24AA014H-I/MS is rated for 1,000,000 write/erase cycles per byte and a minimum data retention time of 200 years under standard conditions. This combination of high endurance and long retention makes it appropriate for applications that update configuration records frequently, such as smart meters or industrial calibration loggers, without risk of premature cell wear-out.
How many 24AA014H-I/MS devices can share a single I2C bus in a multi-node design?
The I2C control byte format 1010DDDR includes 2 hardware address bits (DD), allowing up to 4 devices to share one I2C bus without address conflict. Combined with the 400 kHz maximum clock frequency and the compact 8-pin MSOP package, this supports multi-channel data-logging boards where several small EEPROMs store independent configuration datasets per sensor channel.
For a compact industrial sensor PCB, how much space does the 24AA014H-I/MS MSOP-8 package require?
The MSOP-8 package measures approximately 3 mm x 3 mm with 0.65 mm pin pitch, occupying roughly 9 mm² of board area. This small footprint is significantly more compact than standard SOIC-8 alternatives, making the 24AA014H-I/MS a strong choice for density-constrained designs such as plug-in sensor modules, medical wearables, or miniature data-logger boards operating at 1.8 V.
