Key Features
- 1 kbit I2C EEPROM with 400 kHz Fast-mode compatible interface enabling easy integration with any I2C microcontroller
- 1,000,000 write/erase cycle endurance and 200-year minimum data retention for long-life configuration storage
- RoHS-compliant 8-pin SOIC package (JESD-30 R-PDSO-G8) supporting standard SMT reflow assembly in space-constrained designs
Applications
The 24AA014-I/SN is suited for storing calibration constants, user preferences, and system configuration parameters in low-power embedded designs such as sensor nodes, wearable devices, and IoT edge controllers. Its 1 kbit capacity and 400 kHz I2C interface make it a simple plug-in companion to PIC, AVR, ARM, or any I2C-equipped microcontroller. The high endurance of 1 million cycles also supports frequent firmware-controlled log or event count updates without premature wear.

Frequently Asked Questions
How many write/erase cycles can the 24AA014-I/SN endure before reliability degrades?
The 24AA014-I/SN is rated for a minimum of 1,000,000 write/erase cycles per byte location, ensuring reliable operation even in applications that update stored parameters frequently, such as event counters or runtime calibration values in industrial sensor modules over multi-year deployments.
What I2C clock speed does the 24AA014-I/SN support, and which address pins configure its bus address?
The 24AA014-I/SN supports a maximum I2C clock frequency of 400 kHz (Fast-mode), and its 7-bit device address is partially set by two hardware address pins (A1, A0), allowing up to 4 devices on the same I2C bus using the control byte format 1010DDDR. This enables multi-device EEPROM arrays sharing a single 2-wire bus.
For how long can the 24AA014-I/SN retain stored data without power, and what does that mean for end-product lifetime?
The 24AA014-I/SN guarantees a minimum data retention period of 200 years at room temperature under standard operating conditions, far exceeding typical product lifespans of 10 to 20 years. This makes it a dependable choice for storing factory calibration, serial numbers, and firmware version data that must survive power removal in field-deployed equipment.
Is the 24AA014-I/SN a suitable drop-in replacement for other 1 kbit I2C EEPROMs from competing manufacturers?
The 24AA014-I/SN is pin-compatible and protocol-compatible with 1 kbit I2C EEPROMs using the standard 1010xxx device address scheme and the 8-pin SOIC footprint, such as the AT24C01C from Microchip or equivalent parts from ON Semiconductor and STMicroelectronics. Verify write-cycle timing (1 ms page-write time) and maximum clock (400 kHz) match the target part's datasheet before substituting in production.
