Key Features
- 1 Kbit (128 bytes) I2C EEPROM with 400 kHz fast-mode bus for simple configuration storage in small microcontroller designs
- 1 million write/erase cycle endurance and 200-year minimum data retention for lifetime calibration data storage
- 900 ns read access time enabling rapid data retrieval after power-on initialization sequences
- 8-pin PDIP through-hole package with I2C address pins A0–A2 allowing up to 8 devices on a shared 2-wire bus
Applications
The 24LC014-I/P stores small configuration records, device serial numbers, and calibration constants in microcontroller-based consumer electronics, appliances, and industrial sensors. Its 1 Kbit capacity suits applications where only a few bytes to 128 bytes of non-volatile data are needed, minimizing cost and PCB footprint. The 400 kHz I2C interface enables direct connection to virtually any MCU with a hardware I2C peripheral, requiring only a 2-wire SDA/SCL connection and two pull-up resistors.

Frequently Asked Questions
How much data can the 24LC014-I/P store and how quickly can it be read back over I2C at 400 kHz?
The 24LC014-I/P stores 128 bytes (1 Kbit) of non-volatile EEPROM data accessible at 400 kHz I2C clock speed with a 900 ns read access time. Reading all 128 bytes sequentially takes approximately 2.6 ms at 400 kHz, fast enough for power-on configuration loading in embedded systems requiring immediate access to stored parameters.
For a calibrated temperature sensor design, how does 24LC014-I/P's 1 million cycle endurance support factory and field calibration workflows?
With 1 million write/erase cycles at 8-byte page granularity, the 24LC014-I/P supports factory calibration writes during production plus up to 1000 field recalibrations per year for 1000 years of service, far exceeding realistic product lifetimes. The 200-year minimum data retention at 25°C ensures calibration coefficients stored at factory remain readable throughout the sensor's 10–20 year service life.
How many 24LC014-I/P devices can share a single I2C bus and what addressing scheme do they use?
Up to 8 units of 24LC014-I/P can share one I2C bus using the 3-bit device address pins A0, A1, and A2 in the control byte format 1010DDDR. Wiring each device to a unique A0–A2 combination gives 8 independent 128-byte EEPROM banks totaling 1024 bytes on a single 2-wire SDA/SCL bus, useful for distributed configuration storage in multi-node sensor networks.
When is the 24LC014-I/P 1 Kbit capacity the right size and when should engineers select a larger I2C EEPROM?
The 24LC014-I/P is the right fit when storing fewer than 100 bytes of device parameters such as a 4-byte serial number, 10-byte calibration coefficients, and a 16-byte configuration record at lowest BOM cost. Engineers should upgrade to 24LC256 (32 KB) or larger when data logs, firmware images, or multi-parameter look-up tables exceed 128 bytes, as the 24LC014 has no provision for expanding storage beyond its 1 Kbit density.
