What are the key features of 24LC014H-I/ST?
- 1 Kbit (128 × 8) density in an 8-pin TSSOP for ultra-compact non-volatile storage in space-critical designs
- Up to 1 MHz I2C clock frequency enables fast sequential reads in microcontroller and sensor hub applications
- 1,000,000 write/erase cycle endurance and 200-year data retention ensure long-term reliability in industrial equipment
- 2.5 V to 5.5 V wide supply range allows direct use across 3.3 V and 5 V system buses without level shifting
What is 24LC014H-I/ST used for?
The 24LC014H-I/ST is ideal for storing calibration constants, configuration parameters, and small data tables in microcontroller-based industrial sensors and consumer electronics. Its 1 MHz I2C interface integrates directly with virtually any MCU I2C bus, making it popular for EEPROM-based ID storage in smart meters and medical monitoring devices. The compact 8-pin TSSOP package and 2.5 V to 5.5 V supply range also suit battery-powered IoT nodes where board space and power budget are tightly constrained.

Frequently Asked Questions
How many write/erase cycles can the 24LC014H-I/ST endure before data integrity is at risk?
The 24LC014H-I/ST is rated for 1,000,000 write/erase cycles per byte location, which at a typical embedded logging rate of 10 writes per day translates to roughly 274 years of endurance. Pair this with its minimum 200-year data retention and the device is well suited for lifetime-critical industrial calibration storage.
Which I2C clock rates does the 24LC014H-I/ST support, and how does that affect communication with common 8-bit MCUs?
The device supports standard-mode (100 kHz) and fast-mode (400 kHz) I2C as well as a 1 MHz high-speed mode, covering all popular clock settings on 8-bit PIC, AVR, and STM8 microcontrollers. Running at 400 kHz, a full 128-byte sequential read of the 1 Kbit array completes in under 3 ms, which is fast enough for power-on calibration loads in real-time control loops.
For a 3.3 V IoT sensor node with limited PCB space, how does the TSSOP-8 package of the 24LC014H-I/ST help system integration?
The 8-pin TSSOP footprint measures just 3 mm × 4.4 mm with 0.65 mm lead pitch, occupying under 14 mm² of board area—roughly 40% less than an equivalent DIP-8 part. Operating at 3.3 V within the 2.5 V to 5.5 V supply range, the 24LC014H-I/ST connects directly to a 3.3 V MCU I2C bus with no level translators, saving 2 additional components in a compact IoT sensor node design.
