Applications
The 24LC024T-E/MC is widely used in consumer electronics, industrial sensors, and IoT edge devices for storing calibration data, configuration parameters, and firmware settings that must survive power cycles. Its I2C interface with 400 kHz fast-mode makes it easy to integrate alongside microcontrollers and sensor ICs on shared two-wire buses. The tiny 2x3 mm DFN footprint and low power consumption make it an excellent choice for battery-powered wearables and handheld instruments.

Frequently Asked Questions
What is the maximum I2C clock speed supported by the 24LC024T-E/MC and how does it affect throughput?
The 24LC024T-E/MC supports I2C fast-mode at up to 400 kHz clock frequency, enabling a sequential byte read rate well suited for small parameter tables. The 900 ns maximum read access time ensures reliable operation on standard 3.3 V and 5 V microcontroller buses without wait states.
How many write cycles can the 24LC024T-E/MC endure before data integrity is at risk?
The 24LC024T-E/MC is rated for a minimum of 1,000,000 write/erase cycles per memory location, with a minimum data retention time of 200 years under standard conditions. This makes it well-suited for applications that update configuration data or log counters frequently over the product lifetime.
Which supply voltage range does the 24LC024T-E/MC support, and is it compatible with 3.3 V systems?
The 24LC024T-E/MC operates from 1.7 V to 5.5 V, making it fully compatible with both 3.3 V and 5 V system rails. This wide range allows direct interfacing with low-power microcontrollers and single-cell lithium battery systems without level-shifting hardware.
What is the physical package size of the 24LC024T-E/MC and how does it benefit compact PCB layouts?
The 24LC024T-E/MC is available in an 8-pin DFN package measuring 2x3 mm, one of the smallest footprints for serial EEPROM devices. This compact size reduces PCB area requirements in wearable devices, IoT sensors, and space-constrained industrial modules compared to traditional 8-SOIC alternatives.
How is hardware write protection implemented on the 24LC024T-E/MC?
The 24LC024T-E/MC includes a dedicated WP (Write Protect) pin that, when driven high, prevents any write operations to the entire 256-byte array. This hardware mechanism protects critical calibration or configuration data stored at the factory from accidental overwrite during normal system operation at 1.7 V to 5.5 V.
