Key Features
- 2 Kbit (256-byte) EEPROM capacity with 1,000,000 write endurance cycles for reliable non-volatile configuration and calibration data storage
- 1.7 V to 5.5 V wide supply voltage operation in 5-pin SOT-23 package enabling use with 1.8 V, 3.3 V, and 5 V microcontroller systems
- I2C fast-mode 1 MHz serial interface with hardware write-protect pin for secure data retention in wearable and IoT sensor nodes
Applications
24FC02T-E/OT is used for non-volatile storage of calibration coefficients, device configuration parameters, and unique serial numbers in IoT sensor nodes, wearable electronics, and portable medical devices. Its 2 Kbit capacity and I2C interface allow a microcontroller to read or update 256 bytes of persistent data at up to 1 MHz bus speed with minimal firmware overhead. The tiny SOT-23-5 package and 1.7 V minimum supply make it ideal for space-constrained, battery-powered designs where a compact non-volatile memory is required alongside a low-power MCU.

Frequently Asked Questions
What is the storage capacity and write endurance of 24FC02T-E/OT, and how does that fit typical IoT configuration needs?
24FC02T-E/OT provides 2 Kbits (256 bytes) of EEPROM storage with a guaranteed write endurance of 1,000,000 cycles. This is sufficient to store 32 to 64 calibration coefficients or configuration registers updated daily for over 2700 years, making it ideal for sensor calibration tables, Wi-Fi credentials, and device serial numbers in IoT edge nodes.
At what I2C bus speed does 24FC02T-E/OT operate, and what supply voltages are compatible?
24FC02T-E/OT supports I2C fast mode at up to 1 MHz clock frequency and operates from a 1.7 V to 5.5 V supply, covering 1.8 V, 2.5 V, 3.3 V, and 5 V logic systems. The wide voltage range means the same 5-pin SOT-23 device works with ultra-low-power ARM Cortex-M0+ MCUs at 1.8 V and with 5 V 8-bit PIC or AVR microcontrollers without any level-shifting circuitry.
For a wearable medical device storing patient calibration data, why is 24FC02T-E/OT a better fit than an onboard flash sector?
24FC02T-E/OT offers 1,000,000 write endurance cycles compared to typically 10,000 cycles for microcontroller internal flash sectors, making it more durable for frequently updated calibration data such as daily sensor offset corrections. The 5-pin SOT-23 package occupies less than 10 mm² of PCB area, and its separate I2C address allows the MCU to access calibration memory independently of program code, improving firmware update safety in battery-powered wearable medical designs.
