What are the key features of 24LC64T-I/MC?
- 64 Kbit (8K x 8) I2C EEPROM with 400 kHz fast-mode support for high-throughput embedded storage
- 1,000,000 write/erase cycle endurance with 200-year minimum data retention for long-life applications
- Ultra-compact 8-pin 2x3 DFN package enabling dense PCB integration in space-constrained IoT devices
What is 24LC64T-I/MC used for?
24LC64T-I/MC is widely used for non-volatile parameter storage in microcontroller-based systems including IoT sensors, industrial PLCs, and consumer electronics that require persistent configuration data. Its I2C interface with hardware address pins allows up to 8 devices on a single 2-wire bus, making it efficient for multi-EEPROM systems storing calibration tables or firmware parameters. The compact DFN package and low operating voltage range also suit wearable devices and battery-powered data loggers.

Frequently Asked Questions
How many 24LC64T-I/MC devices can share a single I2C bus without additional logic?
Up to 8 devices can share a single I2C bus simultaneously by setting the 3 hardware address pins (A0, A1, A2) to unique binary combinations. This allows 8 × 8 KB = 64 KB of total addressable EEPROM on one 2-wire bus, which is sufficient for storing multiple configuration tables, calibration coefficients, and event logs in embedded systems without adding a bus expander.
For an industrial sensor that writes calibration data daily, how long will 24LC64T-I/MC last under continuous write cycling?
With 1,000,000 write/erase cycle endurance, a sensor writing calibration data once per day would reach end-of-life in approximately 2,740 years, far exceeding any realistic product lifespan. For more aggressive duty cycles such as 100 writes per day, the endurance spans roughly 27 years, well beyond the 200-year minimum data retention period guaranteed by Microchip.
What read access time does 24LC64T-I/MC provide and does it suit real-time control loops?
24LC64T-I/MC delivers a 900 ns random read access time at the device level, but I2C transactions include address framing overhead, so effective byte read latency at 400 kHz fast mode is approximately 20 µs to 50 µs. This latency is acceptable for initialization and parameter loading but too slow for cycle-by-cycle real-time control loops running above 10 kHz; those applications should cache data in microcontroller RAM after a single EEPROM read at startup.
