Frequently Asked Questions
How many write/erase cycles and how long will data persist in the 24LC64T-I/SNG?
The 24LC64T-I/SNG is rated for 1,000,000 write/erase cycles per byte location and guarantees a minimum data retention period of 200 years, making it suitable for high-frequency parameter update applications such as event counters and calibration record storage.
How many 24LC64T-I/SNG devices can share a single I2C bus in a multi-sensor system?
Up to 8 units of the 24LC64T-I/SNG can be connected on a single I2C bus simultaneously by configuring the 3-bit hardware address pins A0, A1, and A2, providing up to 64 KB x 8 = 512 KB of addressable EEPROM storage at 400 kHz clock frequency.
How does the 24LC64T-I/SNG perform in mixed 3.3 V and 5 V embedded systems?
The 24LC64T-I/SNG operates across a supply voltage range of 1.7 V to 5.5 V, enabling direct interfacing with both 3.3 V MCUs such as ARM Cortex-M devices and 5 V PIC or AVR microcontrollers without level-shifting circuitry on the I2C lines running at up to 400 kHz.
