Frequently Asked Questions
What read and write access speeds does M24C64-FMN6TP/B support over its I2C bus?
The M24C64-FMN6TP/B supports I2C Fast mode at up to 400 kHz clock frequency, allowing rapid sequential reads of all 8192 bytes. Standard mode at 100 kHz is also supported, giving designers flexibility in noise-sensitive environments where slower bus speeds reduce EMI.
How long can M24C64-FMN6TP/B retain stored data without power, and how many rewrites does it tolerate?
The device is specified for 40-year data retention without power and supports at least 1 million write cycles per byte address. This makes it reliable for applications such as industrial calibration records and odometer logging where data integrity over a long product lifetime is critical.
Over what supply voltage range can M24C64-FMN6TP/B operate, and does it require level shifting on a 3.3 V system?
The M24C64-FMN6TP/B operates from 2.5 V to 5.5 V, so it connects directly to 3.3 V microcontroller I2C buses without a level shifter. For 5 V systems such as legacy 8-bit MCU designs, no additional power rail conversion is needed, simplifying the BOM.
How does the hardware write-protect pin help safeguard critical firmware configuration bytes from accidental overwrite?
Pulling the WC (Write Control) pin high disables all write operations to the entire 64 Kbit array, acting as a hardware lock independent of software. This 1-pin protection mechanism ensures that even a runaway firmware loop writing to address 0x0000 cannot corrupt stored calibration or security keys.
