Applications
The M24C64-DRMN8TP/K is deployed in automotive ECUs and dashboard modules to store calibration tables, configuration parameters, and event logs that must survive 105°C engine-bay temperatures. It serves industrial PLC and sensor modules requiring non-volatile parameter backup across power cycles, where I2C simplifies wiring to host microcontrollers. Its 8 Kbyte capacity and hardware address pins enable multi-device bus configurations for systems that need distributed non-volatile storage across multiple subsystem boards.

Frequently Asked Questions
What I2C clock frequencies does the M24C64-DRMN8TP/K support and what is its page write buffer size?
The M24C64-DRMN8TP/K operates at standard 100 kHz, fast 400 kHz, and fast-mode plus 1 MHz I2C clock rates. Its internal page write buffer holds 32 bytes, allowing up to 32 bytes to be written in a single I2C transaction with a 5 ms typical write cycle time, which is faster than byte-by-byte writes for bulk configuration uploads.
How many M24C64-DRMN8TP/K devices can share a single I2C bus and how is addressing configured?
Up to 8 M24C64-DRMN8TP/K devices share a single I2C bus by setting unique 3-bit addresses through the A0, A1, and A2 hardware pins connected to VCC or GND. This allows 8 × 8 Kbyte = 64 Kbyte of total non-volatile storage accessible from one microcontroller I2C port, suitable for modular expansion cards and multi-sensor logging systems.
What write endurance and data retention does the M24C64-DRMN8TP/K guarantee for automotive applications?
The device is specified for 4 million write cycles per byte, far exceeding the 1 million cycle minimum required by most automotive EEPROM specifications. Data retention is guaranteed for 200 years at 55°C and over 40 years at 85°C, ensuring that calibration data written during vehicle manufacturing remains intact throughout the vehicle's operational lifetime.
At what supply voltage range does the M24C64-DRMN8TP/K operate for use in 3.3 V microcontroller designs?
The M24C64-DRMN8TP/K accepts a supply voltage from 1.7 V to 5.5 V, making it directly compatible with 3.3 V microcontroller I/O without level shifting. At 1.8 V supply, it still communicates reliably at 400 kHz, enabling use in ultra-low-power IoT devices where the MCU and memory share a battery-optimized 1.8 V rail.
