M24C08-RMN6TP 概要
An EEPROM (Electrically Erasable Programmable Read-Only Memory) is a non-volatile memory that can be electrically erased and reprogrammed, retaining data without power. It is a type of memory IC that falls under the broader category of non-volatile memory, which also includes flash memory and MRAM. EEPROMs are used for storing configuration parameters, calibration data, device IDs, and small amounts of firmware that require in-system updates. The M24C08 is part of the M24Cxx family of serial EEPROMs, which are widely used in industrial, automotive, and consumer electronics.
Key features of the M24C08-RMN6TP include a byte-write time of 5 ms, a write cycle endurance of 1 million write cycles, and a data retention of 40 years. The device supports both byte and page write modes (up to 16 bytes per page), and sequential read operations. It also includes a write protect (WC) pin that, when tied high, prevents write operations to the entire memory array. The device is available in a standard SOIC-8 package, which is pin-compatible with many other 8-pin EEPROMs, allowing easy drop-in replacement.
The M24C08 uses a standard I2C interface with a 2-wire serial bus (SCL and SDA), and supports 7-bit device addressing with three address pins (A0, A1, A2) allowing up to eight devices on the same bus. The device is designed for low-power operation, with a standby current of 1 uA and a maximum active current of 2 mA at 400 kHz. It operates over a temperature range of -40C to +85C, making it suitable for industrial environments.
Typical applications include storing calibration data in sensors, configuration settings in set-top boxes, device parameters in smart meters, and system logs in industrial controllers. The M24C08 is also used in automotive electronics for storing VIN numbers, tire pressure monitoring system (TPMS) data, and infotainment system settings.
When designing with the M24C08, ensure that the SDA and SCL lines have appropriate pull-up resistors (typically 4.7 kOhm) and that the write protect pin is connected to a defined logic level. The device supports I2C fast mode (400 kHz) and is compatible with standard mode (100 kHz). For reliable operation, decouple the VCC pin with a 0.1 uF ceramic capacitor close to the device.

設計ノート
Place a 0.1 uF ceramic decoupling capacitor as close as possible to the VCC pin (pin 8) and GND (pin 4) to filter high-frequency noise. For I2C lines, use pull-up resistors (typically 4.7 kOhm) to VCC. The pull-up values may need adjustment based on bus capacitance and speed. Ensure the SDA and SCL traces are kept short and away from high-noise sources.
Do not leave the WC (write protect) pin floating; tie it to GND for normal write operations or to VCC to protect the memory. Ensure the device address pins (A0, A1, A2) are connected to defined logic levels (GND or VCC) to avoid address conflicts on the I2C bus. Also, verify that the I2C bus speed does not exceed 400 kHz to ensure reliable communication.
The M24C08-RMN6TP has a maximum active current of 2 mA at 400 kHz. During write operations, the current may spike; ensure the power supply can handle transient loads. The standby current is only 1 uA, making it suitable for battery-powered applications. Use a low-dropout regulator if the supply voltage is near the minimum operating voltage to maintain stable operation.
