M24C02-RMN6TP 概覽
An EEPROM (Electrically Erasable Programmable Read-Only Memory) is a non-volatile memory type that retains data when power is removed, allowing byte-level erasure and reprogramming electrically. In the memory hierarchy, EEPROM sits between volatile RAM and read-only ROM, providing flexible storage for configuration parameters, calibration data, and small application logs. It is a fundamental building block in embedded systems, often interfaced via standard serial protocols like I2C or SPI.
Key features include a wide operating voltage range (1.8V to 5.5V) that supports both 3.3V and 5V logic systems, a 400 kHz I2C interface for fast data transfer, and a 5 ms write cycle time for efficient programming. The device also offers a write protect pin to prevent accidental data corruption, and a page write capability of 16 bytes, enhancing programming efficiency. Its low-power consumption makes it suitable for battery-operated devices.
The M24C02-RMN6TP uses a standard I2C protocol with a 7-bit device address, allowing up to eight devices on the same bus. It features a self-timed write cycle with auto-erase, simplifying the programming sequence. The device is manufactured using ST's advanced CMOS technology, ensuring high reliability and endurance of 1 million write cycles, with data retention of 40 years.
Typical applications include storing calibration data in industrial sensors, configuration parameters in smart meters, and device settings in consumer electronics such as TVs and set-top boxes. Its small SOIC-8 footprint and wide voltage range make it ideal for space-constrained designs.
When designing with this device, ensure proper pull-up resistors on the SDA and SCL lines (typically 4.7kΩ for 400 kHz operation) and connect the write protect pin to ground when writing is required. The device supports both byte and page write modes, with page size of 16 bytes, and acknowledges each byte during programming.

- Industrial temperature range (對比M24C02-RMN6TP (commercial grade))
設計說明
Place pull-up resistors (typically 4.7kΩ) on the SDA and SCL lines for I2C communication. For 400 kHz operation, ensure the bus capacitance does not exceed 400 pF. Keep traces short and avoid routing near high-noise sources. Connect the WC pin to ground for normal write operations, or to VCC to enable write protection.
Decouple the VCC pin with a 0.1µF ceramic capacitor placed as close as possible to the device. The M24C02-RMN6TP operates from 1.8V to 5.5V, so ensure the supply voltage is within this range. For battery-powered applications, the low standby current (typically 1µA) helps extend battery life.
Ensure the device address pins (A0, A1, A2) are correctly tied to VCC or GND to avoid address conflicts on the I2C bus. The M24C02 uses a 7-bit address with the upper 4 bits fixed as 1010, and the lower 3 bits set by A0-A2. Incorrect address settings will prevent communication with the device.
