Connect to the positive supply voltage (usually 2.5V to 5.5V).Circuit Principle and Usage
Power Supply (VCC and GND): The VCC pin must be connected to a stable power supply between 2.5V and 5.5V. The GND pin must be connected to the ground of the system. I2C Communication (SDA and SCL): This EEPROM uses the I2C protocol for communication. The SDA (Serial Data) pin is the bidirectional data line, while the SCL (Serial Clock) pin provides the clock for data transmission. These lines must be pulled up to the supply voltage with resistors. Address Pins (A0, A1, A2): These pins are used to set the device address. By connecting them to ground or VCC, the device address can be configured. Multiple devices can be connected to the same I2C bus by assigning different addresses to each. Write Protect (WP): This pin prevents writing to the EEPROM when it is tied to a high voltage level. If this pin is grounded, write operations are enabled.Frequently Asked Questions (FAQs) for M24C02-RMN6TP
