The diagram below can be referred to as the pinout and the connections of 24C64 to an MCU/MPU. The 24C64 communicates via the I2C bus, so the SDA and the SCL pins are connected to the Data (I2C SDA) and clock(I2C SCK) line pin of the MCU/MPU, respectively. The SCA and SDA pins on the device are open rails so to make it work as normal pins you can also connect the pins to a pull-up resistor of 4.7K ohm and connect it to the VCC and then connect to your MCU. The 3 pins A0, A1, and A2 form the address, so can be put to the ground. The WP/WC pin can be pulled down to the ground and the VCC and GND terminal of the 24C64 IC is to
