Notes 1. Connect the TEST pin directly to VSS or pull down. For the pull-down connection, use of a resistor whose

resistance is between 470

Ω and 10 kΩ is recommended.

2. Connect the AVDD pin to VDD.

3. Connect the AVSS pin to VSS.

4. The SCL0 and SDA0 pins are incorporated only in the

µPD784218Y.

5. Under development
