Notes 1.

SDA0 and SCL0 are incorporated only in the

µPD78F0034BY, 78F0034BY(A) Subseries.

SI31, SO31, and SCK31 are incorporated only in the

µPD78F0034B, 78F0034B(A) Subseries.

Cautions 1. Connect the VPP pin directly to VSS0 or VSS1 in normal operation mode.

2. Connect the AVSS pin to VSS0.

Remark

When the

µPD78F0034B, 78F0034BY, 78F0034B(A), and 78F0034BY(A) are used in application fields

that require reduction of the noise generated from inside the microcontroller, the implementation of noise

reduction measures, such as supplying voltage to VDD0 and VDD1 individually and connecting VSS0 and

VSS1 to different ground lines, is recommended.
