Data Sheet U14040EJ4V0DS
1. PIN CONFIGURATION (TOP VIEW)
•
64-pin plastic SDIP (19.05 mm (750))
µPD78F0034ACW, 78F0034AYCW
Notes 1.
SDA0 and SCL0 are incorporated only in the
µPD78F0034AY Subseries.
2.
SI31, SO31, and SCK31 are incorporated only in the
µPD78F0034A 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
µPD78F0034A and 78F0034AY 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.
