1. PIN CONFIGURATION (TOP VIEW)
• 64-pin plastic SDIP (19.05 mm (750))
Remark When the µ PD78F0034A and 78F0034AY are used in application fields that require reduction of the
µ PD78F0034ACW, 78F0034AYCW
Notes 1.
Cautions 1. Connect the V
2.
noise generated from inside the microcontroller, the implementation of noise reduction measures, such
as supplying voltage to V
is recommended.
2. Connect the AV
SDA0 and SCL0 are incorporated only in the µ PD78F0034AY Subseries.
SI31, SO31, and SCK31 are incorporated only in the µ PD78F0034A Subseries.
