Data Sheet U14042EJ4V0DS
1. PIN CONFIGURATION (TOP VIEW)
64-pin plastic SDIP (19.05 mm (750))
Notes 1.
SDA0 and SCL0 are incorporated only in the
μ
PD780024AY Subseries.
2.
SI31, SO31, and SCK31 are incorporated only in the
μ
PD780024A Subseries.
Cautions 1. Connect the IC (Internally Connected) pin directly to V
SS0
or V
SS1
.
2. Connect the AV
SS
pin to V
SS0
.

PD780021A, 780022A, 780023A, 780024A, 780021AY, 780022AY, 780023AY, and 780024AY
are used in applications where the noise generated inside the microcontroller needs to be reduced, the
implementation of noise reduction measures, such as supplying voltage to V
DD0
and V
DD1
individually
and connecting V
SS0
and V
SS1
to different ground lines, is recommended.
