DVDD0, DVDD1, DVDD2, and AVDD
These are power supply pins. DVDD0, DVDD1, and DVDD2 are connected to the power supply of a digital
circuit and AVDD is connected to a power supply of an analog circuit. Connect these pins near the LSI and
insert bypass capacitors of 10 µF (electrolysis type) and 0.1 µF (ceramic type) between DGND and AGND in
parallel.
DGND0, DGND1, DGND2, and AGND
These are ground pins. DGND0, DGND1, and DGND2 are connected to grounds of digital circuits and AGND
is connected to a ground of an analog circuit. Connect these pins near the LSI.
VREGOUT
This is an output pin of an internal regulator voltage (about 2.5 V).
Connect a capacitor of about 0.1 µF (ceramic type) in parallel to about 10 µF (ceramic or tantalum type) between
this pin and a ground pin.
VBG
This is a reference output pin for an internal regulator.
Connect a laminated ceramic capacitor of about 150 pF between this pin and a ground pin.
TST0 and TST1
These are input pins for testing. At normal use, input “0”.
