These pins are input pins to AC amplifier. Cut off
DC components of input signals with capacitor.
• ADC1, ADC0
• Analog inputs to 6-bit resolution A/D converter
Positive power supply. Supplies 5 V ±10% when
CPU and peripheral functions operate. When clock
is stopped, data can be retained at 2.2 V. When
VDD rises, internal power-ON reset circuit resets
µPD17010.
Do not apply voltage higher than VDD pin to any pin
other than VDD pins (VDD1 and VDD2 pins). Especially
exercise care when raising both VDD and CE pins
simultaneously as it may cause latch up.
Be sure to connect VDD1 and VDD2 pins to the same
voltage level.
VDD2 pin supplies power to crystal oscillation circuit
(XIN and XOUT pins) and error out circuit (EO0 and
EO1 pins), and VDD1 pin supplies power to the other
circuits.
