V
CC
12 10 Input Power supply pin. Connect this pin to the
system power supply.
Power
source
pins
V
SS
9 7 Input Ground pin. Connect this pin to the system
power supply (0V).
AV
CC
3 1 Input Analog power supply pin for the A/D converter.
When the A/D converter is not used, connect
this pin to the system power supply.
V
CL
6 4 Input Internal step-down power supply pin. Connect a
capacitor of around 0.1 µF between this pin
and the Vss pin for stabilization.
OSC1 11 9 Input Clock
pins
OSC2 10 8 Output
These pins connect with crystal or ceramic
resonator for the system clock, or can be used
to input an external clock.
See section 5, Clock Pulse Generators, for a
typical connection.
X1 5 3 Input
X2 4 2 Output
These pins connect with a 32.768 kHz crystal
resonator for the subclock. See section 5,
Clock Pulse Generators, for a typical
connection.
System
control
RES 7 5 Input Reset pin. The pull-up resistor (typ. 150 kΩ) is
incorporated. When driven low, the chip is
reset.
TEST 8 6 Input Test pin. Connect this pin to Vss.
NMI 35 25 Input Non-maskable interrupt request input pin. Be
sure to pull-up by a pull-up resistor.
