Name and Function
Power supply pins
These pins should be connected to the
system power supply.
Power supply pin for port H, port J, and
the motor control PWM timer output
and part of port F (PF2 and PF4 to PF6)
Power supply pin for LCD controller/
driver
There is an on-chip power supply
division resistor, so this pin is normally
left open. Power supply conditions:
LPVcc ≥ V1 ≥ V2 ≥ V3 ≥ Vss
Ground pins
These pins should be connected to the
system power supply (0 V).
Power supply pin for port H, port J, and
the motor control PWM timer output
These pins should be connected to the
system power supply (0 V).
Pin for connecting the on-chip step-
down power supply to a capacitor for
voltage stabilization. Connect to Vss via
a 0.1 µF capacitor (which should be
located near the pin). Do not connect
this pin to an external power supply.
Power supply pin for ports A, B, C, D, E,
