MCU POWER SUPPLY PINS
(EVDD AND EVSS)
The MCU operates from a single power supply.
duration current demands on the power supply. To prevent
noise problems, take special care to provide power supply
bypassing at the MCU.
TEST PIN (FLSVPP)
left open (not connected) or connected to GND.
EXPOSED PAD PIN
conducts heat from the chip to the PCB board. For thermal
performance the pad must be soldered to the PCB board. It
is recommended that the pad be connected to the ground
potential.
EVDD and EVSS are the power supply and ground pins.
Fast signal transitions on MCU pins place high, short-
