duration current demands on the power supply. To prevent
noise problems, take special care to provide power supply
bypassing at the MCU.

EXPOSED PAD TERMINAL
package 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.
Fast signal transitions on MCU terminals place high, short-
