FUNCTIONAL DESCRIPTION
FUNCTIONAL PIN DESCRIPTION
ADC REFERENCE PINS
(VREFL AND VREFH)
VREFL and VREFH are the reference voltage pins for the
ADC. It is recommended that a high-quality ceramic
decoupling capacitor be placed between these pins.
Important VREFH is the high reference supply for the
ADC and should be tied to the same potential as VDDA via
separate traces. VREFL is the low reference supply for the
ADC and should be tied to the same potential as VSS via
separate traces.
For details refer to the 68HC908EY16 datasheet.
ADC SUPPLY PINS (VDDA AND VSSA)
VDDA and VSSA are the power supply pins for the analog-
to-digital converter (ADC). It is recommended that a high-
quality ceramic decoupling capacitor be placed between
these pins.
Important VDDA is the supply for the ADC and should be
tied to the same potential as EVDD via separate traces.
VSSA is the ground pin for the ADC and should be tied to the
same potential as EVSS via separate traces.
For details refer to the 68HC908EY16 datasheet.
MCU POWER SUPPLY PINS
(EVDD AND EVSS)
EVDD and EVSS are the power supply and ground pins.
The MCU operates from a single power supply.
Fast signal transitions on MCU pins place high, short-
duration current demands on the power supply. To prevent
noise problems, take special care to provide power supply
bypassing at the MCU.
For details refer to the 68HC908EY16 datasheet.
TEST PIN (FLSVPP)
This pin is for test purposes only. This pin should be either
left open (not connected) or connected to GND.
EXPOSED PAD PIN
The exposed pad pin on the bottom side of the 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.
