Functional Description
Functional Terminal Description
Fast signal transitions on MCU terminals 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.
ADC SUPPLY TERMINALS (VDDA AND VSSA)
VDDA and VSSA are the power supply terminals for the
analog-to-digital converter (ADC). It is recommended that a
high-quality ceramic decoupling capacitor be placed between
these terminals.
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 terminal for the ADC and should be tied
to the same potential as EVSS via separate traces.
For details refer to the 68HC908EY16 datasheet.
ADC REFERENCE TERMINALS (VREFL AND
VREFH)
VREFL and VREFH are the reference voltage terminals for
the ADC. It is recommended that a high-quality ceramic
decoupling capacitor be placed between these terminals.
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 VSSA via
separate traces.
For details refer to the 68HC908EY16 datasheet.
TEST TERMINAL (FLSVPP)
This terminal is for test purposes only. Do not connect in
the application.
PWMIN TERMINAL
This terminal is the direct PWM input for high-side
outputs 1 and 2 (HS1 and HS2). If no PWM control is
required, PWMIN must be connected to VDD to enable the
HS1 and HS2 outputs.
LIN TRANSCEIVER OUTPUT TERMINAL (RXD)
This terminal is the output of LIN transceiver. The terminal
must be connected to the microcontroller’s Enhanced Serial
Communications Interface (ESCI) module (RXD terminal).
RESET TERMINAL (RST_A)
RST_A
is the reset output terminal of the analog die and
must be connected to the RST terminal of the MCU.
Important
To ensure proper operation, do not add any
external pullup resistor.
INTERRUPT TERMINAL (IRQ_A)
IRQ_A
is the interrupt output terminal of the analog die
indicating errors or wake-up events. This terminal must be
connected to the IRQ terminal of the MCU.
WINDOW WATCHDOG CONFIGURATION
TERMINAL (WDCONF)
This terminal is the configuration terminal for the internal
watchdog. A resistor is connected to this terminal. The
resistor value defines the watchdog period. If the terminal is
open, the watchdog period is fixed to its default value.
The watchdog can be disabled (e.g., for flash
programming or software debugging) by connecting this
terminal to GND.
POWER SUPPLY TERMINALS (VSUP1 AND
VSUP2)
This VSUP1 power supply terminal supplies the voltage
regulator, the internal logic, and LIN transceiver.
This VSUP2 power supply terminal is the positive supply
for the high-side switches.
POWER GROUND TERMINAL (GND)
This terminal is the device ground connection.
HIGH-SIDE OUTPUT TERMINALS (HS1 AND HS2)
These terminals are high-side switch outputs to drive loads
such as relays or lamps. Each switch is protected with
overtemperature and current limit (overcurrent). The output
has an internal clamp circuitry for inductive load. The HS1
and HS2 outputs are controlled by SPI and have a direct
enabled input (PWMIN) for PWM capability.
HIGH-SIDE OUTPUT TERMINAL (HS3)
This high-side switch can be used to drive small lamps,
Hall-effect sensors, or switch pullup resistors. The switch is
protected with overtemperature and current limit
(overcurrent). The output is controlled only by SPI.
LIN BUS TERMINAL (LIN)
The LIN terminal represents the single-wire bus
transmitter and receiver. It is suited for automotive bus
systems and is based on the LIN bus specification.
WAKE-UP TERMINALS (L1 AND L2)
These terminals are high-voltage capable inputs used to
sense external switches and to wake up the device from
Sleep or Stop mode. During Normal mode the state of these
terminals can be read through SPI.
