FUNCTIONAL DESCRIPTION
FUNCTIONAL PIN DESCRIPTION
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 data sheet.
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 VSSA via
separate traces.
For details, refer to the 68HC908EY16 data sheet.
TEST PIN (FLSVPP)
This pin is for test purposes only. Do not connect in the
application or connect to GND.
PWMIN PIN (PWMIN)
This pin 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 PIN (RXD)
This pin is the output of LIN transceiver. The pin must be
connected to the microcontroller’s Enhanced Serial
Communications Interface (ESCI) module (RXD pin).
RESET PIN (RST_A)
RST_A
is the reset output pin of the analog die and must
be connected to the RST pin of the MCU.
Important
To ensure proper operation, do not add any
external pull-up resistor.
INTERRUPT PIN (IRQ_A)
IRQ_A
is the interrupt output pin of the analog die
indicating errors or wake-up events. This pin must be
connected to the IRQ pin of the MCU.
WINDOW WATCHDOG CONFIGURATION PIN
(WDCONF)
This pin is the configuration pin for the internal watchdog.
A resistor is connected to this pin. The resistor value defines
the watchdog period. If the pin 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 pin
to GND.
POWER SUPPLY PINS (VSUP1 AND VSUP2)
This VSUP1 power supply pin supplies the voltage
regulator, the internal logic, and LIN transceiver.
This VSUP2 power supply pin is the positive supply for the
high side switches.
POWER GROUND PIN (GND)
This pin is the device ground connection.
HIGH SIDE OUTPUT PINS (HS1 AND HS2)
These pins are high side switch outputs to drive loads such
as relays or lamps. Each switch is protected with over-
temperature and current limit (over-current). The output has
an internal clamp circuitry for inductive load. The HS1 and
HS2 outputs are controlled by the SPI and have a direct
enabled input (PWMIN) for PWM capability.
HIGH SIDE OUTPUT PIN (HS3)
This high side switch can be used to drive small lamps,
Hall-effect sensors, or switch pull-up resistors. The switch is
protected with over-temperature and current limit (over-
current). The output is controlled only by the SPI.
LIN BUS PIN (LIN)
The LIN pin 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 PINS (L1 AND L2)
These pins 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 pins can
be read through the SPI.
Important
If unused, these pins should be connected to
VSUP or GND to avoid parasitic transitions. In Low Power
Mode, this could lead to random wake-up events.
CURRENT SENSE OPERATIONAL AMPLIFIER
PINS (E+, E-, OUT, VCC)
These are the pins of the single supply current sense
operational amplifier.
The E+ and E- input pins are the non-inverting and
inverting inputs of the current sense operational
amplifier, respectively.
The OUT pin is the output pin of the current sense
operational amplifier.
The VCC pin is the +5.0 V single supply connection.
