UART_RX
UART receive input. Compatible with +3.3V and +5V
logic.
UART_TX
UART transmit output. Open drain – requires a pull-up
to VDD or +5V (4 mA max). Pull-up value depends on
UART baud rate and the trace length (higher resistor
values can be used with lower baud rates and shorter
traces); typical value is 4.7 k.
PWR_CTRL
External power control output. Used to switch external
circuitry into low-power (sleep) state. Polarity can be
configured in firmware; default configuration is active
high (logic low = sleep mode). Open drain – requires a
pull-up to VDD or +5V (12 mA max); be mindful of the
fact that the pull-up will draw current in low-power
state. Pull up to VDD via 100 kresistor if unused.
VCAP
CPU logic filter capacitor connection. Must be
connected to a low-ESR (< 5) minimum 4.7 μF
capacitor; typical value is 10 μF.
O¯B¯¯D¯_¯T¯X¯_¯L¯E¯D / ¯R¯S¯T¯_¯N¯V¯M¯
Active low OBD transmit activity LED output (12 mA
max) and active low input to reset NVM to factory
defaults. Open drain – requires a pull-up to VDD or
+5V (12 mA max) if not pulled up via an LED
connection. Pull up to VDD if unused.
O¯B¯D¯¯_¯R¯X¯_¯L¯E¯D / I¯N¯T
Active low OBD receive activity LED or interrupt
output (12 mA max). Open drain by default (requires a
pull-up to VDD or +5V when configured as interrupt);
can be configured as a digital output. If unused, pull
STN1110
up to VDD or configure as digital output and leave
unconnected.
U¯A¯R¯¯T¯_¯T¯X¯_¯L¯E¯D
Active low UART transmit activity LED output (4 mA
max). Voltage on the anode of the LED must not
exceed VDD + 0.3V. Leave unconnected if unused.
U¯A¯R¯¯T¯_¯R¯X¯_¯L¯E¯D
Active low UART transmit activity LED output (4 mA
max). Voltage on the anode of the LED must not
exceed VDD + 0.3V. Leave unconnected if unused.
¯IS¯O¯_¯K¯_¯T¯X¯
Active low ISO 9141/ISO 14230 K-line output. When
the pin is logic high, K-line should be low. Leave
unconnected if unused.
¯IS¯O¯_¯L¯_¯T¯X¯
Active low ISO 9141/ISO 14230 L-line output. When
the pin is logic high, L-line should be low. Leave
unconnected if unused.
AVSS
Analog ground reference. Must be connected to
analog “clean” ground (between VSS – 0.3V and VSS
+ 0.3V) or VSS.
AVDD
Analog positive supply. Must be connected to VDD or
an external voltage reference (between VDD - 0.3V or
3.0V, whichever is greater and VDD + 0.3V or 3.6V,
whichever is lesser). AVDD may be decoupled from
digital supply by connecting it to VDD via a 10
resistor.
