NOTE
All ground pins must be connected together in the application.
1.8.3.1
VDDX1, VDDX2, VSSX1, VSSX2 — Power Pins and Ground Pins
VDDX1 and VDDX2 are the 5V power supply output for the I/O drivers. This voltage is generated by the
on chip voltage regulator. Bypass requirements on VDDX1 and VDDX2 pins depend on how heavily the
MCU pins are loaded. All VDDX pins are connected together internally. All VSSX pins are connected
together internally.
1.8.3.2
VDDA, VSSA — Power Supply Pins for ADC
These are the power supply and ground input pins for the analog-to-digital converter and the voltage
regulator.
NOTE
The reference voltages VRH and VRL are internally connected to VDDA
and VSSA.
1.8.3.3
VSS — Core Ground Pin
The voltage supply of nominally 1.8V is generated by the internal voltage regulator. The return current
path is through the VSS pin.
1.8.3.4
LGND — LINPHY Ground Pin
LGND is the ground pin for the LIN physical layer LINPHY.
1.8.3.5
LSGND — Ground Pin for Low-Side Drivers
LSGND is the shared ground pin for the low-side drivers.
1.8.3.6
VSUP — Voltage Supply Pin for Voltage Regulator
VSUP is the 12V/18V shared supply voltage pin for the on chip voltage regulator. This pin is also used as
the high-side driver supply.
