TYPICAL APPLICATIONS
LIN Pin
For DPI (Direct Power Injection) and ESD (Electrostatic
Discharge), it is recommended to place a high quality ceramic
decoupling capacitor near the LIN pin. An additional varistor
will further increase the immunity against ESD. A ferrite in the
LIN line will suppress some of the noise induced.
Voltage Regulator Output Pins (VDD and VSS)
Use a high quality ceramic decoupling capacitor to
stabilize the regulated voltage.
MCU Digital Supply Pins (EVDD and EVSS)
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. It is recommended that a high quality
ceramic decoupling capacitor be placed between these pins.
MCU Analog Supply Pins (VREFH/VDDA and VREFL/
VSSA)
To avoid noise on the analog supply pins, its important to
take special care on the layout. The MCU digital and analog
supplies should be tied to the same potential via separate
traces and connected to the voltage regulator output.
Figure 34 and Figure 35 show the recommendations on
schematics and layout level, and Table 23 indicates
recommended external components and layout
considerations.
