PCB Design
The decoupling capacitors for pins VCP, VREF, VBUF, and VREG should
be placed as close to the pins as possible, and the equivalent
resistance of the traces should be minimized. The other ends of the
decoupling capacitors for VREF, VBUF, and VREG are connected to the
nearest AVSS _ LN and then to signal ground via a magnetic bead.
The decoupling capacitors for VCC and VIO are also placed close to
the corresponding pins. When VCC is in normal operation, the
overall current will be about 35 mA, which requires a wide PCB
trace to ensure voltage stability. For smooth assembly of the
device, try to avoid routing under the package. Locate components
to avoid areas of stress concentration. It is necessary to avoid
large heat dissipation elements and areas with external mechanical
contact, extrusion and pulling, as well as areas where positioning
screws are prone to warping during overall installation.
