3.2.1 Power Supply
MC610 series modules need to provide power supply through VBAT pins. The recommended power
supply design is shown in the following figure:
Figure 3-2 Recommended power supply design
VBAT power supply needs star route, and the filter capacitor design of power supply is shown in
the following table:

Description
220uFx2,
10uF,22uF
Stabilized capacitance
Low ESR capacitance is required to reduce
the power fluctuation of the module during
operation.
LDO or DCDC power supply requirements
are not less than 440 uF capacitance.
Battery power supply can be reduced to
