Figure 1 shows an overview of the internal architecture of the LE910Cx module.
It includes the following sub-functions:
 Application processor, Modem subsystem and Location processing with their external
interfaces. These three functions are contained in a single SOC.
 RF front end, including antenna diagnosis circuitry
 Analog Audio codec for attaching external speaker amplifier and microphone
 Rich IO interfaces. Depending on which LE910Cx software features are enabled, some of its
interfaces that are exported due to multiplexing may be used internally and thus may not
be usable by the application.
 PMIC with the RTC function inside
