Block Diagram
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 and antenna ports.
• Digital Audio interface for external codec.
• 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
