RAP ASIC

RAP ASIC is a 2G Radio Application Processor.
In general RAP consists of three separate parts:
• Processor subsystem (PSS) that includes the main processor and related functions
• MCU peripherals that are mainly controlled by MCU
• DSP peripherals that are mainly controlled by DSP
RAP core voltage (1.4 V) is generated from the EM ASIC (N2300) VCORE and I/O voltage (1.8 V) is from the EM
ASIC (N2200) VIO. The core voltage in sleep mode is 1.05 V.

EM ASIC N2200

EM ASIC N2200 includes the following functional blocks:
• Start up logic and reset control
• Charger detection
