DIGITAL SECTION
ME310G1 has four main operation states:
• OFF state: Vbatt is applied and only RTC is running. The Baseband is switched OFF
and the only possible change is the ON state.
• ON state: the baseband is fully switched on and ME310G1 is ready to accept AT
commands. ME310G1 can be idle or connected.
• Sleep mode state: the main baseband processor is intermittently switched ON and
AT commands can be processed with some latency. ME310G1 is idle with low
current consumption.
• Deep sleep mode state: PSM defined in 3GPP Release 12. Baseband is switched
OFF most of the time.
