  • Page 33: System States

    The system states of the GS2200M system are as follows: Power OFF: No power source connected to the system. Standby: In the standby state, only the RTC portion of the GS2200M is powered from the VRTC pin. The other power supplies are turned off by the DC_DC_CNTL pin being low.
  • Page 34 GS2200M Architecture GS2200M Low Power WiFi Module Data Sheet Wireless LAN and System Control Subsystem In standby state, the 32.768KHz oscillator keeps running and only the RTC RAM retains the state (how many banks retain their state is SW configurable). SRAM, CPUs and I/Os are all in OFF state, as there is no VREG and no VDDIO being supplied to the GS2200M device.
  • Page 35 The following are not system states, but are related design notes: Power Control: The GS2200M was designed with the intent that power to the non-RTC portions of the chip be controlled from the DC_DC_CNTL signal. In applications where it is preferred that an external host control the power, this is OK if ALL power, including VRTC power, is turned on and off by the external host.
