3.2Power on/Power off/Reset Function
3.2.1 Power on
MODULE can be powered on by pulling the PWRKEY pin down to ground.
The PWRKEY pin has been pulled up with a diode to 1.8V internally, so it does not need to be pulled up
externally. It is strongly recommended to put a100nF capacitor, an ESD protection diode, close to the
PWRKEY pin as it would strongly enhance the ESD performance of PWRKEY pin. Please refer to the
following figure for the recommended reference circuit.
Figure 9: Reference power on/off circuit
Module could be automatically power on by connecting PWRKEY pin to ground via 0R resistor directly.
The power-on scenarios are illustrated in the following figure.
