Absolute maximum ratings

Absolute maximum rating for digital and analog pins of SIM7000 are listed in the following table:
Table 28: Absolute maximum ratings
Parameter
Voltage on VBAT
Voltage on USB_VBUS
Voltage at digital pins
(RESET,GPIO,I2C,UART,PCM)
Voltage at PWRKEY
ADC
The absolute parameter is tested when VBAT has the power but the PWRKEY has no pulled down.
If it is over the range, the module will be damage. If the power supply on VBAT pin had been shut
down, and the other pin should not have the voltage. Otherwise, it may lead to abnormally boot up
or damage the module.
