1. 1) For every VBAT transition/re-insertion from 0V, the minimum power supply voltage should be more
than 2.7V. Meanwhile, in order to guarantee stability and RF performance, the minimum power supply
voltage should be more than 2.8V. After the module starts up normally, the minimum safety voltage is
2.6V.
2. 2) means theoperationis performed with AT+CFUN=0 and AT+QSCLK=1 (DTR pin at high level).
3. 3) Within operation temperature range, the module is 3GPP compliant.
4. 4) Within extended temperature range, the module remains the ability to establish and maintain a
voice, SMS, data transmission, emergency call, etc. There is no unrecoverable malfunction. There
are also no effects on radio spectrum and no harm to radio network. Only one or more parameters like
Pout might reduce in their value and exceed the specified tolerances. When the temperature returns to
normal operation temperature levels, the module will meet 3GPP specifications again.

1. 1) PWRKEY is internally pulled up to an internal voltage in the Qualcomm chipset, and its output
voltage is the internal voltage minus a diode drop in the chipset. For BG95, the expected output
voltage of PWRKEY is 1.5V, and PWRKEY should never be pulled down to GND permanently. For
BG96, the expected output voltage of PWRKEY is 0.8V.
2. 2) BG95 can be reset by driving RESET_N low for 2s to 3.8s. BG96 can be reset by driving RESET_N
low for 150ms to 460ms.
3. 3) BG95 supports ADC0 and ADC1. The two interfaces are internally connected, therefore they
cannot be used simultaneously. If the two ADC interfaces are intended to be used at the same time,
please add an external analog switch.
4. 4) GNSS_TXD of BG95 is a BOOT_CONFIG pin, and it cannot be pulled up before startup.
5. The black colored pin names are defined for BG95. The purple colored pin names are defined for
BG96.
6. The orange color indicates the pins with different functions between BG95 and BG96.
