Module supply input
VCC supply circuit affects the RF performance and
compliance of the device integrating the module with
applicable required certification schemes.

Ground
GND pins are internally connected each other.
External ground connection affects the RF and thermal
performance of the device.

V_INT
5
O
Generic digital
interfaces supply output
V_INT = 1.8 V (typical) generated by internal DC/DC
regulator when the module is switched on.
Test-Point for diagnostic access is recommended.
See section 1.5.2 for functional description.
See section 2.2.2 for external circuit design-in.
System
PWR_ON
20
I
Power-on input
The PWR_ON input is pulled up to an internal voltage
(dVdd) minus a diode drop. As per the design, this causes
the PWR_ON pin's VIL(max) to vary from 0.35 V up to 0.67 V
based on the diode drop offered.
Active-low module power-on/off input.
Test-Point for diagnostic access is recommended.
See section 1.6.1 for functional description.
See section 2.3.1 for external circuit design-in.
RESET_N

I
External reset input
Active-low module reset input.
Internal pull-up to V_INT.
Test-Point for diagnostic access is recommended.
See section 1.6.3 for functional description.
