Name

Type

Function

VDDA

Analog Power 2.5V ~ 3.6V

LNA

I/O

RF antenna interface

Chip output impedance=39+j6 Ω. It is suggested to retain the π-type

matching network to match the antenna.

VDD3P3

Ampliﬁer Power 2.5V ~ 3.6V

VDD3P3

Ampliﬁer Power 2.5V ~ 3.6V

VDD_RTC

NC (1.1V)

TOUT

ADC pin. It can be used to test the power-supply voltage of VDD3P3

(Pin3 and Pin4) and the input power voltage of TOUT (Pin 6). However,

these two functions cannot be used simultaneously.

CHIP_PU

Chip Enable

High: On, chip works properly

Low: Off, small current consumed

XPD_DCDC
