Description
RF_PORT1
N12
NA
Inout
NA
Secondary antenna port, used for Antenna
diversity. If used, connect to Antenna with
a 50 Ω impedance as per the Reference
Schematics. If unused, leave unconnected
RF_PORT2
N14
NA
Inout
NA
Default Antenna port. Connect to Antenna
with a 50 Ω impedance as per the
Reference Schematics
RESET_N

UULP_VBATT_1
Input
NA
Active-low reset asynchronous reset
signal
POC_IN
H1
UULP_VBATT_1
Input
NA
Power On Control Input
This is an input to the chip. It should be
made high only after supplies are valid to
ensure the IC is in safe state until valid
power supply is available.
POC_OUT
J2
UULP_VBATT_1
Ouput
NA
Power On Control Output
This is internally generated. Initially, it is
low. But it becomes high when the
supplies (VBATT, UULP_VOUTSCDC) are
valid.
