7.2. RF Antenna Interface
7.2.1. 2.4 GHz Radio
The SGW111X series BLE modules each has its own 2.4 GHz antenna solution:
o The SGW1110 modules use a PCB trace antenna integrated into the module’s PCB. This
low-profile antenna solution is useful in space constrained designs.
o The SGW1111 modules provide an onboard antenna connector with a nominal
characteristic impedance of 50Ω.
7.2.2. Near Field Communication (NFC)
The SGW111X series modules includes a Near Field Communication interface capable of
operating as a 13.56 MHz NFC tag, at a bit rate of 106 kbps. As an NFC tag, the data can be read
from or written to the SGW111X modules using an NFC reader.
Two pins are available for connecting to an external NFC antenna: NFC1 (P0.09) and NFC2
(P0.10).
7.3. General Purpose I/O
There are a total 48 available GPIO pins for user application. Each pin can be programmable
individually with the following configurable features:
o Input/output direction
o Output drive strength
o Internal pull-up and pull-down resistors
o Wake-up from high or low-level triggers on all pins
o Trigger interrupt on all pins
o All pins can be individually configured as a serial interface or quadrature demodulator signal
