3.2 Interfaces
Reference circuit design shows the typical hardware connections for the module. Interfacing to the module
requires connecting to the signals provided on the GL5712-UX mPCIe connector as listed in pin description.
Specific interface connections are discussed in
this chapter.
3.2.1 Interface to host MCU
 SPI interface
A SPI interface is provided on the PCIe_SCK, PCIe_MISO, PCIe_MOSI, PCIe_CSN pins of the system connector. The
SPI interface gives access to the configuration register of SX1301 via a synchronous full-duplex protocol. Only the
slave side is implemented.
 USB interface
GL5712-UX series modules can support high speed USB to SPI by FT232H, it include a high-speed USB 2.0
compliant interface with maximum 480 Mb/s data rate, representing the interface for any communication with
an external host application processor. The module itself acts as a USB device and can be connected to any USB
host equipped with compatible drivers. For more information please refer to the data sheet of FT232H.
3.2.2 Power pins
GL5712-UX series modules must be supplied through the 3.3Vaux pins by a DC power supply. The voltage must
be stable, because during this operation the current drawn from 3.3Vaux can vary significantly, based on the
power consumption profile of the SX1301 chip(see SX1301 DS).
