Physical Interfaces 4.1 Power Supply 4.1.1 Linear Regulators FLC-WFM301 contains four linear regulators: A low-voltage regulator to supply the 1.2V core digital supply Three low-voltage regulators for the 1.2V core auxiliary, radio and RF synthesizer analogue supplies 4.1.2 LDO for Digital Supply VREG_IN_DIG is the input voltage to the internal LDO for digital supply and VDD_DIG is the output of the LDO. A low ESR 2.2uF capacitor to ground should be connected to this pin. 4.1.
FLC-WFM301 Datasheet 4.3 RF Interface The module integrates a band-pass filter to the antenna port which is a 50 port. The user can connect a 50 antenna directly to the antenna port (pin 48). 4.4 General Purpose Digital IO There are nine general purpose digital IOs defined in the module. All these GPIOs can be configured by software to realize various functions, such as button controls, LED displays or interrupt signals to host controller, etc. Do not connect them if not use.

FLC-WFM301 Datasheet 4.6.1.2 Host Sleep and Wake-up The normal method for WFM301CL to wake the host up is via the in-band interrupt on SDIO_DATA[1]. This is the dame mechanism that is used to notify the host of received data or interesting events; no explicit sleep signaling is required. An alternative out-of-band mechanism is provided for hosts that cannot utilize the SDIO interrupt as a wake-up signal, e.g. where a separate power-management IC needs to restore power to the host processor.

FLC-WFM301 Datasheet 8. Recommended PCB Layout and Mounting Pattern Placement and PCB layout are critical to optimize the performances of a module without on-board antenna designs. The trace from the antenna port of the module to an external antenna should be 50 and must be as short as possible to avoid any interference into the transceiver of the module. The location of the external antenna and RF-IN port of the module should be kept away from any noise sources and digital traces.
FLC-WFM301 Datasheet Distance between connection and ground area on the top layer should at least be as large as the dielectric thickness. Routing the RF close to digital sections of the system board should be avoided. To reduce signal reflections, sharp angles in the routing of the micro strip line should be avoided. Chamfers or fillets are preferred for rectangular routing; 45-degree routing is preferred over Manhattan style 90-degree routing.
