Interfaces
2.1 Host interfaces
The module has two high speed host interfaces:
•
•
USB (default): USB 2.0 device interface with LPM support
SDIO: SDIO 2.0 device interface
The interface is selected by the USB/SDIO-n signal. Only one interface can be used in an application.
2.1.1 USB interface
USB is the default interface; USB/SDIO-n signal has an internal pull-up and need not be connected
while using the USB interface. See also Pin definition. The USB device interface is compliant with the
Universal Serial Bus Specification, Revision 2.0, April 27, 2000. A USB host uses the USB cable bus
and the USB 2.0 device interface to communicate with the module.
The USB device interface supports:
•
•
•
•
High/full speed operation (480/12 Mbps)
Suspend/host resume/device resume (remote wake-up)
Built-in DMA engine that reduces interrupt loads on the embedded processor and reduces the
system bus bandwidth requirement for serving the USB device operation
Link Power Management (LPM), corresponding host resume, or device resume (remote wakeup)
to exit from L1 sleep state
The USB voltage levels depend on the USB speed. See also Electrical specifications.
2.1.2 SDIO interface
LILY-W1 supports an SDIO device interface that conforms to the industry-standard SDIO
Full-Speed card specification. The SDIO is activated by pulling down the USB/SDIO-n signal. See also
Pin definition
The module acts as the device on the SDIO bus. The host unit can access registers of the SDIO
interface directly and can also access shared memory in the device through the use of BARs and a
DMA engine.
The SDIO device interface supports:
•
•
•
•
On-chip memory used for CIS
Supports 1-bit and 4-bit SDIO transfer modes at the full clock range of 0 to 50 MHz
Special interrupt register for information exchange
Card to interrupt host
The SDIO 2.0 device interface (1-bit SDIO, 4-bit SDIO transfer modes at full clock range up to 50 MHz)
supports all mandatory SDIO commands.
In 4-bit SDIO mode, data is transferred on all 4 data pins (SDIO_D[3:0]). The interrupt pin is not
available for exclusive use as it is utilized as a data transfer line. This means that if an interrupt
function is required, special timing is required to provide the interrupts. The 4-bit SDIO mode provides
the highest data transfer possible – up to 100 Mbps.
The required pull up for SD interface on SD_CMD, SD_D [3:0] should be provided by the host. The pull
up value is between 10 k to 100k Ω in accordance with SDIO v2.0 specifications. 33 Ω inline resistors
may be needed to help with signal integrity. The SDIO signals levels are selectable and are relative to
the VCC_IO 1.8/3.3 voltage levels defined in Power supply interfaces.
For more information about SDIO design, see also the LILY-W1 series system integration manual [2].

LILY-W1 series - Data sheet
2.2 Antenna interfaces
The LILY-W1 series supports either an internal antenna (LILY-W132 and LILY-W133) or external
antennas connected through an antenna pin (LILY-W131).
2.2.1 Internal antenna
LILY-W132 and LILY-W133 has an internal (embedded) 2.4 GHz PIFA antenna. The internal antenna
is a PIFA antenna specifically designed and optimized for the LILY form factor.
Keep a minimum clearance of 5 mm between the antenna and the casing. Keep a minimum of 10 mm
free space from the metal around the antenna including the area below. If a metal enclosure is
required, use LILY-W131 and an external antenna.
Ideally, LILY-W132 or LILY-W133 are placed so the internal antenna is in the corner of the host PCB
(with the corner closest to pin 11 in the corner). The next best option is to position the antenna side
(short side closest to the antenna) along one side of the host PCB ground plane. It is beneficial to have
a large solid ground plane on the host PCB and have a good grounding on the LILY-W132 module. The
minimum ground plane size is 24 x 30 mm, but a size of more than 50 x 50 mm is recommended.
LILY-W133 has an integrated normal SAW band pass filter, and LILY-W132 module has an integrated
LTE BAW band pass filter for optimal LTE and Wi-Fi coexistence applications.
For more information about the antenna design, see also the LILY-W1 series system integration
manual [2].
⚠
The ANT signal is not available on the solder pins of the LILY-W132 and LILY-W133 modules, and
no antenna diversity functionality is available for these variants.
2.2.2 External RF antenna interface
LILY-W131 has an antenna signal (ANT) pin with a characteristic impedance of 50 Ω for using an
external antenna. The antenna signal supports both Tx and Rx.
The external antenna, for example, can be an SMD antenna (or PCB integrated antenna) on the host
board. An antenna connector for use with an external antenna through a coaxial cable could also be
implemented. A cable antenna might be necessary to use if the module is mounted in a shielded
enclosure like a metal box or cabinet.
An external antenna connector (U.FL. connector) reference design. The LILY-W1 series system
integration manual [2] must be followed to comply with the LILY-W1 FCC/IC modular approvals. See
also Approved antennas.
LILY-W131 also supports an antenna diversity solution with an external antenna switch, as shown in
Figure 2. The switch is controlled by the ANT_SEL and the inverse ANT_SEL-n control signals are
controlled from LILY-W131. For more information about antenna switch design, see also the LILY-W1
series system integration manual [2].

Interfaces
Page 10 of 41
LILY-W1 series - Data sheet
LILY-W131 can be used in coexistence with an LTE modem. An external additional LTE band pass
filter may be required depending on the location of the antennas. See also the LILY-W1 series system
integration manual [2] for a list of suitable LTE filters.
⚠
The FCC/IC modular approvals are not including an additional LTE filter or an antenna switch
design.
2.3 Power supply interfaces
The power for LILY-W1 series modules is supplied through VCC and VCC_IO pins by DC voltage.
☞
The system power supply circuit must be able to support peak power (add 20% as margin over the
typical listed current consumption), as during operation, the current drawn from VCC and VCC_IO
can vary significantly based on the power consumption profile of the Wi-Fi technology.
The separate VCC_IO pin enables integration of the module in either a 1.8 V or 3.3 V application
without any level converters. The module performs calibration when the device is powered up.
2.4 Power mode interfaces
LILY-W1 series modules support external power management control through the Power Down
(PD-n), Host wake up (HOST_WKUP) and the Wake up (WAKE_UP) pins.
2.4.1 Reset
The module is reset to its default operating state under the following conditions:
•
Internal reset: The module is reset, and the internal CPU starts the boot sequence when the
following internal reset events occur:
o Power-on reset (POR): Device receives power supplies rise (triggers internal POR circuit)
o Software/Firmware reset: Host driver issues a soft reset
• External pin assertion (PD-n): The module is reset, and the internal CPU begins the boot sequence
when the PD-n input pin transitions from low to high following the power-up sequence. See also
Power down.
2.4.2 Power down
For applications that do not use Wi-Fi, the device can be put into a low-leakage mode of operation
using the one of the following methods:
•
•
Using PD-n pin: The power-down state provides the lowest leakage mode of operation. Assert
PD-n low to enter power-down. This must be met to enter a power-down state.
All rails powered off: Alternatively, VCC and VCC_IO can be powered off. In this case, the state of
the PD-n pin is irrelevant.
During power-up the PD-n signal should be low or following the VCC signal.
2.4.3 Sleep
The module Power Save Mode (PSM) implementation is achieved through the coordination of the
driver, firmware, and hardware signals HOST_WKUP and WAKE_UP. See also the LILY-W1 series
system integration manual [2].
