2 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
Only one interface should be used in an application and the interface is selected by the USB/SDIO-n signal.
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 as mentioned in Pin definition section. 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. Main features of the USB device interface include:
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
Supports 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 Electrical specifications section for additional information.
2.1.2 SDIO interface
SDIO is activated by pulling down the USB/SDIO-n signal as mentioned in the Pin definition section. The module
supports an SDIO device interface that conforms to the industry standard SDIO Full-Speed card specification.
The module acts as the device on the SDIO bus. The host unit can access registers of the SDIO interface directly
and can access shared memory in the device through the use of BARs and a DMA engine. Main features of the
SDIO device interface include:
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
Allows card to interrupt host
SDIO 2.0 device interface (1-bit SDIO, 4-bit SDIO transfer modes at full clock range up to 50 MHz). All
mandatory SDIO commands are supported.
In 4-bit SDIO mode, data is transferred on all 4 data pins (SDIO_D[3:0]), and the interrupt pin is not available for
exclusive use as it is utilized as a data transfer line. Thus, if the interrupt function is required, a special timing is
required to provide 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 according to the SDIO v3.0 specifications. 33 Ω inline resistors may be needed to
help with signal integrity. The SDIO signals levels are selectable according to the VCC_IO 1.8/3.3 voltage levels as
mentioned in the Power supply interfaces section.
See LILY-W1 series System Integration Manual [2] for more information about SDIO design.

LILY-W1 series - Data Sheet
2.2 Antenna interfaces
The LILY-W1 series supports either an internal antenna (LILY-W132) or external antennas connected through an
antenna pin (LILY-W131).
2.2.1 Internal antenna
The LILY-W132 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 10 mm free space
from metal around the antenna including the area below. If a metal enclosure is required, use LILY-W131 and an
external antenna.
It is recommended to place the LILY-W132 module so that the internal antenna is in the corner of the host PCB
(the corner closest to Pin 11 should be in the corner). The antenna side (short side closest to the antenna),
positioned along one side of the host PCB ground plane is the second best option. It is beneficial to have a large
solid ground plane on the host PCB and have a good grounding on the LILY-W132 module. Minimum ground
plane size is 24x30 mm but recommended is more than 50x50 mm.
The LILY-W132 module has an integrated LTE BAW band pass filter for optimal LTE and Wi-Fi coexistence
applications.
The ANT signal is not available on the solder pins of the LILY-W132 module and no antenna diversity
functionality is available.
2.2.2 External RF antenna interface
The LILY-W131 module 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 using an external antenna via a coaxial cable could also be implemented. A cable antenna
might be necessary to use if the module is mounted in a shielded enclosure such as a metal box or cabinet.
An external antenna connector (U.FL. connector) reference design (see LILY-W131 Antenna Connector -
Reference Design [5]) are available and must be followed to comply with the LILY-W1 FCC/IC modular approvals.
Also see and the list of approved antennas (section 7.2).
The LILY-W131 module also supports an antenna diversity solution with an external antenna switch (see Figure
2). The switch is controlled by the ANT_SEL and the inverse ANT_SEL-n control signals are controlled from
LILY-W131. See LILY-W1 series System Integration Manual [2] for more information about antenna switch
design.
Figure 2: LILY-W131 antenna diversity solution with an external antenna switch controlled by LILY-W131
The LILY-W131 can be used in coexistence with a LTE modem. An external additional LTE band pass filter may be
required depending on the location of the antennas. Refer to 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.

LILY-W1 series - Data Sheet
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 listed type
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
The 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) signals.
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 Power down
section for more information.
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 LILY-W1 series System Integration Manual [2]
for more information.
