The EMMY-W1 series provides a complete short range transceiver solution that can easily be integrated into
automotive and industrial applications. The modules are designed for both simultaneous and independent
operation of the following technologies:
IEEE 802.11a/b/g/n/ac data rates for Wi-Fi
Dual-mode Bluetooth v4.2
NFC
The EMMY-W1 series is a surface-mount device (SMD) component and can be used as a Wi-Fi micro-access point
supporting up to 10 clients. A coexistence feature at the chip level improves parallel use of Bluetooth and Wi-Fi
communication. For highest throughput and performance, a module variant with separate Wi-Fi and Bluetooth
antenna pins is also available.
The modules include an integrated MAC/baseband processor and RF front-end components and can connect to
a host processor through SDIO 3.0 and high-speed UART interfaces. The EMMY-W1 series are offered in
automotive and professional grades (see Ordering codes and Block diagrams). The automotive grade variant
includes an automotive-qualified (AEC-Q100) chipset. A host driver for Linux 3.x is available free of charge. The
modules are radio type approved for Europe (ETSI R&TTE), US (FCC CFR 47 part 15 unlicensed modular
transmitter approval), Canada (IC RSS), Korea (KCC)1, Japan (MIC)1 and Australia / New Zealand (ACMA)2.
Approvals for other countries may be possible upon inquiry.

In EMMY-W161, the band pass filter (2.4 GHz BPF) is a BAW filter that enables co-existence with
LTE. For the EMMY-W165 variant, the band pass filter provides no co-existence protection against
a co-located LTE transmitter.
In EMMY-W163, the bandpass filters (2.4 GHz BPF) are ceramic bandpass filters. An LTE co-existence variant
is not available in the dual-antenna configuration.
1.5 Product description
The EMMY-W161 is recommended for applications that have co-located Wi-Fi, Bluetooth and LTE antennas
and require co-existence of these wireless technologies. This module provides a dedicated BAW bandpass
filter instead of the ceramic bandpass filter. This filter rejects the adjacent LTE bands B40, B7, B41 and B38.
The integrated BAW filter is available only for the single-antenna configuration (EMMY-W161). The module
pinout, operating conditions, and electrical characteristics are identical for all product variants. Differences
in the RF parameters are explained in the Radio specifications section.

1.7 Additional reserved MAC addresses
The EMMY-W1 module series has four unique consecutive MAC addresses reserved for each module, from
which the first two addresses are already stored in the configuration during production. The first address is used
for the Bluetooth communication while the second address is configured for Wi-Fi communication. The Data
Matrix Code on the label includes the Bluetooth MAC address (see section 9). The remaining two MAC
addresses are not used in the manufacturing configuration, but are reserved for usage with the module.

2 Interfaces
2.1 Operation mode configuration
EMMY-W1 series module uses the GPIO_3 and GPIO_2 pins as host interface configuration input to set the
desired operation mode following a reset. The definitions of these pins are changed to their usual functions after
reset. When you need to configure the pins for a certain module operation mode, you need to provide a 100 kΩ
pull down resistor to the ground. No external circuitry is required to set a configuration pin to high logical level.
External reset is not needed for proper operation due to internal power-up reset logic though it can be used by
the host controller through the PDn pin (active low) in case of an abnormal module behavior.
After reset, GPIO_3 and GPIO_2 pins can be used as open drain outputs (depending on firmware/driver version)
for Bluetooth and Wi-Fi activity LED indicators, but simultaneous usage of an LED connected to 3.3 V power line
and a pull-down resistor is not allowed (LED acts as a strong pull-up circuitry). Do not connect LED if you need
the pull-down resistors.
Depending on the firmware or driver used, you can use either one or both host interface operation modes:
Table 3: Module configuration
2.2 SDIO interface
EMMY-W1 series modules support an SDIO device interface that conforms to the industry standard SDIO 3.0
Full-Speed specification (4-bit SDIO up to 208 MHz) and allows a host controller using the SDIO bus protocol to
access the Wi-Fi and Bluetooth functions. The interface supports 4-bit SDIO transfer mode at the full clock range
of 0 to 208 MHz.
