Connectivity
Wireless connectivity
ST’s portfolio offers a variety of wireless ICs and modules to address the needs of designers for their
applications. Low-power wireless connectivity represents the key technology for connecting smart objects
to the internet and the cloud. As a matter of fact, wireless connectivity is not dominated by one single
technology. Depending on application needs or technology constraints, different hardware and software
integration requirements must be considered.
SPWF01S series of Wi-Fi Modules
The SPWF01S series of Wi-Fi modules offers a fast, flexible and affordable Plug&Play solution
for integration of 802.11 b/g/n and TCP/IP technologies in IoT devices. The modules integrate
a complete TCP/IP stack and a user-friendly application layer that ensures a simple and
effective way to use the modules via AT commands. The modules are configured around a
single-chip 802.11 transceiver with integrated PA and an STM32 32-bit microcontroller with
extensive GPIO support. The modules also incorporate timing clocks and voltage regulators.
Multiple antenna options are available.

ESD protection
ESD protection devices
Wearable devices are by nature vulnerable to ESD. Indeed, they are small integrated devices using ESD-sensitive ICs with thin lithography
technologies and in close contact with electrostatic charges that a human can develop in low relative humidity. The risk of ESD damage is then
very high.
Benefits of ST's current ESD protection devices:
• High efficiency of protection with low clamping voltages
• Transparency to high-speed signals with ultra-wide bandwidth up to 13 GHz
• Flexibility and Integration with single- or multi-line products from 01005 package size
• High robustness against surges with capability up to 30 kV
• High Ipp versions to combine EOS and ESD in smallest packages

EMI filtering
EMI and common-mode filters
Wearable devices are sensitive to electro-magnetic interference. They are small integrated devices with a high density of components mounted
on PCB. The risk of antenna desense and EMI coupling must be mitigated.
ST offers a wide range of EMI and common-mode filters (ECMF™) with the following benefits:
• Drastically reduce radiated noise and antenna de-sense with unique extra large rejection band or extra deep rejection at selected frequencies
• High integration: 1mm2 for 2 differential lines for ECMF™
• High quality of protection with low clamping voltages

Wearable Solution Evaluation Board
ST is offering also a reference platform for easy development of wearable applications, thanks
to its design: compact solution, ultra-low power hardware and firmware features, a complete
set of firmware example and turnkey software on host device (i.e. an Smartphone or Tablet).
The STEVAL-WESU1* is an Evaluation Board designed to provide a cost effective solution for
precise motion sensing. The system is featuring a low power ARM Cortex-M3 microcontroller
unit (STM32L151), an iNEMO inertial module (LSM6DS3), a high performance magnetometer
(LIS3MDL), a barometric pressure sensor (LPS25HB), a Bluetooth® low energy wireless network
processor (BlueNRG-MS) and power management circuitry that allows fast charging and
precise energy estimation (STNS01 and STC3115). The connectivity granted by the best in
class BlueNRG and supported by the integrated balun (BALF-NRG-01D3) permit to maximize
the RF performances with low area occupancy and design effort and pass the RF Test for FCC
and IC certification.
An Android and iOS APP, available on Google Play and Apple Store, can be used for displaying
information sent by the STEVAL-WESU1* through BLE connectivity as well as for setting
operative modes.
