2021 –
STMicroelectronics (NYSE: STM), a global semiconductor
leader serving customers across the spectrum of electronics
applications, is protecting wireless charging of small devices and
mobiles with a convenient solution for authenticating certified Qi
chargers.
Wireless charging, enabled on an increasing variety of
smartphones and wearables, is creating opportunities for
innovations that offer extra value for users. These include
furniture with built-in charging pads, cars that position the
charging pad to keep mobiles safely out of reach while driving, and
easy charging in hospitality locations such as cafes and
restaurants. Chargers must be properly designed to protect
consumers’ products, particularly in high-power, fast-charging
modes. The Qi logo is awarded after testing and certifying in
accordance with the WPC-Qi specifications.
“ST is helping wireless charging thrive by providing a secure
way to authenticate genuine Qi-certified chargers before increasing
the charge at any power level over five Watts,” said Laurent
Degauque, Marketing Director, Secure Microcontroller Division,
STMicroelectronics. “Our solutions compliant with WPC-Qi
specification V1.3 are based on ST secure elements certified Common
Criteria EAL5+ and AEC-Q100 for automotive.”
STSAFE secure elements are loaded with official Qi Certificates
and provide authentication that leverages state-of-the-art
cryptography. The solutions clearly identify the charger and
strictly attest to its authenticity as a Qi-certified product.
As an official Manufacturer Certification Authority Service
Provider, ST has the authority to compute and to sign the official
Qi Charger certificate that contains both the charger Qi-ID and
maker reference. The STSAFE-A110, and STSAFE-V110 for automotive
applications, are loaded at a secure ST factory, creating a
ready-to-use solution that relieves the charger makers from the
burden of loading the sensitive data securely.
The STSAFE is trusted in millions of consumables, connected
devices and secure automotive peripherals worldwide to authenticate
devices to protect branded products, and connected assets.
For consumer markets, STSAFE-A110 is available in 4mm x 5mm SO8N
or 2mm x 3mm UFDFPN8 packages. For the automotive market,
STSAFE-V110 is available in TSSOP20 package.

Information
The STSAFE IC family provides common functions and services to
ensure end-to-end security optimized for consumables, connected
devices and automotive peripherals. It relies on state-of-the-art
security audited by independent security authorities and it is
certified Common Criteria EAL5+ AVA_VAN 5.
STSAFE-A110 and STSAFE-V110 consist of a secure operating system
executed on a secure microcontroller. They offer authentication
based on ECDSA asymmetric cryptography and X509 certificates
containing a unique serial number.
For Qi authentication, they are preloaded with the appropriate
cryptographic key and the official Qi Certificate corresponding to
the customer’s Qi charger.
The STSAFE-V110 is certified according to automotive standard
AEC-Q100 grade 2.
Users can also take advantage of a comprehensive STSAFE-A110
ecosystem to support product development and ease integration of
the STSAFE-A110 with the application host system, including ST’s
STM32* microcontroller family, and devices such as ST’s STWBC2
digital controller for wireless battery charger transmitters.
To kickstart development, the X-NUCLEO-SAFEA1A expansion board
for STM32 Nucleo boards contains an STSAFE-A110 IC ready to use
with the X-CUBE-SAFEA1 software package and X-CUBE-SBSFU secure
boot and software update expansion package.
