The connectivity domain includes all the connectivity options offered in smartphones.

The mobile market predominately uses integrated system-on-chip (SoC) solutions combining at

least Wi-Fi, Bluetooth®, and GPS. ST is more focused on the other connectivity options that can

deliver competitive advantages to mobile makers, such as NFC. ST can offer a wide range of

products enabling NFC data exchange or advanced mobile payment solutions, based on embedded

secure elements.

ST provides a full range of NFC and eSE / eSIM products and solutions to address secure mobile

transaction applications from the state-of-the art ST21NFC NFC controller to the ST54 integrating

the widely deployed ST33 secure element. ST54 now allows a new level of integration by merging

NFC, eSE, and eSIM in the single-die ST54J solution in a compact WLCSP package.

Another connectivity solution offered by ST is the ST60 RF transceiver for the 60 GHz band. It

provides a very power-efficient wireless link with a high data rate, eliminating the need for physical

cables and connectors for short range (a few centimeters) point-to-point communications.
