EZ-USB™ Serial Bridge Controllers

Full-speed bridge controllers with configurable and fixed functions

Infineon's EZ-USB™ Serial Bridge Controllers provide connectivity between USB and UART, SPI and I2C serial interfaces, while offering a very low power consumption in stand-by mode (5 uA).

Fixed-function Controllers

The fixed-function controllers can be easily used to work as USB to UART, USB to I²C, or USB to SPI bridges without requiring any firmware development.

Configurable controllers

You can tune the configurable controllers to your needs with the included configuration utility with dedicated software development kit. On top you will benefit of Infineon’s premium technical support throughout the development phase.

CAPSENSE™ capacitive-touch sensing technology

The portfolio encompasses the industry-leading CAPSENSE™ capacitive-touch sensing technology (for touch-sensitive key switches) and battery charger detection compliant with USB-IF Battery Charging specification ver. 1.2 to detect the source of power on the USB port.
