Full-speed bridge controllers with configurable and fixed-function options

Empower USB 2.0 with Infineon’s EZ-USB™ Serial Bridge Controllers. They are the first in the industry to offer configurable serial channels (up to 2) for UART/SPI/I2C interfaces, with industry’s lowest power consumption in stand-by mode (5 uA).

The EZ-USB™ Serial Bridge Controllers integrate the industry-leading CAPSENSE™ capacitive-touch sensing technology (for touch sensitive key switches) and USB-IF battery charging specification ver. 1.2 (to detect the source of power on the USB port).

Solution to common design challenges

Engineers face different challenges when implementing USB into their applications:

  • USB implementation is complex and time consuming
  • USB devices must be interoperable with USB hosts and hubs
  • USB firmware development requires deep knowledge of the USB standard
  • USB drivers must work with all popular host operating systems

By using Infineon’s EZ-USB™ Serial Bridge Controller engineers can overcome those design challenges.
