EZ-USB™ Serial Bridge Controller
Introducing EZ-USB™ Serial Bridge Controller - full-speed bridge controllers with configurable and fixed-function options
EZ-USB™ Serial Bridge Controller is a family of full-speed bridge controllers offering both configurable and fixed-function options. These bridge controllers are the first in the industry to offer configurable serial channels for UART/I2C/SPI interfaces, with the industry’s lowest power consumption in standby mode (5 uA). With the latest addition of fixed-function controllers, it can be easily configured to work as USB to UART, USB to I2C, or USB to SPI bridges without requiring any firmware development by the user.
The EZ-USB™ Serial Bridge Controller family integrates 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).
