USB Type-C Controllers are Compatible with Latest Type-C Specifications

Fairchild's FUSB302 family of USB Type-C controllers are the industry's first to be compatible with the latest updates to the USB Type-C standard, including Power Delivery (PD) specification. This enables manufacturers using the FUSB302 to easily support all current and previous versions of the USB Type-C specifications in their products. The USB Implementer Forum (IF) recently released updates to the USB Type-C, USB Type-C Cable and Connector, and USB Power Delivery specifications. The updates resolve known issues and add important new features, including support for new IEC power supplies.

Unlike other USB Type-C controllers, the FUSB302 was designed for use with existing microprocessors via the I2C protocol. This flexibility allows changes to the various USB Type-C specifications to be easily supported via firmware rather than hardware.

The new FUSB302B is the latest addition to the FUSB302 family. It is the smallest USB Type-C controller with PD capability currently available, measuring a mere 1.2 mm x 1.3 mm in a 9-ball WLCSP package. Its small size is complimented by its ultra-low power consumption of 25µA, a critical advantage for battery-powered devices. FUSB302B also supports data role swap, power role swap, hard reset, soft reset, active cables and vendor defined messages (VDM) packet transmission.
