FUSB302 was designed for use with existing microprocessors via the I²C protocol.
Claiming as the first to be compatible with the latest updates to the USB Type-C standard including power delivery (PD) specification, Fairchild's FUSB302 family of USB Type-C controllers enable manufacturers 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.
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.
“Our FUSB302 line of USB Type-C controllers addresses manufacturers’ concerns over updates to the specifications, so they can easily add the next generation of USB functionality to their smartphones, tablets, PCs and other mobile devices,” said Myron Miske, Interface and Protection Product Line Director at Fairchild. “...[making use of] the FUSB302’s combination of small size, low power consumption and ‘investment protection’ advantages.”
The new FUSB302B is the smallest USB Type-C controller with PD capability currently available, measuring 1.2mm x 1.3mm in a 9-ball WLCSP package. Its small size is complemented by its ultra-low power consumption of 25µA. FUSB302B also supports data role swap, power role swap, hard reset, soft reset, active cables and vendor defined messages (VDM) packet transmission.
