FT-X Series ICs – Full Speed USB Peripheral Bridges

The new FT-X series of Full Speed USB device bridges offer more interface options with lower power, lower pin count and higher levels of integration.

The devices all include an integrated crystal and an internal Multi-Time-Programmable (MTP) Memory for configuring and storing the device descriptors. Taken together these features provide extra system functionality, thus reducing the system bill of material (BOM) and overall printed circuit board (PCB) real estate.In addition, a new Battery Charger detection feature is now included for use, enabling higher charging currents and shorter charging times.
