Low power, USB Type-C charger & device reference designs from Lattice

February 26, 2015 // By Graham Prophet
Lattice Semiconductor has used its programmable-device platform to create three low power, online solutions for USB Type-C that are intended to reduce development time/risk, and expedite introduction of USB Type-C implementation in consumer and industrial devices

The three freely-downloadable reference designs that enable designers working in consumer, industrial and other sectors to quickly implement the cable detect and power delivery functions required to unlock the new capabilities of Type-C including 100W power, 20Gbps bandwidth, reversibility and flexibility.

“Leaders in this market will launch USB Type-C products by the middle of this year,” said Gordon Hands, Director New Initiatives at Lattice. “We are providing ready-to-use, low power, miniature, cost-effective solutions that slash time-to-market and mitigate development risk.”

The three solutions offered by Lattice address both Cable Detect (CD) and Power Delivery (PD) functions and deliver:

CD/PD targeting chargers

CD/PD for devices such as laptops, docks, dongles hand-held industrial

CD/PD-Phy for devices such as smart phones and tablets

The downloadable reference designs include: Schematic; BOM; Pin-list; Bitstream; and Code to allow Policy Engine customisation. The designs are based on Lattice’s iCE40 ultra-low power, miniature and low cost FPGA families.
