Lattice Semiconductor has announced four solutions that allow the rapid implementation of the recently released USB Type-C standard. These products have already been adopted by some customers, and Lattice will offer demonstrations during the USB 3.1 Developers’ Day, held in Singapore on 19^th and 20^th November.

Lattice’s four standardised solutions provide manufacturers with a range of options for meeting several of USB Type-C’s key capabilities, including Power Delivery (PD) negotiation, Cable Detection (CD) and Vendor Defined Messaging (VDM). These functions enable USB Type-C to deliver up to 100W of power, support in excess of 20Gb/s of bandwidth and the ability to utilise the connector and cable to deliver other signals, such as Display Port and HDMI.

Through its programmable logic-based approach, Lattice can implement USB Type-C’s critical PD, CD and VDM functions in a manner that maximises the ability to respond to changing requirements, whilst minimising power compared to solutions that primarily use a MPU for implementation.

“Manufacturers are quickly adopting USB Type-C in recognition of its compelling advantages and Lattice is enabling them to develop their USB Type-C solutions with the company’s low-cost and low-power programmable technology,” said Keith Bladen, Marketing Vice President, Lattice. “Developers are enjoying the time-to-market acceleration and flexibility that the Lattice programmable solutions can deliver to this emerging application area.”

The Lattice solutions can be implemented in a variety of packages from QFN, for easy assembly using low cost PCBs, to 0.4mm BGAs for form factor constrained designs. Pricing for the multimillion unit volumes typical of consumer mobile designs is below $1.00.
