USB Type-C Interface IP for Lattice Semiconductor’s programmable logic
Lattice Semiconductor has four solutions, using its programmable devices alongside USB 3 chips and power management ICs, that allow the rapid implementation of the recently released USB Type-C standard. These 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 20 Gbps of bandwidth and the flexibility to repurpose the connector and cable to deliver other signals, such as Display Port and HDMI.

“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 at Lattice.
Through its programmable logic based approach, Lattice says it can implement USB Type-C’s critical PD, CD and VDM functions in a manner that maximises the ability to respond to changing requirements while minimising power compared to solutions that primarily use a microprocessor for implementation.
The Lattice solutions can be implemented in a variety of packages from QFN, for easy assembly using low cost PCBs, to 0.4 mm BGAs for form-factor-constrained designs. Pricing for the multimillion unit volumes typical of consumer mobile designs is below $1.
