Yamar’s Innovation
Replacing Copper wires with Silicon
• Small size silicon that competes with cost of wires
• Transparent to existing protocols (UART/LIN, CAN, SPI)
• Robust and reliable byte orientated communication
over noisy powerline using our unique modulation

AC-DC BUS Benefits
• Saves weight, space and improve reliability of wires in vehicles,
home appliances, etc.
• Simple to integrate, allowing new design concepts
• Same silicon for different products (Cars, Refrigerators, Washing
Machines, Air-conditioners, etc.
• Sub network for Internet of Things (IoT)
• Galvanic Isolation between zones (Renewal Energy, EV batteries)
• Price competes with the cost of wires
