It helps to reduce development time, eliminating the need for stack integration and additional software and firmware development

With the increasing reliance of connected vehicles on Ethernet for network connectivity, smart technology is helping developers to streamline infotainment system development and quickly adapt to manufacturers’ evolving requirements.

For this, the LAN9360, a single chip Ethernet controller with embedded protocols has been introduced as an audio endpoint solution for AVB, facilitating interconnection of a vehicles’ infotainment devices including speakers, amplifiers, microphones, navigation systems, radio tuners and smart headrests with Ethernet AVB.

The LAN9360 bridges audio between Ethernet AVB and Inter-IC Sound (I2S), Time Division Multiplexing (TDM) and Pulse Density Modulation (PDM) local audio interfaces. It completely supports audio transmission over Ethernet AVB, including generalised Precision Time Protocol (gPTP), timestamping, transport protocols and content protection with High-bandwidth Digital Content Protection (HDCP).

It also supports secure boot and remote updates over Ethernet. Unlike other Ethernet bridging networking solutions that require System-on-Chip (SoC) microcontrollers (MCUs) plus third-party software stacks, the LAN9360 endpoint device requires no software integration, enabling designers to configure the device simply and quickly to manufacturers’ unique audio and networking requirements.

The device is validated to the IEEE 802.1BA-2011, IEEE 802.1AS, IEEE1722 and IEEE1733 specifications for Ethernet networks and is certified to the standards for AVB interoperability and reliability established by the Avnu Alliance consortium.

“In looking for an AVB solution for our Automotive Remote Tuners products, the LAN9360 allowed us to develop on a trusted platform quickly, without changing our current software,” said Pierrick Labeau, Research & Development Manager, FIAMM Horn & Antennas – Elettra 1938 Group.

“This endpoint controller is a single smart chip for Ethernet interoperability in infotainment systems,” said Matthias Kaestner, vice president, Automotive. “In today’s rapid-pace design environment, this out-of-the-box device gives engineers a quick start to development and allows them to avoid months of engineering work and technical risks involved in coding or engaging third-party integrators.”

Microchip’s The LAN9360 endpoint device is now available from Microchip Technology in a 100-Thin Profile Fine Pitch Ball (TFBGA) package option. Also available is a development board and Microchip’s MPLAB Network Creator for configuring the LAN9360 using an intuitive graphical user interface.
