Arasan’s SWI3S IP joins Arasan’s extensive MIPI IP portfolio which includes its Soundwire IP, CSI, DSI, CDPHY and DPHY IP.  Arasan is the industry’s first provider of IP for the MIPI standards and has been an executive member of the MIPI Association since 2005.

The MIPI SWI3S IP is used to connect digital audio components such as Digital Microphone, Audio Codecs, Amplifiers, Headset and docking audio, DSPs etc. on mobile devices.

Features of SoundWire I3S IP:

• Fewer Wires → Simplifies PCB layout 
• Lower Power → Ideal for battery-powered devices 
• High Bandwidth → Handles multi-channel high-res audio 
• Integrated Control + Audio → No separate control bus needed

Arasan’s SWI3S Manager IP and SWI3S Peripheral Controller Core IP implement the link protocol to communicate in half-duplex fashion to transfer the Audio streams and the Control information together. One or more SWI3S Peripheral IP can be connected specific to the application.

“Arasan is proud to announce the industry’s first SWI3S IP. Arasan’s offers a focussed portfolio of IP products and services targeting the Mobile SoC market and it is imperative to our business that we are the first while also ensuring compliance with the standards. We are proud to be first again with our SWI3S IP.” said Ron Mabry, VP of Sales at Arasan.
