Arasan Launches MIPI SWI3S Manager IP and Peripheral Controller IP

Arasan Chip Systems, prominent in the provision of semiconductor Intellectual Property (IP) for mobile and automotive System on Chips (SoCs), has announced a groundbreaking advancement in the industry. On August 6, 2025, the company introduced the first-ever MIPI SWI3S Manager IP and SWI3S Peripheral IP cores aimed at enhancing digital audio connectivity in mobile devices.

The Innovation Behind SWI3S

The introduction of the SWI3S IP represents a significant milestone in audio technology for mobile devices. Designed to cater to the needs of compact and efficient audio setups, the SWI3S IP core maintains a low gate count while aiming for low latency and power consumption. This makes it ideal for modern applications, particularly for digital microphones and audio codecs used in smartphones and other connected devices.

Arasan's SWI3S Manager IP facilitates seamless communication in a half-duplex manner, allowing audio streams and control information to be transferred simultaneously, thereby simplifying circuit designs and reducing the number of required wires. This innovation enables mobile devices to support multi-channel, high-resolution audio without complicating the PCB layout—a common challenge in the development of compact consumer electronics.

Extensive MIPI IP Portfolio

This new MIPI SWI3S IP joins Arasan's extensive collection of MIPI IP solutions, which already includes SoundWire IP, Camera Serial Interface (CSI), Display Serial Interface (DSI), and various PHY IP components. Since its early inception at the MIPI Association back in 2005, Arasan has consistently targeted excellence and leadership in the MIPI standards, providing robust solutions for various applications in the mobile sector.

Key Features of the MIPI SWI3S IP

1. Simplified Design: The reduced wire requirement allows for a more streamlined PCB layout, facilitating the design process for manufacturers.
2. Low Power Consumption: Engineered to function efficiently in battery-powered devices, the SWI3S IP is a perfect fit for today's mobile technology trends focused on longevity and energy efficiency.
3. High-Bandwidth Capacity: Capable of handling multi-channel high-resolution audio, this IP addresses the demands of modern audio technologies.
4. Integrated Control Features: Eliminating the need for a separate control bus, the integrated system allows for reduced complexity and increased reliability in audio management.

Strategic Market Positioning

Ron Mabry, VP of Sales at Arasan, expressed the company’s pride in launching the first SWI3S IP, noting their continuous commitment to the mobile SoC market. “It is imperative for our business to lead within our industry while ensuring compliance with established standards. We are thrilled to again pioneer with the introduction of our SWI3S IP,” he said.

Arasan is well known for its high-quality, proven silicon solutions, having shipped over a billion chips integrated with their IP. Their Total IP Solutions encompass not just digital IP but also Analog Mixed Signal PHY IP, Verification IP, hardware development kits (HDK), and software support.
