AKM launches new automotive audio DSPs
featuring triple HiFi 5 CPUs with hardware accelerators
and support for DSP Concepts' Audio Weaver

Asahi Kasei Microdevices Corporation (AKM) has developed the AK702x, a series of pin-compatible audio DSPs featuring up to three HiFi 5 cores.  These new devices were designed to take the in-car audio and voice experience to the next level.  Samples are scheduled to be available in the second quarter of 2026.

AKM has partnered with DSP Concepts, Inc. (DSP Concepts), a global market leader in the field of embedded audio software, to bring support for the Audio Weaver platform to the AK702x family. This integration has resulted in a flexible and scalable audio and voice application development environment and connects system designers to a rich ecosystem of 3rd party audio algorithms and providers that are already available on Audio Weaver.

AKM’s AK702x devices allow for great flexibility in the creation of advanced automotive infotainment systems. The AK7020’s triple HiFi 5 core configuration allows for simultaneous high-resolution audio processing on one core and voice processing, in addition to other features, on the others.  Since the HiFi 5 is a C-programmable DSP, users may elect to use multiple cores with Audio Weaver, or mix and match, using the other cores to run other custom audio algorithms. The AK702x family’s flexible clocking options and rich I/O support are suited for even the most complex audio systems, and provides scalable, pin-compatible solutions for more straight-forward system variants.
