ADSP-2156x SHARC Product Family Delivers Lowest Latency, Highly Deterministic Real-Time Audio Processing Performance

The ADSP-2156x series (ADSP-21562 / 21563 / 21565 / 21566 / 21567 / 21569) of processors are designed to provide immersive audio and sound experience in automotive and consumer/pro-audio applications. The ADSP-2156x audio processors are specifically targeted for applications that demand deterministic and low latency real-time audio processing including immersive 3D sound and personal audio zones, automotive active and road noise cancellation (ANC/RNC), voice-based user-interfaces and in-car communications (AEC/NR & microphone beamforming), engine sound synthesis (ESS) and electric vehicle warning sound systems (EVWSS/AVAS). Additional applications include professional audio and soundbars / home AVRs (with 3D Object and Multi-Channel Audio).

The ADSP-2156x family are single core 32-bit/40-bit/64-bit floating point processors based on SHARC+ DSP architecture, combining flexible audio connectivity and performance scalability with multiple pin compatible variants (from 400MHz to 1GHz) and several on-chip memory options.


ADI’s rapid prototyping hardware & software development tools enable solution developers to achieve fast time to market. Optimized software-based audio algorithms can be tuned for specific use cases for ease of solution design and reduced development effort.

The ADSP-2156x processors are available in 400-ball CSP_BGA (17mm x 17mm, 0.8mm pitch) and 120-lead LQFP package (14mm x 14mm) options in both automotive and consumer grades to provide design flexibility and enable thermally efficient compact designs across operating temperature range.
