DSPA56367AG150 Overview
A Digital Signal Processor (DSP) is a specialized microprocessor whose architecture is optimized for the mathematical operations common in real-time signal processing - multiply-accumulate (MAC) units, Harvard memory buses, and deterministic instruction cycles. Within the broader taxonomy, the DSPA56367 belongs to the category: DSP -> programmable CMOS DSP -> audio DSP -> embedded processor -> semiconductor IC. It sits alongside general-purpose microcontrollers but trades flexibility for raw signal-chain throughput and deterministic latency, which is critical when decoding compressed audio streams or running noise-cancellation loops.
Key features include a 24-bit data word, up to 150 MIPS sustained throughput, dedicated audio I/O channels, a host interface (HPI/SCI), serial audio interface (SAI/ESSI), and a memory controller that supports external SDRAM and SRAM. The 144-pin LQFP-20x20 package provides ample I/O for multi-channel audio designs while using a standard surface-mount footprint and reflow-compatible lead finish.
Architecturally, the DSP56367 uses a dual Harvard architecture with four internal data buses and one program bus, enabling single-cycle MAC operations. The 24-bit fixed-point data path provides extended dynamic range compared with 16-bit DSPs, reducing the need for intermediate scaling and yielding better headroom for audio codecs such as Dolby Digital, DTS, and AAC decoding.
Typical applications include AV receivers, soundbars, automotive head units, professional audio mixers, and effects processors. Designers choose this family when deterministic real-time audio performance is required at production volumes.
When designing with this part, ensure the JTAG/OnCE debugging interface is accessible on the PCB test fixture, and that the 3.3V core and I/O rails are sequenced correctly to avoid latch-up during brown-out events.

Typical Applications
DSPA56367AG150 is suitable for 7 applications: AV Receiver Audio Decoding, Soundbar Signal Processing, Automotive Head Unit Audio DSP, Professional Audio Effects Processor, Voice Processing / VoIP Endpoint, Audio Test & Measurement Equipment, Multimedia Streaming / Set-Top Box Audio Sub-system.
AV Receiver Audio Decoding
The DSPA56367AG150's 150 MIPS throughput and 24-bit fixed-point data path make it ideal for multi-channel AV receiver audio decoding where Dolby Digital, DTS, and AAC codecs must be processed in real time. The part's dual Harvard architecture with single-cycle MAC operations decodes compressed bitstreams with deterministic latency, while the dedicated ESSI/SAI audio serial ports feed the audio DAC stage. Placed on the main audio processing board, the DSP replaces discrete decoder ASICs and gives manufacturers firmware-based upgrade paths for new codec formats. The 144-pin LQFP-20x20 footprint allows dense multi-layer PCB designs used in slim AV receiver chassis.
Recommended
Soundbar Signal Processing
In soundbar designs the DSPA56367AG150 handles bass management, time alignment, room correction, and virtual surround processing at 150 MIPS. The 24-bit data word preserves dynamic range for psychoacoustic algorithms, while the host interface (HPI/SCI) lets the main SoC stream PCM or compressed audio into the DSP for further processing. Versus fixed-function DSPs, the programmable DSP56300 core allows firmware-upgradeable audio DSP modes, important in a market where consumers expect post-purchase feature enhancements. The LQFP-144 footprint is reflow-compatible with standard SMT lines used for soundbar production.
Recommended
Automotive Head Unit Audio DSP
Automotive head units use the DSPA56367AG150 for hands-free voice processing, noise cancellation, and equalization, all of which require deterministic real-time audio DSP performance. The 150 MIPS core handles multi-mic beamforming and echo cancellation at automotive ambient levels, while the HPI interface connects to the head-unit SoC for codec selection and volume control. Compared with general-purpose MCUs, the fixed-point 24-bit DSP56300 family offers a deterministic instruction cycle that real-time audio loops demand. The LQFP-144 footprint is a known and reflow-friendly automotive grade package.
Recommended
Professional Audio Effects Processor
Studio effects processors and guitar pedals use the DSPA56367AG150 to run reverb, delay, chorus, and dynamics algorithms with the dynamic range demanded by professional audio. The 24-bit data path keeps quantization noise below the studio noise floor, while the dual Harvard bus handles the parallel coefficient updates required for FIR filter effects. The 150 MIPS throughput is sufficient to run multiple simultaneous effects in a multi-channel signal path. The standard LQFP-144 20x20 footprint simplifies panel layout for OEM pro-audio module builders.
Recommended
Voice Processing / VoIP Endpoint
VoIP and conference phones use the DSPA56367AG150 for acoustic echo cancellation (AEC), noise suppression, and gain control across multiple microphones. The 150 MIPS core can handle AEC tail lengths of 100-200 ms in real time on 16 kHz sampled voice streams, and the DSP56300 deterministic interrupt latency ensures audio glitches never break VoIP sessions. The H08 parallel host interface allows the main VoIP SoC to push voice buffers into DSP memory with low overhead, while the ESSI ports deliver processed audio to the codec DAC. Power consumption is moderate at 3.3V core, fitting the thermal envelope of desk VoIP phones.
Recommended
Audio Test & Measurement Equipment
Audio test benches, signal generators, and analyzers use the DSPA56367AG150 to generate precise test waveforms (sine, pink noise, chirp) and to perform real-time FFT-based audio analysis. The 24-bit data path and 150 MIPS throughput support measurement-grade dynamic range above 100 dB, suitable for production-line audio DUTs. The JTAG/OnCE debug interface allows factory firmware updates and in-system test hooks without NRE cost. Compared with PC-based test, the DSP gives deterministic real-time response with no OS jitter.
Recommended
Multimedia Streaming / Set-Top Box Audio Sub-system
Set-top boxes and streaming media players route PCM and compressed audio (Dolby Digital Plus, AAC LC) through the DSPA56367AG150 for decoding and downmix to the consumer's speaker configuration. The 150 MIPS core handles 5.1-channel downmix in real time, while the external memory controller streams audio bitstreams from the SoC's DDR. Versus a pure software decoder on the application processor, the DSP offload frees CPU cycles for UI/streaming work and gives more deterministic audio latency. LQFP-144 (20x20 mm) is a standard chassis footprint for set-top mainboards.

Key Differentiators
- Same die and identical 150 MIPS performance across grade suffixes (vs DSPB56367AG150)
- 150 MIPS sustained throughput with deterministic single-cycle MAC (vs General-purpose MCU for audio DSP)
- Backward compatibility within DSP56300 family at 150 MHz speed bin (vs Lower-speed grades (e.g., 100/120 MHz))
Design Notes
The DSPA56367AG150 operates from a 3.3V supply for both core and I/O rails. Decouple each VDD/VSS pair with a 0.1uF ceramic capacitor placed within 3 mm of each pin pair, plus a bulk 10uF tantalum or ceramic near the package. Brown-out behavior is documented in the NXP DSP56367 datasheet (Rev. 2.1, 1/2007); ensure VDD reaches a stable level before the host SoC begins driving the HPI bus to avoid bus contention.
The 144-pin LQFP-144 20x20 mm package has a 0.5 mm lead pitch; route one signal trace between pads on inner layers to escape the pin field without dog-bone fanouts. Place the JTAG/OnCE header at the PCB edge for in-system firmware updates during production test. ESD protection diodes are recommended on all externally-accessible audio signals (ESSI/SAI pins that connect to jacks).
Do not assume the 'A', 'B', and 'C' suffixes represent performance differences - they are ordering/temperature/screening grade identifiers per NXP/Freescale ordering scheme. Always verify the exact grade against the DSP56367 datasheet (Rev. 2.1, 1/2007) before placing volume orders. Stock has been observed at 34380 units Sep 07, 2026 on Octopart, but NXP reports 99-week lead times and NRND status - plan alternates now.
