Product Overview
CS49844A-CQZ is a quad-core 32-bit audio DSP from Cirrus Logic. It fully decodes Dolby Atmos, DTS:X and other lossless surround audio, with integrated large on-chip RAM to run algorithms without external memory. This NRND discontinued chip is supplied with limited stock, packaged in 144-LQFP for home theater, car audio and high-end soundbar equipment.
Core Advantages
Quad-Core 32-bit Fixed-Point DSP
Four independent cores process decoding, EQ and post-processing in parallel with low latency.
Full HD Surround Audio Decoding
Built-in decoding for mainstream lossless audio formats, eliminating extra decoding chips.
Integrated Large On-Chip Memory
Ample internal RAM/ROM cuts BOM cost and saves PCB layout space.
Multi Standard Digital Interfaces
Supports I2S, SPDIF, I2C and SPI for easy connection with MCU and audio peripherals.

Frequently Asked Questions
Q1: Why CS49844A-CQZ is not recommended for new designs?
A1: It is marked NRND by Cirrus Logic and out of mass production. Only limited leftover stock exists on market. Choose newer DSP chips for new projects.
Q2: What benefits does quad-core DSP bring?
A2: Four cores process decoding, EQ and sound mixing simultaneously, no audio lag for multi-channel HD audio.
Q3: What does suffix CQZ mean?
A3: Lead-free RoHS 144-LQFP commercial package, 0℃~70℃ operating temp, fits standard SMT soldering.
Q4: Does this chip require external memory?
A4: No. Built-in large RAM & ROM supports all audio algorithms without extra memory chips.
Q5: Are there compatible replacement chips?
A5: Contact our sales engineer for long-lifecycle Cirrus Logic audio DSP alternatives with full function compatibility.
Q6: Is the spot stock stable for bulk orders?
A6: Stock is limited due to EOL. Confirm inventory with us before placing large orders.
Q7: Can I get free samples for testing?
A7: Small test samples are available, submit inquiry form to apply for sample cost and shipping fee details.
Q8: Can this model work under industrial low temperature?
A8: Only commercial grade 0℃~70℃, not suitable for industrial equipment with wide temperature demand.
Q9: What control interfaces does this DSP support?
A9: Compatible with I2S, SPDIF, I2C and SPI to connect MCU, HDMI receiver and other audio modules.
