Cirrus Logic has launched a music processor chip, which enables compressed-music players packed with 20h of content and up to retail for <$50.

The company's programmable CS7410 chip, which can support CD, MP3, and high-density WMA formats, will be upgradeable if additional audio compression formats gain sufficient acceptance, Cirrus said.

The CS7410 packs into a 100-pin LQFP or MQFP a 32-bit RISC core, a 16-bit audio DSP, an 18-bit delta-sigma DAC, a CD servo controller interface, a battery monitor, 256KB of ROM, and 80KB of RAM.

The chip delivers four-channel, 24-bit, 96kHz audio data and can easily be interfaced to external DACs and digital headphone amplifiers. A reference design is available. MP3 decoding is provided from 5Kbps to 640Kbps and WMA decoding from 5Kbps to 192Kbps.

Available now, the CS7410 is priced at $8.62 in quantities of 10,000.
