STMicroelectronics 

Typical applications

STi5202

The audio subsystem includes:

● Digital audio decoder

– Support for all the most popular audio standards including WMA-9, WMA-9 Pro,

MPEG-1 layer I/II, MPEG-2 layer II, MPEG-2 AAC, MPEG-4 AAC LC 2-

channel/5.1 channel MPEG-4 AAC+SBR 2-channel/5.1 channel, Dolby® Digital

EX, Pro Logic® II, MLP™ and DTS®

– PCM mixing with internal or external source and sample rate conversion

– 6- to 2-channel downmixing

– PCM audio input

– Independent multichannel PCM output, S/PDIF output and analog output

● Stereo 24-bit audio DAC for analog output

● IEC958/IEC1937 digital audio output interface (S/PDIF)

● CSS/CPxM copy protection hardware

Available interfaces include:

● External memory interface (EMI)

– 16-bit interface supporting ROM, flash, SFlash, SRAM, peripherals

– Access in 5 banks

– High speed synchronous mode for interconnecting two STi5202 devices
