enables the development of next-generation audio solutions. There are two classes of devices in the
CS4953xx DSP family:
Condenser application on the CS4953x4 class of products only. DSP Condenser is a tool set that enables the
DSP to automatically boot and configure itself from an external Serial FLASH, thus reducing the traditional
heavy loading on the part of the system microcontroller. Because of the design time savings, enhanced tools
support, and better performance associated with the CS4953x4 product set, Cirrus Logic recommends that the
CS4953x4 family be used for all new designs. More information on DSP Condenser can be found in the
CS4953x4/CS497xx System Designer’s Guide.

The CS4953xx Data Sheet describes the CS4953xx family of multichannel audio decoders. This document
The scope of the CS4953xx Data Sheet is primarily the hardware specifications of the CS4953xx family of
The intended audience for the CS4953xx Data Sheet is the system PCB designer, mcu programmer, and the
The CS4953xx DSP Family, together with Cirrus Logic’s comprehensive library of audio processing algorithms
The primary difference between the CS4953x3 and the CS4953x4 classes is the support of the DSP
Within each ROM ID class (3, 4), the breakdown into 2 devices per class (CS49530x, CS49531x) is based on
Note that the CS495303/04/14 is available in a 128-pin QFP package and the CS495313 is available in either
• CS4953x3 Class (ROM ID 3), comprising the CS495303 and the CS495313
• CS4953x4 Class (ROM ID 4), comprising the CS495304 and the CS495314
