CS4953xx Data Sheet
32-bit Audio Decoder DSP Family

1 Documentation Strategy
The CS4953xx data sheet describes the CS4953xx family of multichannel audio decoders. This document
should be used in conjunction with the following documents when evaluating or designing a system around the
CS4953xx family of processors.
The scope of the CS4953xx data sheet is primarily the hardware specifications of the CS4953xx family of
devices. This includes hardware functionality, characteristic data, pinout, and packaging information.
The intended audience for the CS4953xx data sheet is the system PCB designer, MCU programmer, and the
quality control engineer.
2 Overview
The CS4953xx DSP Family, together with Cirrus Logic’s comprehensive library of audio processing algorithms
enables the development of next-generation audio solutions. There are two classes of devices in the
CS4953xx DSP family:
CS4953x3 Class (ROM ID 3), comprising the CS495303 and the CS495313
CS4953x4 Class (ROM ID 4), comprising the CS495304 and the CS495314
The primary difference between the CS4953x3 and the CS4953x4 classes is the support of the DSP
Condenser application on the CS4953x4 class of products only. The 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 the DSP Condenser can be found in the
CS4953x4/CS497xx System Designer’s Guide.
Within each ROM ID class (3, 4), the breakdown into two devices per class (CS49530x and CS49531x) is
based on the differences between the internal memory size and DSP firmware supported. Essentially, the
audio processing features of the CS49531x are a superset of audio features available in the CS49530x.
Table 2, “Device and Firmware Selection Guide,” on page 6 provides details of the differences between the two
product classes.
Note: The CS495303/04/14 is available in a 128-pin LQFP package and the CS495313 is available in a 128-pin
or 144-pin LQFP package.
