4 / 36 page CS4953xx Data Sheet 32-bit Audio Decoder DSP Family 4 Copyright 2009 Cirrus Logic DS705PP5 1. Documentation Strategy The CS4953xx Datasheet 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 Datasheet 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. 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 Designers’ Guide. Within each ROM ID class (3, 4), the breakdown into 2 devices per class (CS49530x, 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 that the CS495303/04/14 is available in a 128-pin QFP package and the CS495313 is available in either a 128-pin or 144-pin QFP package. Table 1.
