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.

2.1 Migrating from CS4953x3 to CS4953x4
• The recommended way to boot the DSP for normal operation is “master boot”. Refer to Chapter 1 of the
CS4953x4/CS4970x4 System Designer’s Guide. CS4953x4 will support slave boot mode as well (used
for programming the serial flash with the DSP code, through the SCP2 port).
• CS4953x4 DSPs are only available in 128 pin package.
• The serial flash chip select pin used is pin 14 (GPIO0). Cirrus Logic recommends that at least an 8-Mbit
serial Flash device be used. Refer to CS4953x4/CS4970x4 System Designer’s Guide for a list of Flash
types that are currently supported
• CS4953x4 DSP family supports DSP Condenser and DSP Manager API for run-time control/host
communication. Please refer to CS4953x4/CS4970x4 System Designer’s Guide for details.
2.2 Licensing
Licenses are required for all of the 3rd party audio decoding/processing algorithms listed below, including the
application notes. Please contact your local Cirrus Sales representative for more information.
3. Code Overlays
IN
AR
Y
The suite of software available for the CS4953xx family consists of an operating system (OS) and a library of
overlays. The overlays have been divided into three main groups called Decoders, Mid-processors, and Postprocessors. All software components are defined below:
1. OS/Kernel - Encompasses all non-audio processing tasks, including loading data from external memory,
processing host messages, calling audio-processing subroutines, error concealment, etc.
2. Decoders - Any Module that initially writes data into the audio I/O buffers, e.g. AC-3®, DTS, PCM, etc. All the
decoding/processing algorithms listed below require delivery of PCM or IEC61937-packed, compressed data
via I2S- or LJ-formatted digital audio to the CS4953xx.
3. Matrix-processors - Any module that processes audio I/O buffer PCM data in-place before the Postprocessors. Generally speaking, these modules alter the number of valid channels in the audio I/O buffer
through processes like Virtualization (nÖ2 channels) or Matrix Decoding (2Ön channels). Examples are Dolby
ProLogic IIx and DTS Neo:6.
PR
EL
IM
4. Post-processors - Any module that processes audio I/O buffer PCM data in-place after the Mid-Processors.
Examples are Bass Management, Audio Manager, Tone Control, EQ, Delay, Customer-specific Effects, Dolby
Headphone/Virtual Speaker, etc.
The overlay structure reduces the time required to reconfigure the DSP when a processing change is
requested. Each overlay can be reloaded independently without disturbing the other overlays. For example,
when a new decoder is selected, the OS, mid-, and post-processors do not need to be reloaded — only the
new decoder (the same is true for the other overlays).
Table 2 below lists the firmware available based on device selection. Please refer AN288 CS4953xx Firmware
User’s Manual for the latest listing of application codes and Cirrus Framework™ modules available.

4. Hardware Functional Description
4.1 DSP Core
The CS4953xx is a dual-core DSP with separate X and Y data and P code memory spaces. Each core is a
high-performance, 32-bit, user-programmable, fixed-point DSP that is capable of performing two memory
access control (MAC) operations per clock cycle. Each core has eight 72-bit accumulators, four X- and four Ydata registers, and 12 index registers.
Both DSP cores are coupled to a flexible DMA engine. The DMA engine can move data between peripherals
such as the digital audio input (DAI) and digital audio output (DAO), external memory, or any DSP core
memory, all without the intervention of the DSP. The DMA engine offloads data move instructions from the DSP
core, leaving more MIPS available for signal processing instructions.
CS4953xx functionality is controlled by application codes that are stored in on-board ROM or downloaded to
the CS4953xx from a host mcu or external FLASH/EEPROM. Users can choose to use standard audio
decoder and post-processor modules which are available from Cirrus Logic.
4.1.1 DSP Memory
IN
AR
Y
The CS4953xx is suitable for Audio Decoder, Audio Post-processor, Audio Encoder, DVD Audio/Video Player,
and Digital Broadcast Decoder applications.
Each DSP core has its own on-chip data and program RAM and ROM and does not require external memory
for any of today’s popular audio algorithms including Dolby Digital Surround EX, AAC Multichannel, DTS-ES
96/24, and THX Ultra2.
The memory maps for the DSPs are as follows. All memory sizes are composed of 32-bit words.

4.1.2 DMA Controller
The powerful 12-channel DMA controller can move data between 8 on-chip resources. Each resource has its
own arbiter: X, Y, and P RAM/ROMs on DSP A; X, Y, and P RAM/ROMs on DSP B; external memory; and the
peripheral bus. Modulo and linear addressing modes are supported, with flexible start address and increment
controls. The service interval for each DMA channel as well as up to 6 interrupt events, is programmable.

4.2 On-chip DSP Peripherals
4.2.1 Digital Audio Input Port (DAI)
The 12-channel (6 line) DAI port supports a wide variety of data input formats. The port is capable of accepting
PCM, IEC61937, or DSD. Up to 32-bit word lengths are supported. Up to 6 channels of DSD are supported and
internally converted to PCM before processing.
The port has two independent slave-only clock domains. Each data input can be independently assigned to a
clock domain. The sample rate of the input clock domains can be determined automatically by the DSP, which
off-loads the task of monitoring the S/PDIF receiver from the host. A time-stamping feature allows the input
data to be sample-rate converted via software.
4.2.2 Digital Audio Output Port (DAO)
IN
AR
Y
There are two DAO ports. Each port can output 8 channels of up to 32-bit PCM data. The port supports data
rates from 32 kHz to 192 kHz. Each port can be configured as an independent clock domain in slave mode, or
the ratio of the two clocks can be set to even multiples of each other in master mode. The two ports can also be
ganged together into a single clock domain. Each port has one serial audio pin that can be configured as a 192
kHz S/PDIF transmitter (data with embedded clock on a single line).
Note: Only one S/PDIF transmitter pin is available in the 128-pin package.
4.2.3 Serial Control Port 1 & 2 (I2C™ or SPI™)
There are two on-chip serial control ports that are capable of operating as master or slave in either I2C or SPI
modes. SCP1 defaults to slave operation. It is dedicated for external host-control and supports an external
clock up to 50 MHz in SPI mode. It is present in both the 144- and 128-pin packages. This high clock speed
enables very fast code download, control or data delivery. SCP2 defaults to master mode and is dedicated for
booting from external serial Flash memory or for audio sub-system control. SCP2 does not include the
SCP2_BSY# pin in the 128-pin package.
4.2.4 Parallel Control Port
PR
EL
IM
The CS4953xx parallel port supports both Motorola® and Intel® interfaces. It can be used for both control and
data delivery. The parallel port pins are multiplexed with serial control port 2 and are available in the 144-pin
package.
4.2.5 External Memory Interface
The external memory interface controller supports up to 128 Mbits of SDRAM, using a 16-bit data bus.
4.2.6 GPIO
Many of the CS4953xx peripheral pins are multiplexed with GPIO. Each GPIO can be configured as an output,
an input, or an input with interrupt. Each input-pin interrupt can be configured as rising edge, falling edge,
active-low, or active-high.
4.2.7 PLL-based Clock Generator
The low-jitter PLL generates integer or fractional multiples of a reference frequency which are used to clock the
DSP core and peripherals. Through a second PLL divider chain, a dependent clock domain can be output on
the DAO port for driving audio converters. The CS4953xx defaults to running from the external reference
frequency and can be switched to use the PLL output after overlays have been loaded and configured, either
through master boot from an external serial FLASH or through host control. A built-in crystal oscillator circuit
with a buffered output is provided. The buffered output frequency ratio is selectable between 1:1 (default) or
2:1.
4.3 DSP I/O Description
4.3.1 Multiplexed Pins
Many of the CS4953xx pins are multi-functional. For details on pin functionality please refer to the CS4953xx
Hardware User’s Manual.

1. CS4953xx has two Digital Audio Output modules having similar signal names ending in 1 and 2. Both DAO ports
share a common MCLK but have independent SCLKs and LRCLKs.
2. Master mode timing specifications are characterized, not production tested.
3. Master mode is defined as the CS4953xx driving both DAO_SCLK, DAO_LRCLK. When MCLK is an input, it is
divided to produce DAO_SCLK, DAO_LRCLK.
4. This timing parameter is defined from the non-active edge of DAO_SCLK. The active edge of DAO_SCLK is the
point at which the data is valid.
5.Slave mode is defined as DAO_SCLK, DAO_LRCLK driven by an external source.
