CS7410-CM

CD/MP3/WMA Audio Controller

Cirrus Logic 

CS7410

sor communication

• Three 32-bit timers for I/O and other uses, with

programmable interval rates

• “Getbits” module accelerates peripheral stream

parsing

• Both hardware and software interrupts on data

or debug

2.2.4 Memory System

• Large internal SRAM (80 Kbyte) and internal

program ROM (256 Kbyte)

• Supports both Synchronous and EDO DRAM

(256 KBytes to 8 MBytes) for ESP

• Supports one bank of FLASH and ROM (up to

2 MBytes) for nonvolatile storage

• 4-, 8-, or16-bit data bus for DRAM, 8-bit data

bus for ROM

2.2.5 CD Interface

• Glueless interfaces to CD servo chip set, sup-

porting all standard CD formats

• Includes pattern matching hardware to support

fast ESP recovery

2.2.6 Audio Interface

• Supports 4 channels PCM, I2S connectivity at

up to 24 bits

• Flexible audio clocking scheme using internal

PLL and dividers, or external pins

• Simultaneous IEC-958 output with program-

mable channel status and user data

• Integrated sigma-delta (∆Σ) stereo audio mod-

ulator

2.2.7 External Interface

• 2-wire serial slave port, used for debug

• 3- or 4-wire synchronous serial master/slave

port for external controller or slave peripheral

• Separate synchronous serial master port opti-

mized for receiving CD sub-codes

• Up to 29 programmable bi-directional I/O

(GPIO) and up to 9 output only (GPO) pins

(some multiplexed with other peripherals)

• All pins defined as GPIOs can be used to re-

ceive edge or level detection interrupts.

• Pulse-width modulated (PWM) output pin can

be used to create simple ADC using low-cost

comparator (i.e., for battery voltage monitor)

2.2.8 System Functions

• Internal oscillator uses external crystal, or re-

ceives clock (i.e. 16.9 MHz) from CD servo

• Internal PLL generates any system clock fre-

quency, chip can run up to 90 MHz

• Includes clock divider and clock shutoff cir-

cuits for low power/sleep modes

• Advanced 0.18 micron CMOS technology,

runs off 1.8 V and 3.3 V

• All I/O pins are 3.3 V, with 5 V tolerance

• 100-pin MQFP package

• 100-pin LQFP package
