VS1005g Datasheet

VS1005g - Audio Processing Platform IC

Analog Hardware Features

Applications

• Three channels of 24-bit audio ADC

• Two 24-bit audio DACs

• Portable recorders

• Digital docking stations

• MP3 players

• Stereo earphone driver for 30 Ω load

• Internal microphone ampliﬁers

• Stereo FM radio receiver with RDS

• 10-bit ADC, 3-5 external inputs

• Operation from single power supply,

four programmable internal regulators

• Internet radio

• Wireless headphones

• Audio co-processor

Overview

VS1005g is a ﬂexible audio platform device.

It is built around VS_DSP⁴, which is a power-

ful DSP (Digital Signal Processor) core. The

digital interfaces provide ﬂexible access to ex-

ternal devices in standalone applications and

ﬂexible digital audio data inputs and outputs

when the device is used as an audio signal

processor in more complex systems. The ana-

log interfaces provide high-quality audio in-

puts and outputs, and the control ADC can

be used for example for interfacing a resis-

tive touch panel.

Digital Hardware Features

• 100 MIPS VS_DSP⁴processor core

• 128 KiB program RAM (32 KiWord)

• 128 KiB data RAM (2×32 KiWord)

• Protected 8 Mi-bit FLASH (Optional)

• USB 2.0 Hi-Speed (480 Mbit/s)

Device / Host

• I2S and SPDIF digital audio interfaces

• NAND FLASH interface with EEC

• SD Card interface

• 2 SPI bus interfaces

• 10BaseT Ethernet controller

• UART interface

VS1005g has an embedded FLASH mem-

ory of 8 Mi-bits (1 MiByte) for customization

by VLSI, customers or third parties. The ﬁrm-

ware and hardware are designed to prevent

access to the embedded FLASH in protected

mode. After FLASH memory programming

VS1005g can be booted from it as a fully cus-

tomized stand-alone audio processor.

• All digital pins are user conﬁgurable for

general purpose IO

• Flexible clock selection, default opera-

tion from 12.288 MHz

• Internal PLL clock multiplier for digital

logic

• RTC with battery backed memory

• Reed-Solomon error correction

• HW debug support with VSIDE via JTAG

VS1005g is offered in six different variants

(see Chapter 4 for details).

Firmware and VSOS Features

• Decoders: MP3, WMA, Ogg Vorbis, AAC,

HE-AAC, FLAC, WAV PCM

• Encoders: MP3, Ogg Vorbis, WAV PCM

• File I/O for SD cards and NAND ﬂash

• FM tuner and RDS decoder

• USB host and slave libraries

• Graphical display with resistive touch panel

• Extensive audio DSP library

• IP stack of Ethernet

• Flexible boot options

• Pre-emptive multitasking

• Easy-to-write software interface with VSIDE

Note: All VSOS features not available yet.
