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_DSP4 processor 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.
