Overview
VS1005 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 stand alone application 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 kB program RAM (32 kWord)
• 128 kB data RAM (64 kWord)
• Protected 8 Mbit FLASH (Optional)
• USB 2.0 High Speed (480 Mbit/s) De-
vice/Host
• I2S and SPDIF digital audio interfaces
• NAND FLASH interface with EEC
• SD Card interface
• 2 SPI bus interfaces
• 10BaseT Ethernet controller
• UART interface
VS1005 has an embedded FLASH memory
of 8 Mbits (1 MBytes) for customization by
VLSI, customers or third parties. The firmware
and hardware are designed to completely pre-
vent access to the FLASH in protected mode.
After programming, VS1005 can be booted
from the embedded memory 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 support for debug with VSIDE via
Product is offered in six different variants. See
section 3. for details.
