Overview
VS1005 is a flexible audio platform device. It
is built around VS_DSP4, which is a powerful
DSP (Digital Signal Processor) core. The
digital interfaces provide flexible access to external
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 analog
interfaces provide high quality audio inputs
and outputs and the control ADC can
be used for example for interfacing a resistive
touch panel.
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 prevent
access to the FLASH in protected mode.
After programming, VS1005 can be booted
from the embedded memory as a fully customized
stand-alone audio processor.
Product is offered in six different variants. See
section 3. for details.
