VS1005 is a flexible audio platform device. It
is built around VS_DSP
4
, 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.
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.
Product is offered in six different variants. See
section 3. for details.
