Overview
VS1005g 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 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.
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.
VS1005g is offered in six different variants
(see Chapter 4 for details).
