Description
This device is a high-performance, fully
programmable DSP, suitable for a wide range of
applications and particularly for audio and sound
processing. It contains a 24-bit 50 MIPS DSP
core, several interfaces for control and data, plus
a configurable PLL.
LQFP44 (10x 10x 1.4mm)
The computational power and the memory
configuration make this device particularly
suitable for in car equalisation. This device will
offer the best trade-off between performance and
cost when coupled with the TDA7535, or other
devices of the same family. A library of sound
processing functions is available for this device;
some of these functions are: parametric equaliser,
cross over filters, acoustic delay, dynamic
compression, vol/bass/treble/fader, active
equalisation, Stereo spatial enhancement and
more.
