I understand not wanting to change processors.  But the

that it can be a cheaper part by letting you reuse the same hardware to
do different things at different times.  But just like with FPGAs,
there are very few designs that can take advantage of that.  Also, the
price advantage of this approach can be very minimal due to the extra
chip area requried to make the features programmable.  But with current
process geometries, processors often are pin count limited; they have
to be a certain size to have the pin connections.  It is not
automatically cheaper to have a smaller processor with the same number
of pins.


Rickman,

Without the reconfigurability, the PSOC would be just another 8-biter, as good as many 8-biters on the crowded market. The reconfigurability is a pure marketing feature created to raise the public interest to the part. There is no cost or performance advantages however this is somewhat different which may seem appealing.
