I got a data sheet in the mail recently from Dallas Semiconductor about
their MAXQ3120 microcontroller. It says the following:
"Give a group of engineers an ADC, and someone will discover how to record
voice with it. But the MAXQ3120 can do much more than simply record sound.
Coupled with user-interface components and an inexpensive NAND flash
memory, the MAXQ3120 becomes the core of a full-featured voice recorder
It then goes on to give some engineering details. This particular device
is MUCH faster than a PIC.
I think I am going to get one or two of these critters and experiment.
