Another idea for a 8 pin ARM: the MSP430 is able to decode and encode DTMF
(but timing is near the limit). The ARM7 is good for many applications that
need filtering, FFT's, and other DSP functions. For a simple DTMF decoder I
only need 2 pins. A small software radio (demodulation of IF in software)
could also work with 4 pins (IF-in, speaker-out, some keys). (e.g. DRM or DAB
but I have no idea, what power is needed to decode DRM).
