Has anyone else ever desired a 3-pin PIC, or
better still, ever seen/used a 3-pin micro??

I'm imagining something the size of a TO-92 (small
plastic transistor) or 3-pin SMT device, with
2 power pins and a single I/O pin.

A simple pullup resistor on the I/O pin would allow
it to transmit and receive digital at the same time
on the one pin, so it could drive a constant PWM
signal out (to operate a motor or SMPS etc), and
at the same time receive serial in from any source.

Internally it should have a precise osc with on-chip
resonator so it can be used as a programmable
real-time clock, or a timed controller system.
And some internal eeprom... How much was it again
to get a batch of custom chips made?? :o)
