Interesting. That's what the Future rep told me about a year ago.

"Please note that the complete listing of MAC7101 devices is available 
only to Tier 1 Automotive vendors."

"Please note that the complete listing of MAC7111 devices is available 
only to Tier 1 Automotive vendors."

It's a BIG red flag anyway.

This is rather short on specifics, like how many processors you expect 
to use, and the task partitions ?.
For just PWM readout, (frequency?, Duty range ?) you can use 6 channels 
of capture, and derive the edge times - you do not have to use 6 timers.

So, that allows some small 8 bit uC as well, eg the Silabs C8051F410
has a lot of usefull peripherals for the coal-face stuff for positioning.
