I've spent the entire day scouring the web for microcontrollers with a
built-in J1850 BLDC. Finding these chips is not difficult; finding one
that is still current, however, seems to be much more difficult. So
far promising-sounding ones like the MC68HC908AS20, the MC68HC912B32,
and the MPC5200 are either no longer being sold or are "not
recommended for new designs."

Can anyone recommend a CURRENT chip, preferably one with an
inexpensive eval board and free/inexpensive development tools (this is
a hobby project, so cost is a big factor)?

Thanks for your help!

Call your Freescale Semiconductor rep and ask what they are currently
promoting. I think the MPCS65 and MPCS66 series should do what you want
and they are pretty high-powered 32-bit devices.

I think if it's a hobby project there should be no reason not to use a
product that is end-of-lifed. You aren't going to need to order a million
of them.

I think also that if you were designing a production device, there might
be a cost benefit in doing the J1850 stuff in software and bit-banging it.
This would be absolutely hellish to program, but cheap.
