This is the manual for the microprocessor (ECU) that was involved in the Toyota "unexpected acceleration" case which is the only one I could find any details on.
It's a 32-bit risc processor with 64MB of program address space, and 4GB linear address space. Of course, this one is 10 years old at this point.
One article I read also point to the Freescale MC9S12XDP512 as a pretty common processing unit for current day ECUs. It's a 16-bit, 40Mhz main processor with a 80Mhz coprocessor, 32KB of ram, 512KB of Flash and 90 I/O pins.
Phones vs "old school" computers..

I've worked in IT for over a third of my life now, and FLOPS, MFLOPS, and GFLOPS still makes me giggle every damn time.
