    Infineon TC1796 pin locations on the MSD80 DME

    I finally got around to tracing out some of the BGA pins on the TC1796 back to various locations on the DME circuit board. Maybe someone will find this information as useful as I do.

    I haven't finished tracing everything out yet, so this image is a work in progress, I'll probably replace it with a better looking picture once I have everything located.

    So here are some pins that may be of interest...

    ASC0 is the asynchronous serial port, BRKIN is used for the various boot modes. Boot modes are set via HWCFG[3:0]. The TC1796 datasheet explains the boot configurations.

    HWCFG[2] and [3] are located on the other side of the board, I'll add a picture of that later on.

    If you can leave black marks on a straight from the time you exit a corner till the time you brake for the next turn....... Then, you have enough horsepower.

    wow great job, looks like a hell of a task to put trace this circuit out. Do you have any goals after you accomplish this?

    I've kind of lost interest in the ideas I had for the MSD80, but figured since I already spent time researching and tracing things out I figured I'd share some of it. Maybe it'll help people with other ideas they might have.

    Supposedly you can disable protection on the chip in ASC/BSL mode, if I get really bored some night I was thinking of dumping the memory from the chip just for fun.

    Now that I'm on a computer that isn't a POS, I've made a more readable version of the image.

    I'll update it at this URL: http://roycormier.net/images/projects/msd80_pins_1.jpg

    Lots of good work Roy you should continue to pursue mapping out this ECU, it can benefit a lot of people.

    Sure, the processor side of the board is here: http://roycormier.net/images/project...NSIDE_orig.jpg
