5 Renesas RX23E-B controllers

What the title says . Good analogue front end, low noise, many bits ADC. None of that ARM rubish :)

    This is the scope that I've set for the PCB I'm designing. Based on Renesas' starter kit: green: part of my board blue: I offload to separate plug-in PCBs red: I don't use, and make the relevant…

    part 1 done. All primary pins assigned Digital and infra (clock, debug, reset, ...) left, analogue right. Power and ground top and bottom. Digital left, analogue right.

    Sorry! Why do we need to blame ARM for ADC ?!!

    "none of this XXX rubbish" is a standing expression on EEVBlog. Where XXX could be anything that you usually have, but this particular thing does not have.

    There is a smiley after it.

    I'm creating the microcontroller symbol

    image

    100 pins, most of them with 2 - 3 - 4. It 'll be a while ...

    Part 2 started: define alternative pin functions:

    this is a big job.

    To make an active low function show with a line above the label, enclose it in ~{}

    image

    For an appreciation of the scale of the exercise: most pins have a lot of functions:

    It's a lot of work to do - I usually (using a CAD system that doesn't support multi functions for pins) do new footprints for a significant new job so I can break the part up into functional blocks that make sense for the design.

    Once you have defined the Renesaspart with its multi function pins I'll be interested to see how you choose the function in the design -  and how easily you can move them about.

    Here's a thought - now that Renesas has bought Altium I suppose that its very unlikely that they would put much effort into doing Kicad symbols for their products.

    Which is a shame (if true).
