TMS320F28377D MEP step

Other Parts Discussed in Thread: TMS320F28377D

Hi All,

I'm searching for the specification of HiRes PWM on a TMS320F28377D. What is the MEP stepsize on this controller at 200MHz?

Thank you in advance.

Best regards,

Tjarco

    Tjarco,

    We expect this to be very similar to  the 150 nom / 310 ps max as seen on Concerto.  Please look for the official numbers in a future datasheet release.  Thanks,

    Hi Kris,

    Thank you for your reply. What I don't quite understand is that a C2000 with a high core frequency c.q. 200MHz could have the same or worse MEP step than a C2000 running on 150MHZ (F28335) or 100MHz (F2808).

    In this thread someone has a 150MHz Delfino core resulting in a MEP step of 130ps. I would expect a smaller MEP step at 200MHz, right? When are the official numbers expected to be released?

    Best regards,

    Tjarco

    Tjarco,

    The MEP step size is not related to the system clock frequency but the technology the device is based on.  I do not have a date for when the official numbers will be released at this time.  You should be safe expecting the 150/310 though.

    Hi Kris,


    Oke thanks. So it's just some fixed delay line logic (taps) you choose.

    Is there a target for the release of official specs? Like, "summer" or "winter" or somewhere 2nd quarter of 2016?

    Best regards
