MSP430F5419 Filtering/Bypass Caps

Other Parts Discussed in Thread: MSP430F5419

I cannot seem to locate the filtering/bypass scheme for the MSP430F5419? Do you know what document would outline what to do in the layout and schematic?

Please advise, thank you

  • Paul,

    Information regarding decoupling capacitors for the F5419 can be found in either of these documents:

    User Guide:
    www.ti.com/.../slau208o.pdf

    Datasheet:
    www.ti.com/.../msp430f5419.pdf

    A search of the term 'decoupling' will return capacitor values and the locations at where they are needed. If this is not what you need, we can continue searching!

    Regards,
    Martin
  • Between VCORE and VSS, 470nF are required (and nothing else may be connected to this pin). All VCCs and VSSs should be connected, with at least 4,7µ next to them (on one or distributed between them). additional 100nF ceramic are recommended. And for VREF/VeREF, a 100nF ceramic/10µF Tantalum combo is required. (also, AVCC could be separated from DVCC by a 10..100Ohm series resistor and a 100nF/10µF combo for better analog performance, and AVSS should be routed separately form DVCC to the supply GND point)
