TMS320F28377S: Guideilines for PCB layout - Vcc and GND

Alberto Generali
Intellectual 370 points

Part Number: TMS320F28377S

On the launchpad, all voltages (VDDIO, VDD, VDDOSC, VDDA) are filtered with an LC tap.

There is an application note with some suggestion on the decoupling and the suggested PCB layout?

thank you

Alberto

    Hi Alberto,

    We do not have a Application note, but if you go through Data sheet you will see the decoupling capacitor recommendation for each supply. 

    For Eg. 

    1.2-V digital logic power pins. TI recommends placing a
    decoupling capacitor near each VDD pin with a minimum
    total capacitance of approximately 20 uF. The exact
    value of the decoupling capacitance should be
    determined by your system voltage regulation solution.
