TMS320F28377S: F28377 GND use problem？

Simba Su
Intellectual 560 points

Part Number: TMS320F28377S

Tool/software:

Use TMS320F28377S and datesheet to mark analog pin 17/35/36 and digital pin 101.

Simply using a multimeter to test this chip, analog PIN17 and PIN35 are compatible with digital PIN101, while analog PIN36 is incompatible with digital PIN101. Can I only use one analog PIN36 when using this chip? Other analog ground PIN17 and PIN35 can only be used as digital ground because they communicate with digital ground PIN101. Or is there any recommendation for digital and analog use?

    Hi Simba, 

    What pin package are you looking at? 

    This device doesnt have AGPIO option (same pin usage for Analog or digital). Once i know the package I can confirm on this?

    on the latest devices, yes we have an option where same pin can be swapped for analog or digital. both cannot be done at same time. 

    Thanks & Regards,

    Uttam
