TMS320F28P650SH: is ADCB channel 20 available on 100-pin package?

Part Number: TMS320F28P650SH
Other Parts Discussed in Thread: SYSCONFIG, C2000WARE

Tool/software:

Hi Champs,

The Pin attributes table in the datasheet shows muxed funtions on pin #23 which includes ADCB input 20. However, SysConfig says that the B20 not available for 100-pin package.

Please confirm.

Regards,

Kien Nguyen

    Hi Kien,

    Thanks for bringing this to our notice. Datasheet is correct there seems to be some issue with Sysconfig tool. 

    Can you let us know the C2000WARE & SYSCONFIG tool versions .

    Hi Nilesh,

    Thanks for your reply.

    My customer used desktop version of CCS and C2000WARE, not sure which versions but likely the latest ones. I used the cloud-based SysConfig to check and confirm.

    If you look at the pinout diagram (p22 of the datasheet), you will see that pin #23 only supports A2, not B20. Pins that support more than 1 ADC inputs will show both, for example the pin #26 showing A14/B14/C14. It's aligned with the SysConfig.

    This may cause a device change at my customer side. So could you please double check with the team and let me know at your soonest?

    Regards,

    Kien Nguyen

    Hi Kien

    I have checked this is a Sysconfig issue which i am taking up with the team. 

    The table in the TRM is correct A2 & B20 are on the same pin. Have checked other pins as well the muxing metioned as per the table is correct.

    Only for pin 26 & pin 27 all ADC muxing options are present & has same ADC channel, that would be one of the reason for mentioning all muxing combinations .

    BR,

    Hi Kien,

    Team is looking into it. Once they completely check this it should be fixed for the next role out for sysconfig / C2000 ware versions.

    For now you can try supressing the error in Sysconfig tool and try if that works.

    BR,
