TMS320F28027: Some issues about the chip

Cherry Zhou

Part Number: TMS320F28027
Other Parts Discussed in Thread: TMS320F280049, SFRA, , CONTROLSUITE

Hi team,

Here're some issues from the customer may need your help:

Reference for the inverting power UPS is tidm_hv_1ph_dcac, and the original scheme chip is TMS320F280049. Questions are as below:

1)Are there any example of using SFRA for TMS320F28027?

2) Are there any examples of TMS320F28027 using the DCL_ library?

3) Are there any examples of TMS320F28027 using the PRcontroller?

4) What is the principle for the value "sfra1.freqVect[" array in the original scheme void setupSFRA(void)?

Could you help check this case? Thanks.

Best Regards,

Cherry

1. Cherry, F28027 is pic-A device, I am not aware of examples using SFRA with Pic-A, we do have examples with PIc-B i.e. F28035 device which is still fixed point processor in controlSUITE.

2. None that i am aware off

3. PR controller with fixed point processor may be problematic, we do not have any examples

4. it points to the number of point SFRA needs be analyzed.

I will highly recommend customer look at F28002x devices.

Hello Manish,

Thanks for your help.

They would like to know if the F28002x is compatible with the TMS320F28027.

Thanks and regards,

Cherry,

I am not sure what definition of compatibility is, but if they are using hv-1ph-dcac as a starting point it is much easier to port that to F28002x than to F28027.

Could you help provide an example of the F28035 using SFRA below? Also, does the F28002x have pin 48?

Thanks and regards,
