TMS320F280037C: Pin-to-pin options and alternatives

Part Number: TMS320F280037C
Other Parts Discussed in Thread: TMS320F2800137

Hi Experts,

We are reviewing the C2000 microcontrollers for potential use in a product. 

https://www.ti.com/microcontrollers-mcus-processors/c2000-real-time-control-mcus/products.html#1228=1%3B3&sort=2955;asc&

Parts in this family of microcontrollers seem to have a part number format of TMS320F2800nnn-nn, where the nnn-nn is a combination of numbers and letters. We are wondering if two parts from the TMS320F2800 family are available in the same package, e.g., 48 pin LQFP (PT), does that mean they are a pin-to-pin compatible? As an example, if the TMS320F2800137 in the 48 pin LQFP (PT) package is initially designed into a product, is the TMS320F280037C-Q1 in the 48 pin LQFP (PT) a pin-to-pin compatible part?

In this example, the TMS320F2800137 is a non-automotive / non-safety rated component.  Should the need arise for an automotive grade / safety rated microcontroller, it would be good to know if a pin-to-pin compatible device in the same product family is available.  There are other examples of this, too.  For example, some of the parts in the TMS320F2800nnn-nn are available in the 64 pin LQFP (PM) package.

Are other TMS320F2800nnn-nn parts in the 64 pin LQFP (PM) package considered pin-to-pin compatible?

We are aware with the comparison tables and pinouts packages, but we would like to confirm it from an experts especially those options with "Configurable logic block" feature.

Thank you for your guidance.

Regards,
Archie A.

    We have made intentional signal placements across these devices, F28002x/F28003x/F280013x/F280015x to drive pin compatibility as much as possible for common packages.  I would say that in this case for the 64 pin you should be able to migrate fairly easily across these devices.

    We have also made migration guides across these devices to help with any potential pin differences, etc.

    In the above case the F280015x devices are the Q grade alternatives to the F280013x and with the exception of a single GPIO are pin/pin compatible.  This IO is replaced by the VREG enable pin on the F280015x device to support off chip core supply for flexibility desired in the automotive space.  There is a 64 pin variant of the 0013x that has this VREG enable pin as well, if that was the starting device it would be 100% pin compatible.

    The F280015x adds an additional lockstep core for safety application, in addition to increasing some peripheral counts.  The migration guide will go into this detail.

    In the case of the F28003x, this device is pin compatible to the F28002x mentioned above in the 64 pin package, so you can use this guide:

    Coming from the F28002x/3x there are 2 power pins that have become GPIOs on the 13x/15x family. 

    Best,
