AM2634: Standard vs. Enhanced Analog Pinout

Steven
Prodigy 30 points
Part Number: AM2634

Hello TI Experts,

I am trying to understand the differences between the "Enhanced Analog", and the "Standard Analog" listed in "Table 10-1. Nomenclature Description" of the TI AM2634 Datasheet, and expanded upon in "Table 5-1. Device Comparison" as it relates to pin multiplexing and availability on different device variants.

I am unable to find documentation describing:

1. Which parts of the analog subsystem are present in the Standard version? Example 16x EHRPWM vs 32x EHRPWM, is it EPWM0 to EPWM15 that are included on the Standard? Or some other mix.

2. Do pins that no longer have analog functionality present in the Standard version compared to the Enhanced still maintain all other multiplexable functionality?

Thanks

    It will always be the lowest peripheral number (EPWM0 for example) up to the maximum count provided for that device with no breaks in between.

    The multiplexing functionality available is also dependent on these:

    (6) Programmable Real-Time Unit Subsystem is available when selecting an orderable part number that includes a feature code of D, E, F, K, L, or M. Refer to the Nomenclature Description table for definition of feature codes.

    (7) Industrial Communication Subsystem Support is available when selecting an orderable part number that includes a feature code of D, E, F, K, L, or M. Refer to the Nomenclature Description table for definition of feature codes.

    When accounting for that as well, then yes all other functions would be available.

    Best Regards,
