TMS320F28335 ePWM outputs channels

Other Parts Discussed in Thread: TMS320F28335, TMS320F28332

Hello,

I don's see in Data Sheet from TMS320F28335 the specifications for all 18 PWM outputs, it's only for 16 PWM outputs (TMS320F28332).

Anyone know for what are used another 2 PWM outputs???. What is the  PWM difference between TMS320F28335 and TMS320F28332???

Thx,

Dino

    Each of the 6 ECap-Units of the F28335 can be used to generate (edge-aligned) PWM signals. Together with the 12 outputs of the 6 EPwm-Units that gives you 18 PWM channels.

    The F28332 appears to have only 4 ECap-Units. For more differences see sprs439d.pdf!

    Adding to Johannes' post

    One error I just noticed - some of the product folders are indicating 6 eCAPs for 28334 and 28234.  These have 4 eCAP modules, not 6 (the data sheet has it correctly specified).
