Expert 2875 points
Part Number: MSP432E401Y
Other Parts Discussed in Thread: MSP432E411Y, TM4C1292NCZAD, TM4C123GH6PGE

Hello:

There are some TI chips which needs to evaluated，Please help comfirm.

MCU

MSP432E401Y

Confirm whether 8 independent PWM can be supported. It is required that the PWM cycle can be inconsistent, not the duty cycle, and confirm whether PHY is integrated

    Hi,

    The MSP432E401Y and MSP432E411Y contains one PWM module, with four PWM generator blocks and a control block, for a total of eight PWM outputs. However, as your request, this PWM module can only configure with 4 different PWM cycle not 8. And there is no PHY on the PWM output. 

    The TM4C MCU belongs to another product line. Please change this thread's subject to TM4C product for more help.

    Best regards,

    Cash Hao

    Hello Cash：

    Thank you for your reply，I want to know how to change this thread's subject to TM4C product. I found that MSP432E401Y、MSP432E411Y and TM4C MCU are all belongs to Arm-based microcontrollers

    Hello Jimmy,

    I help support our TM4C device family that are part of our Arm-based microcontrollers portfolio.

    For all TM4C129x devices, there is only a single PWM module which is architected as Cash described - 1 module with 4 generators for different duty cycles.

    In addition to the PWM module, it is also possible to output PWM signals with a Timer peripheral. This has less features than the dedicated PWM module, but depending on your system requirements, perhaps this simpler output of a PWM signal would be workable. With timers you'd be able to output an additional 6 PWM on our PDT package devices or 8 PWM on ZAD package devices. So this may be an option for you to supplement the PWM module.

    We also have our TM4C123x family, these devices have some part variants (TM4C123A, TM4C123B, TM4C123F, and TM4C123G) which contain two PWM modules with 4 generators each. These would be capable of providing 8 unique duty cycles for PWM output with the full PWM peripheral. An example of such a device for you to review the specifications of it would be TM4C123GH6PGE.

    TM4C123x does not have variants with more than 256kB Flash or with an Ethernet module so if those were requirements then it would not be a fit, but I felt it would be helpful to mention these just in case their feature set could fit for this application.

    Best Regards,

    Ralph
