Tiva TM4C123x

Good day!

Team i am looking for a MPU that is able to support the requirements menitioned bellow. I believe that the TM4C123GH6PGE, will operate under those requirements, but i want to have your opinion, and if you have a better suggestion will be greatly appreciat it. 

  • ADC - 6 state variables sampled every 10us, (600KSPS 10-bit)
  • PWM - 4 independent PWM channels that can be phased relative to one another, i.e. 90 degrees apart.
  • Core - enough processing overhead to enable updating three second order loop filters and checking for fault conditions every 10us, > 64MHz instruction clk requested.

Best,

Antony Carvajales

    Hello Antony,

    I have the following clarifications on the requirement and comments

    CLARIFICATION-ADC: Do you mean 6 channels sample every 10us with 600KSPS and 10-bit resolution?

    COMMENT-ADC: TM4C123 ADC can do 6 channels with a timer triggering sample conversion every 10us at 1MSPS and 12-bit resolution of 500KSPS with 12-bit resolution. You can truncate the 2 LSB's

    COMMENT-PWM: PWM channels can be phased in pairs. Global Synchronization can be used to do more than 2 channels

    CLARIFICATION-CORE: Do you mean 64MHz Clock per instruction?

    Regards
