microcontroller and dsp at 1.5Ghz

Genius 9880 points


Hi Team,

Good day, we received query from customer looking for microcontroller that meet their requirements. For me to not miss any information, ill copy the query below.

"I am looking for microcontroller and digital signal processor recommendations

Basically, I'm on a project that is using MOSFET technologies for a transformer control system. I need to build a system that can transform a high voltage, low current power, to high current, low voltage and vice versa. I need a digital signal processor with a clock of at least 1Ghz, but preferably 1.5Ghz

Part of the reasoning behind the clock speed is that I need to be able to modify the output pwm with a granularity of 1 micro seconds. It doesn't have to "react" that fast and run the algorithms in that time, but I am trying to prioritize accuracy of the signal output. The output may be a variable voltage pwm that slices the input sine wave to produce it. A major safety concern is if the current rises too quickly, creating an over current situation, where the control system needs to shut down operations

Also, a chip that ships with a development board is a must

"

Thank you and looking forward for your kind response.

Regards,

Maynard

    Hi Maynard,

    Based on what the customer is saying, it doesn't sound like they need a 1-1.5GHz device.  What they need is a device that has capability to output a PWM with high granularity (<1us).

    The C2000 product line has HRPWM (high-resolution PWM) peripheral on it.  These can give output on the order of 150ps resolution, which should meet your need.

    Our devices also have many features to 'trip' a PWM in case of a fault condition (analog comparators & TZ trip features).


    Is there a specific power conversion topology that the customer is looking to evaluate?  We have reference designs for LLC, PSFB and others.


    Based on what I'm understanding thus far, I might recommend the F28004x series (and perhaps the F28002x series).  Both have LaunchPads or controlCARDs to assist evaluation.

    Hopefully this helps!


    Thank you,
    Brett
