MSPM0G3506: The technology support for MSPM0G3506

Part Number: MSPM0G3506


Tool/software:

Hi,

We use the MSPM0G3506 in our new project and now we have below issue:

1. We run the program in the RAM when the power on, the power consumption is reduction or not?

2. The MCU has the unique ID or not, if yes, how to get the unique ID?

3. How long of the MSPM0G3506 clock stable from 32KHz to 12MHz?

    Hi thanks for the questions. Can you clarify your first question, I don't understand what you are asking here. For the second question, yes the device has a unique 96-bit identity. You can find more on accessing this in the TRM (section 1.7: Factory Constants). For your 3rd question, I don't understand this, are you asking how long it takes to stabilize the CLK when shifting the CLK frequency from 32kHz to 12MHz?

    Hi Brian,

    We have solved the above issue and now we use the Keil IDE for the dubug, and now, we have below issue that need your help:

    1. We need the MCU work in the 32.768KHz clock and then we need to MCU is re-work when the MCU get the IO signal, if the MCU support this request?

    2. When the MCU run on the 32.768KHz clock, we need the the below:

    1) Can a low-speed UART (such as 1200bps) transmit and receive normally?


    2) Can the timer count this 32K? Can the program retrieve the timing interval based on a multiple of 30.5 μ s through a query?


    3) Can I enter Keil simulation debugging, single step tracking, etc. under SWD or JTag?

    3. For the hardware, we have much more MCU is damaged, during the communication process, the communication pulse is coupled by a capacitor,

    and the maximum pulse amplitude is around 12V. It is then connected to the comparator input through a 220K+390K resistor,

    and the other end of the 220K resistor is clamped to 3.3+0.7V by a diode to the power supply. In theory,

    such a large resistance value should not cause damage to the I/O port, is it right?

    4. Can you help to check our schematic diagram that how to protect our MCU to avoid damage? thanks.
