Part Number: MSPM0L1306

Tool/software:

Hi MSPM0L1306 Champ !

A customer would like to use ADC feature of MSPM0L1306 along with AM62x.

Can you please answer toward questiosn below?

1. Please tell me which of the 16 pins of MSPM0L1306 are required to be connected and which are not.
2. they ask if the peripheral circuitry (power capacitor capacity, etc.) can be used according to (MCU099_LP-MSPM0L1306 with PCB.pdf).
3. if they want to connect a debugger, can they just connect SWDIO, SWCLK two wires with AM62 MCU or do they need other wires?

They attached the spreadsheet regarding above question. Please check the attachment. then fill the your comments about interface with AM62x.

Thanks.

Best Regards,

    Hi Jack,

    1,2. The minimum system schematic could refer to MSPM0L1306 datasheet 9.1.1:

    • VCORE has to connect to gnd by 0.47uF capacity
    • ROSC could be used to correct clock frequency by collect a high accuracy 100-kR resistor to gnd
    • VREF+ is optional according the customer requirement to external reference
    • Check whether 4 ADC channels are enough for customer

    3. SWDIO, SWCLK, GND are necessary pins to be connected debugger (XDS110 or J-link)

    Hi Pengfei

    Thanks for your quick response. 

    Can you also please let us know SWDIO, SWCLK, GND coneection for XDS110?

    It's confused when we check the XDS110 user guide. 

    https://www.ti.com/lit/ug/sprui94/sprui94.pdf?ts=1727046518593&ref_url=https%253A%252F%252Fwww.google.com%252F

    We prepared the initial connection btw MSPM0 JTAG connector and XDS110. 

    Can you please double check especiially for SWDIO, SWCLK, GND?

    Thanks.

    Regards, 

    Jack

    Hi Jack,

    It seems that your XDS110 user guide version is not as the same as my side.

    Actually you could just refer the text label in your XDS110 hardware. It shows each pin name of the interface. And you just need to connect SWDIO, SWCLK and GND to MSPM0. 

    By the way, though XDS100 support both SWD and JTAG, MSPM0 devices only support SWD for debugging. So you only need to focus on SWD pins or function of XDS110.
