MSPM0L1306: Schematic Check

Nate Newman

Part Number: MSPM0L1306

Tool/software:

I intend to use the MCU to send and receive SPI signals. Hi, please see the attached schematic and let me know if the MSPM0L1306 is set correctly, as well as the 10 pin header.

Thank you,

Hello Nate,

I can only help you to review the MCU part. Your Cap between VDD and VSS is too small. You should change 4.7 uF to 10 uF. And the Cap between VOCRE and VSS is too big. You should change it to 0.47 uF. And you can refer to the design of our L1306 LaunchPad to modify your circuit.

Hi Janz,

Thank you, I've made the changes to the capacitor that you recommended. In the development kit user's guide on pg. 19, the UART connections are implemented in a different way than we've set them up. In ours, the UART is connected through an FTDI 6 pin connecter for this type of setup:

Do you have any concerns about our implementation?

Thanks,

Nate

Hello Nate,

You find that they are different because in our M0's UART, it doesn't use the hardware flow control. But I think you can do this because the CTS and RTS don't have complex logic, you can implement its code logic easily.
