Minimum system board based on MSPM0G3507 (LQFP64 package)

I. Team Introduction:
Based on the "MSPM0 MCU System Board Design Scheme Solicitation" activity, this project was developed independently by Mr. Liu.
II. Project Requirements
III. Design Summary:
Power supply, download, testing, LED, button, serial port, etc.
IV. Project Analysis:
Considering the corresponding debugging requirements, all pins are brought out. A dedicated download interface is provided, and it can also communicate directly with TYPE-C and CH340N serial ports. Corresponding LEDs and user buttons are integrated. After inputting 5V, an AMS-1117 regulated power supply solution is used to provide 3V3. The input port is protected by a 0.5A self-resetting fuse.
V. Overall Design Block Diagram:
Typical application circuit of AMS1117-3V3
. Refer to the MSPM0 hardware manual; the officially recommended typical circuit can be found by scrolling down.
To match the TI board program, LED test lights and user buttons with the same ports were designed.
VI. Hardware Circuit Composition
VII. Program Flowchart:
Compatible with some TI sample code, therefore not specifically mentioned here.
8. Physical demonstration of
LED lighting test and
serial port test (although the serial port assistant uses STC's).
9. Precautions:
Some 0-ohm resistors can be shorted as needed. Choose one set of R9/R12 and R11/R14 for soldering (Important!!!).
