MSPM0G3519 Launchpad

Overview

MSPM0Gx51x microcontrollers (MCUs) are part of the MSP highly integrated, ultra-low-power 32-bit MCU family based on the enhanced Arm® Cortex®-M0+ 32-bit core platform operating at up to 80-MHz frequency. These cost-optimized MCUs offer high-performance analog peripheral integration, support extended temperature ranges from -40°C to 125°C, and operate with supply voltages ranging from 1.62 V to 3.6 V.

Hardware

The MSPM0Gx51x devices provide up to 512KB embedded flash program memory with built-in error correction code (ECC) and up to 128KB SRAM with a hardware parity option. These MCUs also incorporate a memory protection unit, 7-channel DMA, math accelerator, and a variety of peripherals including

Analog.
- Two 12-bit 4-Msps ADCs.
- Configurable internal shared voltage reference.
- One 12-bit 1-Msps DAC.
- Three high speed comparators with built-in reference DACs.
- Two zero-drift zero-crossover op-amps with programmable gain.
Digital.
- Two 16-bit advanced control timers.
- Nine general-purpose timers.
  - Two 16-bit general-purpose timers for QEI interface.
  - Four 16-bit general-purpose timers with low-power operation in STANDBY mode.
  - One 32-bit high resolution general-purpose timer.
  - Two 16-bit timers with deadband support and up to 12 PWM Channels.
- Two windowed-watchdog timers.
- One RTC with alarm and calendar modes.
Data Integrity and Encryption.
- One AES HW accelerator capable of CTR, CBC, and ECB modes.
- One Cyclic Redundancy Check (CRC) accelerator.
- One True Random Number Generator (TRNG).
Communication.
- Seven UARTs, two with support for advanced modes such as LIN and Manchester.
- Three I2C supporting SMBUS/PMBUS and speeds up to FM+ (1Mbits/s).
- Three SPI, one with max speed 32Mbits/s.
- Two CAN interface supporting CAN 2.0 A or B and CAN-FD.

Building and Flashing

Building

Follow the Getting Started Guide instructions for Zephyr application development.

For example, to build the blinky application for the MSPM0G3519 LaunchPad:

# From the root of the zephyr repository
west build -b lp_mspm0g3519 samples/hello_world

The resulting zephyr.bin binary in the build directory can be flashed onto MSPM0G3519 LaunchPad using the steps mentioned below.

Flashing

OpenOCD can be used to program the flash memory on the devices.

$ west flash --openocd <path to cloned dir>/src/openocd --openocd-search <path to cloned dir>/tcl

Flashing can also be done using JLINK.

$ west flash --runner jlink

Debugging

You can debug an application in the usual way. Here is an example for the Hello World application.

# From the root of the zephyr repository
west build -b lp_mspm0g3519 samples/hello_world
west debug
