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.

Zephyr uses the lp_mspm0g3519 board for building LP_MSPM0G3519

Features

  • Onboard XDS110 debug probe
  • EnergyTrace technology available for ultra-low-power debugging
  • 3 buttons, 1 LED and 1 RGB LED for user interaction
  • Temperature sensor circuit
  • Light sensor circuit
  • External OPA2365 (default buffer mode) for ADC (up to 4 Msps) evaluation
  • Onboard 32.768-kHz and 40-MHz crystals
  • RC filter for ADC input (unpopulated by default)

Details on the MSPM0G3519 LaunchPad can be found on the TI LP_MSPM0G3519 Product Page_.

Building and Flashing

Building

Follow the :ref:getting_started instructions for Zephyr application development.

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

.. zephyr-app-commands:: :zephyr-app: samples/hello_world :board: lp_mspm0g3519 :goals: build

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.

.. code-block:: console

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

Flashing can also be done using JLINK.

.. code-block:: console

$ west flash --runner jlink

Debugging

You can debug an application in the usual way. Here is an example for the :zephyr:code-sample:hello_world application.

.. zephyr-app-commands:: :zephyr-app: samples/hello_world :board: lp_mspm0g3519 :goals: debug
