+Overview
+********
+
+MSPM0G511x 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 MCUs offer a blend of cost optimization and design flexibility for applications requiring 32KB to 128KB 
+of flash memory in small packages (down to 4 mm x 4 mm) or high pin count packages (up to 64 pins). 
+These devices include USB 2.0-FS interface, digital audio interface, cybersecurity enablers, high performance 
+integrated analog, and provide excellent low power performance across the operating temperature range.
+
+Hardware
+********
+
+The MSPM0G51xx devices provide up to 128KB embedded flash program memory with built-in error correction
+code (ECC) and up to 32KB SRAM with a hardware parity option. These MCUs also incorporate a
+memory protection unit, 12-channel DMA, and a variety of peripherals including
+
+* Analog.
+
+  * One 12-bit 4-Msps ADCs.
+
+  * Configurable internal shared voltage reference.
+
+  * One high speed comparator with built-in reference DAC.
+
+* Digital.
+
+  * Two 16-bit advanced control timers.
+
+  * Four general-purpose timers.
+
+    * Two 16-bit general-purpose timers.
+
+    * One 16-bit general-purpose timer with low-power operation in STANDBY mode.
+
+    * One 16-bit timer with deadband support and up to 8 PWM Channels.
+
+  * One basic software timer including 4 indenpendent configurable 16-bit counters.
+
+  * Two windowed-watchdog timers.
+
+  * One RTC with alarm and calendar modes.
+
+* Data Integrity and Encryption.
+
+  * One AES HW accelerator capable of CTR and CBC modes.
+
+  * One Cyclic Redundancy Check (CRC) accelerator.
+
+* Communication.
+
+  * Two configurable serial interfaces (UNICOMM) supporting UART or I2C.
+
+  * One configurable serial interface supporting UART or SPI.
+
+  * One dedicated SPI interface up to 32 Mbits/s.
+
+  * One digital audio interface (I2S) supporting controller and target mode.
+
+  * One USB2.0 interface with full-speed (12-Mbps) compliant device and host mode.
+
+Zephyr uses the ``lp_mspm0g5187`` board for building LP_MSPM0G5187

+
+Supported Features
+==================
+
+.. zephyr:board-supported-hw::
+
+Building and Flashing
+*********************
+
+Building
+========
+
+Follow the :ref:`getting_started` instructions for Zephyr application development.
+
+For example, to build the blinky application for the MSPM0G5187 LaunchPad:
+
+.. zephyr-app-commands::
+   :zephyr-app: samples/hello_world
+   :board: lp_mspm0g5187
+   :goals: build
+
+The resulting ``zephyr.bin`` binary in the build directory can be flashed onto
+MSPM0G5187 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_mspm0g5187
+   :goals: debug
