Draft:TI MSPM0

  • Comment: @Caleb Stanford: sorry, you responded while I was writing my second comment; I started the Talk content to avoid that
  • Comment: Hi @Przemek Klosowsk: Please provide WP:Three sources as a comment as I requested. Also: Currently the embedded microcontrollers' market value is estimated at over US$30 billion,[2] and the low-end chips like Cortex-M take a large share of chip volume and revenue because they are widely used in consumer and industrial goods. This is not about TI MSPM0, and should be removed. Caleb Stanford (talk) 01:57, 3 September 2025 (UTC)
  • Comment: I am not sure if the article meets notability. Can you please provide the three sources in a comment which you view as the most independent, reliable, secondary, and in depth coverage on the topic? See WP:Three sources for more details. Currently, many of the articles are from TI or other primary sources.
    Regarding the article content itself (please ignore the remaining suggestions if GNG is not met). First, there is far too much jargon for a general audience article. Speaking as someone who does not work in architecture, I could not even understand the lead, much less the rest of the article. Can you please rewrite the article to provide an introduction to a general audience?
    Additionally, the references are provided as bare URLs and not formatted correctly. Please try using the 2017 WikiText editor (configurable in settings) to insert references automatically or review the syntax of a similar article with at least a B or A rating to copy that.
    If GNG is met and if the above is addressed, we can try again. Thanks! Caleb Stanford (talk) 04:17, 14 July 2025 (UTC)
  • Comment: The embedded microcontroller chips are in every consumer and industrial product now, from toothbrushes to cars, to military technology; the yearly deployment is in tens of billions. This article describes a new(-ish) product line introduced by a US-based manufacturer (TI aka Texas Instruments), which garnered interest from both professional electronic industry and hobbyists (see first few references in the article), due to TI's reputation for quality of product and documentation . I hope the intro in the article addresses that and provides reasonable references. I note that other, existing articles about other product lines from TI are well-read and respected Wikipedia articles.

MSPM0 is a family of microcontroller integrated circuits by Texas Instruments, based on the 32-bit ARM Cortex-M0+ processor core. It is TI's entry into the low-end Cortex-M embedded microcontroller category[1].

The low-end embedded microcontroller market segment is currently dominated by STMicroelectronics, NXP, Infineon, Microchip and Renesas, as well as numerous Far Eastern clones. TI has been trying to increase their share of this important market segment, attempting to extend the success of their 16-bit MSP430 line by offering similar but more capable 32-bit ARM Cortex-M products. Their original attempt, the MSP432 family, had limited success and was deprecated in 2021.[2]. TI is an important supplier to the US domestic market because of their in-shore design and manufacturing facilities.[3]

Introduction

[edit]

Like MSP430 and MSP432, MSPM0 is a general purpose embedded microcontroller. It has a rich set of internal peripheral devices and functions that is somehow compatible with widely used MSP430 chips, and is designed for low power requirements. It is simple, inexpensive, and includes very small, millimeter-sized packages.[4][5]

Families

[edit]

The MSPM0 has four family variants:[6][7]

The lowest end MSPM0C1103 bulk price is 16 US cents, and even the largest advanced models are around a dollar.[8] The MSPM0C1103/4 manual page also mentions two parts designated MSPS003F3 and MSPS003F4 that seem to be almost identical; they seem to be recommended as replacements for STMicroelectronics STM8[9]

The fourth digit of the part number (e.g. MSPM0C110n ) denotes the flash size, which can be calculated as 2n kB:

...3 ...4 ...5 ...6 ...7 ...8 ...9
8kB 16kB 32kB 64kB 128kB 256kB 512kB

The amount of RAM tends to be between 1/8 and 1/16 of the flash size for the low-end models, and 1/2 to 1/4 of flash for the high end.

Unlike MSP432 Cortex-M4F, MSPM0 CPU does not implement floating point instructions. However, the G variant has a math coprocessor (MATHACL) that processes 32- and 64-bit fixed point numbers with dynamically selectable integer/fractional configuration.

The low power modes, including the shutdown mode, can be interrupted by I/O wakeups. Typical power consumption numbers are[10]

Run Sleep Stop Standby Shutdown
85 μA/MHz 200 μA @ 4 MHz 50 μA @ 32 kHz 1.1 μA 50 nA

The CPU clock can be sourced from an internal high speed oscillator or an internal 32kHz oscillator.

The packages range from 8 pins (DSBGA, VSON, SOT) to 100 pins PQFP. The smallest DSBGA package is the size of a 0603 resistor (1.6 mm by 0.86 mm).

The power supply voltage range is 1.62 to 3.6V and the common operational temperature range is -40 °C to 125 °C An optional postfix -Q1 denotes a part with an automotive qualification.

Peripherals

[edit]

Depending on package, there are between 6 and 94 GPIOs. All GPIO are qualified as 5V-tolerant.

All parts have a 12-bit successive-approximation ADC, between 1 and 7 UARTS, and between 1 and 3 I2C and SPI peripherals. Some parts include CAN bus interface. The UARTs support LIN, IrDA, DALI, smart card, Manchester and low-power operation in STANDBY mode.

The high precision analog peripherals include zero-drift zero crossover operational amplifiers, and high-speed comparators and DACs, as well as an integrated voltage reference and temperature sensors.

The DMA controller and advanced timers help offload CPU from routine data transfer and timekeeping tasks. There is a watchdog timer peripheral as well as a dedicated simple beeper oscillator.

Hardware development platforms

[edit]

There are LaunchPad development boards for several chips in the family. [11] They have an USB interface to an on-board XDS110 SWD/JTAG development tool, connected to the respective target MCU, for downloading code and debugging, as well as the TI Energy Trace [12] real-time power and current measurement hardware.

Development tools

[edit]

Cortex-M0+ is supported by Open Source tools: GCC and LLVM, using CLI as well as VSCode, and openOCD/gdb.

TI provides proprietary MSP Zero Code Studio[13] and Code Composer Studio, as well as middleware libraries for specialized tasks such as FOC motor drivers.

The parts are supported by FreeRTOS and Zephyr realtime operating systems.
