Microcontrollers (MCU)

MSP430 ultra-low-power MCUs – Getting started

<Horizontal Rule - not authored>

MSP microcontrollers

MSP low-power microcontrollers  from Texas Instruments (TI) are RISC-based, mixed-signal processors that integrate smart analog/digital peripherals including advance features such as low-power embedded RF and security such as AES encryption. MSP microcontrollers offer the ultimate solution for a wide range of low-power industrial and portable applications. We also provide all of the hardware development kits and embedded software you need to get started today! Plus, TI has many complementary components to meet your needs.

Microcontrollers for industrial automation
Above you'll see an example of how MSP microcontrollers address the needs of an industrial automation application. These concepts can also be applied to a broad range of industrial and consumer applications.


  • Lowest standby power - mostly-off applications running below 25 MHz
  • Lowest power data acquisition - ADC and internal window comparator for reduced CPU wakeup time
  • Design flexibility - broadest 16-bit portfolio, now including unified FRAM technology
  • System on chip options – integrated power management, analog front ends, LCD peripherals, and security features

Low-power + performance

  • Advanced computing - up to 48MHz and lowest active power
  • High performance sensing - 1MSPS ADC and fast processing through serial communications interfaces
  • Design headroom - up to 512 KB Flash memory and 64 KB RAM for advanced algorithms, image processing and connectivity stack support
  • Minimize discrete components – integrated power management, analog, USB interface, LCD peripherals and security features


MSP ultra-low-power microcontrollers are ideal in applications where the majority of the microcontroller life is spent in standby. The latest addition to this family is the series of MSP430FRx FRAM-based microcontrollers, which offer high write speeds and nearly infinite endurance for enhanced data-acquisition and logging from sensors as well as security capabilities and new features that include IR modulation logic and dual analog-front-end’s for rotation detection.

Low-power + performance:

MSP Low-power + performance microcontrollers from TI provide designers with enhanced performance and increased design options with more peripherals on chip while using less power than ever before. These MCUs are ideal in mostly “on” battery-powered applications needing significant compute requirements. The new MSP432™ microcontrollers in this family are 32-bit microcontrollers offering higher performance with a standardized ARM® core providing the low-power benefits of MSP microcontrollers.


The RF430 and CC430 microcontroller platforms from Texas Instruments offers the industry's lowest power, single-chip radio-frequency (RF) family for microcontroller-based applications. By making Sub-1GHz and Near-Field Communication design easy, small, performance-rich and power-efficient, these system on chip help advance RF networking applications ranging from building automation to asset tracking. Beyond integrated RF, we also offer software examples and TI Designs for creating systems with MSP microcontrollers and standalone transceivers from TI.

Technology differentiators

The lowest-power

MSP low-power 16-bit and 32-bit microcontrollers offer the lowest power-consumption in the industry and now, you can see for yourself. The Embedded Microprocessor Benchmark Consortium (EEMBC), is now offering the ULPBench™ benchmark. This new ULPBENCH benchmark accounts for system functions that include the real-time clock, power modes and integrated hardware. This benchmark provides a true comparison of system-level current and energy efficiency across microcontrollers. Scores are available today, or developers can use the ULPBench EnergyMonitor™ to compare devices themselves.

MSP low-power microcontrollers perform 30 percent better than the closest competitor due to a design focused on application-level power-consumption that includes a low-leakage manufacturing process, design/architecture techniques, and software-managed power conservation capabilities (individual peripheral and five device level low power modes (LPMs)). LPMs combine clock gating and the use of low/high frequency clocks to deliver optimal current consumption, performance, autonomous peripheral operation, and minimal power-up latencies.

Productive low-power modes allow:

  • Take ADC Samples
  • Transfer data throughout memory range
  • Output PWM signalUpdate LCD
  • Send and receive serial communication

Integrated peripherals

The 400+ MSP devices offer high-performance peripherals including USB, RF, LCD controllers and Sigma-Delta ADCs. This allows designers to find the appropriate MSP device for many low power applications. This integration enables solutions with smaller physical footprints and reduced bill of materials costs.

Our peripherals have been designed to give you maximum functionality and provide system-level interrupts, resets and bus arbitration at the lowest power. Many peripherals may function autonomously, thereby minimizing CPU time spent in active mode. This means that MSP microcontrollers offer more performance with less power.

New on MSP432™ microcontrollers - To achieve the highest performance while maintaining low power operation, the new MSP432 microcontrollers family includes additional integrated peripherals and features including a 1MSPS 14-bit ADC, integrated LDO and DC/DC converters, independent flash banks, selectable RAM retention, Driver Libraries in ROM and 1.62 – 3.7V IO.
