MSP430™ Microcontrollers

MSP430 Microcontrollers (MCUs) from Texas Instruments (TI) are 16-bit, RISC-based, mixed-signal processors designed specifically for ultra-low-power (ULP). MSP430 MCUs have the right mix of intelligent peripherals, ease of use, low cost, and lowest power consumption for thousands of applications – including yours. TI offers robust design support for the MSP430 MCU platform along with technical documents, training, tools, and software to help designers develop products and release them to market faster.

Key Features

  • Up to 10x performance, including true 16 MIPS operation
  • Five power modes with ultra-low standby power of 0.4µA and<1µs wake-up time
  • Integrated intelligent peripherals
  • Up to 2KB flash and 128B RAM - future devices will include up to 16KB flash and 512B RAM

Leading ultra-low power consumption drives longer battery life and smaller form factors


Typical battery powered applications spend 99-99.9% of their time in standby mode. MSP430G2xx power consumption is lower than typical 8-bit MCUs - as low as (at 2.2V):

  • 0.1µA RAM retention
  • 0.4µA standby mode (VLO)
  • 0.7µA real-time clock mode
  • Ultra-Fast Wake-Up From Standby Mode in <1µs

Up to 10X lower power

Competing low cost 8-bit products require the CPU to be active for each ADC conversion and loaded data transfer. MSP430’s ADC10 with Data Transfer Controller (DTC) can manage ADC samples throughout entire memory range – All without CPU overhead!

  • Less time in Active Mode saves power
  • CPU available for other more advanced tasks
  • Intelligent autonomous
  • Deterministic behavior

MSP430 Value Line devices are integrated with intelligent peripherals including ADC10 with DTC, comparators, SPI, I2C, and 16-bit timers. Upcoming MSP430G2xx devices will additionally feature capacitive touch I/O pins and UART. These intelligent peripherals allow the MSP430G2xx to do more tasks independent of the CPU, lowering average current consumption and allowing the CPU to focus on more advanced tasks.

This is especially evident in sensing, security, and other low power applications. With the MSP430G2xx’s integrated ADC10 with DTC, samples and memory allocation can be done autonomously without CPU intervention. Compared to competing MCUs, the intelligent peripherals integrated into the MSP430G2xx enable lower power consumption, minimize CPU activity, and improve code density.
