What is the MSP430?

The MSP430 family of ultra-low-power 16-bit RISC mixed-signal processors from Texas Instruments (TI) provides the ultimate solution for battery-powered measurement applications. Using leadership in both mixed-signal and digital technologies, TI has created the MSP430 which enables system designers to simultaneously interface to analog signals, sensors and digital components while maintaining unmatched low power.

Typical applications include utility metering, portable instrumentation, intelligent sensing, and consumer electronics.

MSP430 Key Features and Portfolio

Meet the world’s lowest power microcontrollers family. MSP430 offers 200+ ultra-low power microcontrollers devices. Each device features a flexible clocking system that enables up to 7 Low Power Modes (LPMs), which allow increased optimization. when paired with our instant, sub-1us wakeup time and various interrupt sources, MSP430 ensures that your application only uses the appropriate clocks and peripherals that are needed to perform the task at hand.

Key Ultra-Low Power metrics:

  • Various Low Power Operating Modes
    • Ultra-Low Power Active Mode: Down to 120 µA/MHz @ 2.2V
    • Standby Mode w/self wakeup & RAM retention (LPM3): Down to 0.7µA @ 2.2V
    • Standby Mode w/self wakeup (LPM4): Down to sub-100nA @ 2.2V
    • Shutdown Mode w/RAM retention (LPM3.5): Down to sub-100nA @ 2.2V
  • Instant sub-1us wakeup time from Low Power Modes
  • Always-on zero power brown-out rest

High Performance 16-bit Architecture. A 16-bit RISC CPU, peripherals and flexible clock system are combined by using a von-Neuman common memory address bus (MAB) and memory data bus (MDB). Partnering a modern CPU with modular memory-mapped analog and digital peripherals, the MSP430 offers solutions for today and tomorrow's mixed-signal applications.
