The World’s Lowest Power Microcontrollers
MSP430™ Microcontroller DNA
Highly Integrated
MSP430 MCUs are highly integrated and offer a wide range of high-
performance analog and digital peripherals.
Easy to Get Started
MSP430 MCUs are easy-to-use because of a modern 16-bit RISC
architecture and a simple development ecosystem.
Intelligent Peripherals
16-Bit Orthogonal Architecture
The MSP430 MCUs peripherals have been designed to assure maximum
functionalityandprovidesystem-levelinterrupts,resetsandbusarbitration
at the lowest power. Many peripherals may function autonomously,
thereby minimizing CPU time spent in active mode.
The MSP430 MCU’s 16-bit architecture provides the flexibility of 16
fully-addressable, single-cycle, 16-bit CPU registers with the power of a
RISC. The modern design of the CPU offers versatility using only 27
easy-to-understand instructions and seven consistent addressing modes.
High-Performance Integration

Clock
The 400+ MSP430 devices offer high-performance integration including
USB, RF, LCD controllers and Sigma-Delta ADCs. The scalable portfolio
allows designers to find the appropriate MSP430 device for many low-
power applications. The MSP430 MCU’s high integration also enables
solutions with smaller physical footprints and minimizes the overall bill
of materials.
