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.

Architecture
A 16-bit RISC CPU, peripherals and flexible clock system are combined by using a von-Neumann 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’s and tomorrow’s mixed-signal applications.

Product Portfolio
MSP430 offers both non-LCD (x2xx and F5xx) and LCD-based (x4xx) product families.
- MSP430x1xx
The MSP430x1xx are Flash/ ROM based MCUs offer 1.8V to 3.6V operation, up to 60kB, 8MIPs with Basic Clock. This family of MCUs offers a wide range of capabilities from a simple low power controller with a comparator, to complete systems on a chip including high-performance data converters, interfaces and multiplier.
- MSP430F2xx
The new ultra-low-power MSP430F2xx family increases performance up to 16 MHz. Additional enhancements of MSP430F2xx, include an integrated ±1% on-chip very lowpower oscillator, software-selectable, internal pullup/pull-down resistors and increased number of analog inputs. The in-system programmable Flash has also been improved with smaller 64-byte segments and a lower 2.2-V programming voltage allowing the elimination of external EEPROMs in most systems.
Available in low-pin count options.
- MSP430x4xx
The ultra-low-power MSP430x4xx devices offer 1.8V-3.6V operation, up to 120kB/ Flash/ ROM 8MIPS with FLL + SVS along with an integrated LCD controller for low power metering and medical applications. Several devices offer application-based peripherals to provide single-chip solutions for flow and electricity metering.
- MSP430x5xx
New Flash-based family featuring the lowest power consumption up to 25 MIPS with 1.8 to 3.6V operation starting at 12 MIPS. Features include an innovative Power Management Module for optimizing power consumption, an internally controlled voltage regulator, and 2x more memory than previous devices.

- eZ430 Development Tools
Designing with the world’s lowest powered MCU just got even easier with the new eZ430-F2013 complete development tool for only $20! The platform provides all needed hardware and software in a portable USB stick enclosure. The eZ430 family of tools include the IAR Kickstart IDE as well as TI’s own Code Composer Essentials IDE, providing full emulation with the option of designing a stand alone system or detaching the removable MSP430 target board to integrate into an existing design. The eZ430 family of tools has everything from the smallest eZ430 available to MSP430s with several integrated Op-amps and ADCs as well as wireless transceivers and Zigbee radios for under $100! TI recommends that you start your search for microcontrollers by ordering one of these tools today. From here you can move up to one of our larger development kits.
- MSP430 Development Kits and Flash Emulation Tools
The Flash Emulation Tool (FET) supports complete in-system development and is available for all Flash devices. Programming, assembler/C-source level debug, single stepping, multiple hardware breakpoints, full-speed operation and peripheral access are all fully supported in-system using JTAG.
The FET kit comes with a programming interface, a target board and a free version of an integrated development environment – everything you need to complete an entire project.
- Integrated Development Environments
Texas Instruments and third party developers offer Integrated Development Environments (IDE) to program all MSP430 devices. Full C-compilers are available for purchase enabling customers to develop and debug code in seconds. Free, code limited versions are also available.
Download free 4KB IAR Embedded Workbench Kickstart and the 16KB limited Code Composer Essentials tools.
