Key BenefitsMSP430 Microcontrollers—TheSolution for Battery-PoweredMeasurement Lowest system power extendsbattery life Integrated analog data conversionaccelerates time to market Communications peripherals enableeasy connectivity Pricing starting at 0.99 eachThe increasing demand tointegrate features and processingcapabilities into battery poweredproducts has created a need formicrocontrollers that are bothpowerful and highly integrated,while only requiring minuteamounts of energy to operate.Using its leadership in bothmixed-signal and digital technologies, Texas Instruments (TI) hasmet this challenge. The resultis the MSP430 line of ultra-lowpower microcontrollers, whichenables system designers tosimultaneously interface to analogsignals, sensors, and digitalcomponents while maintainingunmatched ultra-low-powerperformance.The MSP430 achieves its highperformance through a revolutionary architecture that integrates apowerful 16-bit RISC CPU for fastexecution of code and a designthat makes extensive use of standby modes to minimize currentconsumption when the CPU is notactive. The MSP430 architectureincludes an array of powerful andhighly flexible peripherals that arealso optimized for ultra-low-poweroperation.A key to the MSP430 performance is its unique ultra-lowpower modes. The MSP430 is ableto switch from ultra-low-powerstandby mode, where it onlydraws 0.8 µA of current, to fullcombination of features. Forapplications such as, security systems, utility metering, portablemedical devices and handheldinstrumentation, the MSP430 lineof ultra-low-power microcontrollers offer solutions that enableproduct ideas to become reality.active mode in a maximum of6 µs. This ultra-fast start upallows the MSP430 to stay instandby mode longer, eliminatingthe unnecessary current othermicrocontrollers use in rampingto active mode. In addition, whilein active mode, the MSP430 onlyrequires 250 µA in a typical 3 Vsystem. The time the MSP430stays in active mode is minimizedby its powerful 16-bit CPU, whichensures high speed and efficientcode execution.All MSP430’s peripherals areable to run independently of theCPU. This allows them to remainactive even while in ultra-lowpower standby mode. For example, an external 32 kHz crystalcan increment a counter for areal-time clock function, whilethe part is drawing just 0.8 µA.The MSP430 can also maintain anLCD display and await externalkey switch interrupts while instandby mode. This allows theuser interface to be fully activewhile simultaneously maximizingthe battery life. The MSP430 iseven capable of accepting external interrupts while it is in RAMretention/off mode. While in offmode, the MSP430 requires amere 0.1 µA of current.When battery life, processingpower and hardware flexibilityare major design concerns, TI’sMSP430 offers an unbeatable2MSP430 16-Bit RISC CPUThe MSP430’s powerful 16-bitRISC core offers many advantages over competing 4- and 8-bitmicrocontrollers. The MSP430CPU features the ease of use ofa RISC instruction set and theflexibility of numerous 16-bitCPU registers. These and otherfeatures result in a revolutionaryarchitecture that is highlyorthogonal by design.The MSP430 has a RISCinstruction set that consists of amere 27 core instructions, and tofacilitate more intuitive programming, 24 additional emulatedinstructions are included to further simplify the code generationprocess. For example, a commoninstruction such as enable interrupts (EINT) is included in theinstruction set. The assemblerautomatically substitutes theemulated instruction with thecorrect RISC instruction (BIS #8,SR). This combination of RISCand emulated instructions minimizes code space while also simplifying programming.
All instructions can be usedwith all seven addressing modesacross the entire MSP430 architecture. There are no specialinstructions or modes required towork with RAM, peripherals, theCPU, registers or any other partof the MSP430. This featuregreatly increases the efficiency ofthe 16-bit RISC instruction setand forms the basis for theorthogonal design of the MSP430.There are 16 registers in theCPU core of the MSP430. Four ofthe registers have the dedicatedfunctions of Program Counter(PC), Status Register (SR), StackPointer (SP) and ConstantGenerator (CG). The remaining12, 16-bit registers, are completely user definable.These generalpurpose registers in the CPUallow often-used variables,pointers and other data to bedirectly accessed by the CPUwithout performing memoryfetches. The number and flexibility of the CPU registers furthercontributes to the high code efficiency of the MSP430.Simplified MSP430 CPUMDB - memory data busmemory address bus - MAB150R0/PC - Program Counter0R2/SR - Status RegV SCG1 SCG0OscOffCPUOff GIE NZCR3/CG - Constant ISC ALU Shifter16MSP430 Orthogonal ArchitectureNon-Orthogonal ArchitectureAddress Modes SourceAddressModesDestination0R1/SP - Stack PointerAddress Modes ions

The DigitalController Oscillator (DCO) canbe programmed to supply a system frequency of 1 to 8 MHz.Typically the MSP430 only needsa single external 32 kHz crystal togenerate an accurate high-speedsystem frequency. Additionaladvantages of the 32 kHz crystalinclude low cost, direct division toreal-time using a single counterand the elimination of high frequency PCB layout. The 32 kHzsignal is available both internallyand externally when low frequencyis a requirement. The MSP430parts that include the FrequencyLocked Loop (FLL) circuit, automatically regulate the systemfrequency to a multiple of thecrystal.The DCO in all MSP430 productsstarts operation in a maximum of6 µs when an interrupt or resetoccurs. This allows the processorto stay in a low-power mode muchlonger and greatly reduces the timerequired to bring the part to anactive state, saving battery power.The MSP430 has a failsafe feature that allows the processor tostart operation using the DCO evenif the crystal fails. So even if thecrystal fails or is missing, theprocessor will still begin executingcode. This feature makes it possible to design MSP430 circuits thatdo not include a crystal.Features/PerformanceMSP430 Product RoadmapROM/OTP2.5 - 5 V LCD DriverFLLTimer/PortBasic Timer8-bit T/Cx33xFLASH1.8 - 3.6 VBasic ClockTimer AComparator A (notx 11x)F14xF4xxin designF13xSamples3Q 2000x32xF4xxLCD84ADC14F11x1in designTimer AComp Ax31x1996F4xxin designSamples3Q 2000LCD130Timer AUSARTMPYLCD92FLASH LCDF4xxx11xin designTimer A1999200042001

MSP430x11x(1) ConfigurationMSP430x11x(1) ConfigurationsThe low pin-count versions of theMSP430 products, theMSP430x11x and MSP430x11x1families, offer an unmatched combination of ultra-low-power consumption, Flash memory, 16-bitRISC performance and low cost.These devices consume as little250 µA in active mode, 0.8 µA instandby mode and 0.1 µA in off(RAM-retention) mode. With 1kflash, and volume 4k ROM pricesstarting as low as 0.99, the 11x(1)devices are quickly becomingthe benchmark in this price/performance category.The 16-bit RISC core operates atup to 8 MHz, allowing most of the27 core instructions to be executedwithin a 125 ns cycle. The 11x(1)devices are fully code compatiblewith all other members of theMSP430 family.Among the peripherals integrated into the 11x and 11x1 devicesare the 16-bit Timer A with threecapture/compare registers, 14individual I/O signals, the flexibleBasic Clock system, analogComparator A with references(11x1 only), Watchdog/Timer, andJTAG interface.

A real-time clock(RTC) or battery monitor/charger,with as much as 10 years of battery life, are just two applicationswhere a MSP430 device minimizessystem cost while dramatically simplifying design and reducing development time.These applications operateprimarily in low-power mode 3(LPM3), with the device interruptDCORACLKP2.5/RoscP2.4/CA1P2.3/CA0timing coming from an external32 kHz crystal oscillator. The11x(1) device periodically wakesup to update the time or to measure and adjust the chargingconditions. The pulse-width modulation (PWM) for the chargeris automatically generated evenwhile the device is in LPM3.
