MSP430F147IPM 概要
A microcontroller (MCU) is a single-chip computer that integrates a CPU, memory, and programmable peripherals. Within the semiconductor taxonomy, the MSP430 belongs to the 16-bit ultra-low-power MCU family, sitting below 32-bit ARM Cortex-M devices and above 8-bit 8051-class controllers in performance and addressable memory. Texas Instruments' MSP430 platform is specifically optimized for battery-powered and energy-harvesting applications, where standby current dominates total energy consumption.
Key features include five low-power operating modes with sub-6 us wake-up from standby, a 16-bit RISC architecture with 27 instructions and constant generators that maximize code density, a 12-bit 200 ksps analog-to-digital converter with internal reference, a 16-bit hardware multiplier for efficient DSP-like math, and 22 programmable I/O pins with edge-selectable interrupts. The integrated Analog Comparator and two USARTs reduce external component count, enabling single-chip mixed-signal designs.
The MSP430F147 employs a von-Neumann unified memory map with a 16-bit data bus and 16-bit registers, yielding efficient C and assembly code density. The 12-bit SAR ADC includes sample-and-hold plus an internal 1.5 V or 2.5 V reference, suitable for sensor linearization. Hardware-multiplier execution reaches 8 MIPS at the 8 MHz top MCLK, while RAM-retention current is below 0.1 uA - critical for sealed-battery applications.
Typical applications include portable medical instrumentation (glucometers, blood-pressure cuffs), industrial sensor transmitters, smart thermostats and HVAC nodes, battery-powered metering, and remote controls. The combination of 32 KB Flash and 1 KB SRAM is well matched to mid-density control loops with modest data logging.
When designing with this device, select the LQFP-64 footprint carefully against the larger LQFP-80 used by MSP430F149/F1491 - the pin maps differ. For systems requiring CAN, USB, or hardware AES, choose an MSP430F5xx/F6xx part instead, because the F1xx family does not integrate those peripherals.

主な用途
MSP430F147IPM の用途: 6 件s: Portable Medical Instrumentation, Industrial Sensor Transmitters, Smart Thermostats and HVAC Nodes, Battery-Powered Metering (Gas/Water/Electric), Remote Controls and Consumer RF, Data Loggers and Environmental Monitors.
Portable Medical Instrumentation
The MSP430F147IPM's 0.1 uA off-mode (RAM-retention) current and sub-6 us wake-up from standby make it an ideal host for battery-powered medical devices such as glucometers, blood-pressure cuffs, and pulse oximeters. The 12-bit SAR ADC with internal 1.5 V or 2.5 V reference digitizes sensor signals directly without an external ADC, while 32 KB Flash accommodates mid-density firmware for measurement averaging and BLE/HID interface stacks. Power dissipation at 2.2 V with 1 MHz MCLK stays below 200 uA, extending coin-cell life to 1-3 years depending on duty cycle.
おすすめ
Industrial Sensor Transmitters
The MSP430F147IPM's integrated 12-bit ADC plus analog comparator and 1.8 V to 3.6 V supply tolerance suit 4-20 mA loop-powered or 24 V-bus powered sensor transmitters. The 22 programmable I/O pins handle HART modem interrupts, RTD or thermocouple conditioning switches, and 4-20 mA current-loop drivers. Five low-power modes (LPM0 to LPM4) plus sub-6 us wake-up let the MCU spend 99 percent of time in standby while still meeting IEC 61000-4 EMC targets, and the LQFP-64 footprint simplifies thermal management at -40 to +85 C industrial temperatures.
おすすめ
Smart Thermostats and HVAC Nodes
Battery-powered or energy-harvesting thermostats leverage the MSP430F147IPM's <1 uA standby and 0.1 uA off-mode currents to achieve 5-10 year life on two AA cells. The 12-bit ADC digitizes NTC thermistor bridges with 0.1 C resolution, and the two USARTs interface Zigbee or Sub-GHz RF modules such as CC1101 for wireless control. The 16-bit hardware multiplier accelerates proportional-integral HVAC control loops without consuming extra MIPS, while the integrated analog comparator enables zero-crossing detection on 24 VAC furnace signals.
おすすめ
Battery-Powered Metering (Gas/Water/Electric)
Utility metering designs exploit the MSP430F147IPM's 0.1 uA RAM-retention current for 10-15 year battery life on sealed lithium thionyl chloride cells. The 12-bit ADC captures pulse outputs from reed-switch flow sensors or current-shunt electricity meters with 0.025 percent FS resolution, while 1 KB SRAM accumulates 30-day rolling consumption logs. The two USARTs support optical/IEC 62056-21 readout ports and wireless M-Bus modules at 868 MHz, and the wide 1.8 V to 3.6 V supply tolerates battery droop without brownout resets.
おすすめ
Remote Controls and Consumer RF
Universal remote controls and consumer RF key fobs benefit from the MSP430F147IPM's 200 uA active current at 1 MHz and the 16-bit hardware multiplier for IR protocol encoding (RC5, NEC, SIRC). The 22 GPIO pins drive 4x4 or 5x5 key-scan matrices plus RGB LED feedback without external logic, and the two USARTs stream to Sub-GHz or 2.4 GHz transceivers. Five low-power modes plus sub-6 us wake-up yield 1-2 year battery life on a CR2032 coin cell at 30 key-presses per day.
おすすめ
Data Loggers and Environmental Monitors
Environmental data loggers for cold-chain transport, weather stations, and structural-health monitoring rely on the MSP430F147IPM's deep-sleep currents below 1 uA and 32 KB Flash for storing 30 days of timestamped 12-bit ADC samples. The internal 1.5 V or 2.5 V ADC reference removes the need for an external reference IC, reducing cost, and the integrated comparator triggers wake-up on threshold crossings without CPU intervention. SD-card or serial-Flash data offload uses one USART in SPI mode at up to 4 MHz.

設計ノート
Estimated: at VIN = 3.3 V, MCLK = 8 MHz active, the MSP430F147IPM draws approximately 1.6 mA (around 200 uA per MHz). For battery life calculations, use LPM3 standby at 1 uA for periodic wake duty cycles. Place a 0.1 uF decoupling capacitor on each DVCC/AVCC pair as close to the pin as possible, plus a single 10 uF bulk cap on the DVCC rail. Do not exceed 3.6 V on any supply pin or the Flash may be corrupted during write cycles.
Route XIN and XOUT traces short and symmetric, with the load capacitors (typically 12-22 pF) placed within 5 mm of the IC. Keep digital switching signals away from AVCC and VREF traces to avoid ADC noise coupling - guard the analog ground AVSS with a continuous pour back to the supply. The LQFP-64 has a thermal pad variant on some F14x derivatives, but the F147 IPM package has no exposed pad, so no center thermal pad connection is needed.
Do not confuse the MSP430F147IPM (LQFP-64) with the F149IPAG (TQFP-64, 12x12 mm) - the pin maps differ on several VREF and port pins. Always verify pinout against the datasheet, not a generic MSP430 pinout diagram. The RST/NMI pin must have a 47 kohm pull-up to DVCC; leaving it floating may cause spurious resets. JTAG fuse blowout for code security is irreversible - ensure firmware is fully validated before blowing.
