MSP430F423IPM - 8MHz 16-Bit MCU with 3 ADCs | Texas Instruments
部品番号: MSP430F423IPM ✓ 生産中MSP430F423IPM 概要
A mixed-signal microcontroller is an embedded-control IC that combines a digital processor with analog or specialized sensing peripherals. In the broader electronics hierarchy, MSP430F423IPM belongs to the microcontroller class, then embedded processors, then semiconductor devices. Its integrated ADC channels reduce external signal-chain requirements, while the LCD interface supports compact instrumentation, metering, portable measurement, and industrial control panels.
Key features include an 8 MHz maximum clock, three 16-bit sigma-delta ADCs, 8 KB Flash, 256 B RAM, 48 I/O ports, and a 2.7 V to 3.6 V supply range. The device also provides five power-saving modes, standby wake-up in less than 6 microseconds according to the verified distributor data, and a frequency-locked loop. These features support designs that need deterministic embedded control while limiting energy use during inactive periods.
The MSP430 CPU16 uses a 16-bit RISC architecture with a stated 125 ns instruction-cycle time. Its mixed-signal peripherals are intended for sensors and low-bandwidth analog measurements where a sigma-delta ADC is appropriate. The integrated 128-segment LCD support is especially useful for meter, sensor, and handheld-instrument designs that need local numeric or graphical feedback without a separate display controller.
Typical applications include low-power sensor nodes, industrial panel meters, portable measurement equipment, environmental monitoring, battery-powered instruments, and LCD-based control interfaces. The 48 I/O ports provide flexibility for external sensors, switches, indicators, communication interfaces, and actuators. The 2.7 V to 3.6 V operating supply range aligns the MCU with common 3.3 V embedded systems, while the 8 MHz clock supports control-loop and measurement-management tasks.
For PCB design, preserve the package pin assignments and follow the manufacturer datasheet for decoupling, analog routing, LCD drive connections, and exposed or unused-pin treatment. Treat ADC signal conditioning, reference stability, and low-power transition sequencing as important validation points. Because the verified data does not provide a complete pin-level table, do not infer pin names from package position alone.
This page combines the verified manufacturer product data, distributor specifications, lifecycle information, and practical application guidance. It also distinguishes verified facts from missing parameters and avoids presenting unverified electrical, pricing, or pinout values as datasheet specifications.

主な用途
MSP430F423IPM の用途: 6 件s: Low-Power Sensor Instrumentation, Industrial Panel Meters, Environmental Monitoring, Portable Measurement Equipment, Battery-Powered Metering, LCD-Based Control Interface.
Low-Power Sensor Instrumentation
MSP430F423IPM fits low-power sensor instrumentation because it combines three 16-bit sigma-delta ADCs with a 16-bit RISC CPU and five power-saving modes. The 2.7 V to 3.6 V supply range fits common 3.3 V systems, while standby wake-up in less than 6 microseconds supports duty-cycled measurement. A typical design uses the MCU to acquire sensor channels, process the readings, and update a local display only when needed. The 8 MHz clock provides control and data-management capability without relying on a separate processor. Because the verified data does not specify input impedance, reference voltage, or ADC acquisition timing, those values must be taken from the current manufacturer datasheet before final analog design.
おすすめ
Industrial Panel Meters
MSP430F423IPM is well suited to compact industrial panel meters because it provides a 128-segment LCD interface, 48 I/O ports, three 16-bit sigma-delta ADCs, and a 2.7 V to 3.6 V supply range. The MCU can acquire process-voltage or sensor information, perform scaling and filtering in firmware, and drive the meter display without requiring a separate LCD controller. Five power-saving modes can reduce activity when the instrument is not being read continuously. The 64-LQFP package provides a defined surface-mount footprint, while the industrial operating-range designation supports industrial-oriented designs. Actual LCD glass compatibility, segment drive voltage, and electrical limits must be checked in the exact datasheet and display documentation.
おすすめ
Environmental Monitoring
MSP430F423IPM can serve as the controller in an environmental-monitoring node that periodically reads sensors and presents local information on an LCD. Its three 16-bit sigma-delta ADCs are useful for low-bandwidth analog measurement channels, while the 8 MHz MSP430 CPU handles sampling control, filtering, threshold decisions, and data formatting. The five low-power modes and less-than-6-microsecond standby wake-up statement support duty-cycle strategies for battery-operated or remotely powered systems. A practical design can disable the display and unused peripherals between measurements, then wake the MCU for a new conversion cycle. Sensor excitation, ADC input conditioning, calibration coefficients, and enclosure-related temperature behavior are not specified in the verified data and require application-level design.
おすすめ
Portable Measurement Equipment
MSP430F423IPM supports portable measurement equipment when a product needs local sensing, a compact display, and restrained energy use. The 16-bit RISC CPU and three 16-bit sigma-delta ADCs can be used for sensor acquisition and measurement processing, while the 128-segment LCD interface reduces the display-controller burden. The 2.7 V to 3.6 V operating range is compatible with many 3.3 V portable architectures, subject to the complete power-budget design. Five power-saving modes allow firmware to reduce activity during idle periods, and the verified standby wake-up figure is less than 6 microseconds. Designers should verify LCD glass requirements, ADC settling behavior, battery chemistry, and regulator dropout using the manufacturer datasheet rather than relying on the product summary alone.
おすすめ
Battery-Powered Metering
MSP430F423IPM is appropriate for battery-powered metering when the design values low active current and rapid wake-up. The five power-saving modes, 256 B RAM, 8 KB Flash, and integrated LCD support allow a compact controller to alternate between measurement, display, and standby states. The three 16-bit sigma-delta ADCs can support multiple low-bandwidth sensing channels, while the 48 I/O ports provide connections for buttons, indicators, and external interfaces. A practical firmware strategy is to configure the required peripherals, take measurements, update the LCD, then return the device to a low-power state. The verified data does not provide active or standby current values, regulator efficiency, or battery-life estimates, so those figures must be obtained from the current datasheet and measured in the final system.
おすすめ
LCD-Based Control Interface
MSP430F423IPM can act as the central controller for an LCD-based operator interface because it combines 128-segment LCD support with 48 I/O ports and an 8 MHz 16-bit RISC CPU. Firmware can read front-panel controls, update the display, supervise external sensors, and coordinate simple actuator signals. The 2.7 V to 3.6 V supply range permits integration with common embedded logic, while the five power-saving modes can reduce display and control activity when the panel is idle. The 64-LQFP footprint is appropriate for a dedicated controller board, but LCD segment drive characteristics and pin multiplexing must be checked against the exact pin table. Do not infer LCD voltage, bias, or segment assignment from the 128-segment feature alone.

設計ノート
Use the manufacturer pin table as the authoritative source for the 64-LQFP footprint, because the verified distributor data confirms the package and pin count but does not provide individual pin names. Place decoupling and support components according to the current datasheet layout guidance, keep sensitive analog routing away from switching nodes, and preserve a clean return path for the ADC and LCD circuitry. Do not infer analog, LCD, or ground assignments from package position alone.
The verified operating range is 2.7 V to 3.6 V, so design the supply and external interface levels around that range. Check regulator tolerance, startup behavior, and current budget against the complete system rather than relying only on the nominal 3.3 V use case. For battery-powered designs, measure active, idle, and standby current in firmware because the supplied data does not provide numeric current values.
The five power-saving modes and less-than-6-microsecond standby wake-up specification can support duty-cycled sensing. Configure unused peripherals and LCD segments for the lowest applicable power state, then wake the MCU for scheduled measurements. Validate wake timing, display settling, sensor recovery, and ADC sampling behavior in the final firmware because these application-level timings are not fully specified in the verified web data.
Keep analog sensor inputs short, properly referenced, and separated from fast digital or switching signals. The verified data confirms three 16-bit sigma-delta ADCs but does not provide input impedance, reference requirements, or acquisition timing, so use the manufacturer electrical characteristics to select series resistance, filtering, and grounding. Validate offset, gain, noise, and calibration across the intended operating range.
コンプライアンス情報
The verified product data identifies the device as an industrial-range microcontroller and does not provide RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals declarations. Verify current compliance documents with Texas Instruments or the authorized distributor.
