MSP430F415IPM - 8MHz 16-Bit MCU with 16KB Flash | Texas Instruments
部品番号: MSP430F415IPM ✓ 生産中MSP430F415IPM 概要
An ultra-low-power microcontroller is a semiconductor designed to complete control tasks while minimizing energy consumption during active operation and idle periods. The MSP430 architecture belongs to the embedded microcontroller hierarchy and combines a 16-bit RISC CPU, 16-bit registers, constant-memory instruction execution, and five low-power operating modes. These characteristics make it useful where battery life, deterministic control, and compact peripheral integration are more important than high processor throughput.
The MSP430F415IPM provides 16 KB of Flash for firmware, 512 bytes of SRAM for working data, a timer, a comparator, and a 96-segment LCD driver. Its 48 I/O pins support external sensing, control, and display interfaces. The 8 MHz maximum clock provides processing headroom for measurement and control tasks, while the integrated LCD and analog comparison functions can reduce the component count in handheld meters and industrial panel instruments.
Five low-power modes support battery-conscious operation, and the manufacturer describes the architecture as optimized for extended battery life in portable measurement applications. The mixed-signal feature set allows software to process digital control functions alongside analog comparisons. According to the Texas Instruments product information, the device combines a powerful 16-bit RISC CPU with 16-bit registers and constant-memory execution, providing a compact platform for embedded signal acquisition and user-interface control.
Typical uses include utility meters, industrial measurement panels, portable data loggers, handheld testers, sensor-conditioning systems, and low-power control boards. The 96-segment LCD capability is especially useful in devices that need a numeric or segmented display without requiring a graphical LCD controller. The 48 available I/O ports also allow designers to connect sensors, switches, relays, and communication peripherals while retaining local processing capability.
Designers should verify the complete 64-pin signal assignment against the manufacturer datasheet and keep decoupling close to the power pins. Because the MCU operates from 2.7 V to 3.6 V, external sensors and interface circuits must use compatible voltage levels or appropriate level translation. Low-power performance also depends on firmware, because interrupt-driven sleep modes and peripheral clock control usually determine the final battery life.
This page consolidates verified manufacturer and distributor information, distinguishes documented specifications from unavailable data, and provides application guidance and drop-in alternatives for engineers evaluating the MSP430F415IPM.

主な用途
MSP430F415IPM の用途: 6 件s: Portable Utility Meter, Industrial Handheld Tester, Low-Power Sensor Node, Segmented-Display Control Panel, Battery-Powered Data Logger, Process and Threshold Monitor.
Portable Utility Meter
The MSP430F415IPM fits portable utility meters because its 96-segment LCD driver can present measurement results directly, while the 8 MHz 16-bit RISC CPU handles sampling, calculation, and user input. Its 16 KB of Flash provides dedicated firmware space and 512 bytes of SRAM supports short working buffers. The 2.7 V to 3.6 V operating range is appropriate for a dedicated battery-regulated rail. Five low-power modes can reduce consumption between measurement intervals, although final battery life depends on sensor and display duty cycles. The 48 I/O ports also provide flexibility for pulse inputs, tamper detection, configuration switches, and alarm outputs without requiring a separate display driver.
おすすめ
Industrial Handheld Tester
The MSP430F415IPM suits industrial handheld testers where a segmented display, responsive local controls, and low standby consumption are required. Its timer and comparator support timing, threshold, and event-based measurements, while the 8 MHz CPU can supervise sensor inputs and apply calibration data stored in the 16 KB Flash memory. Forty-eight I/O pins allow the enclosure to include switches, status LEDs, and external probes. The 64-LQFP 10 x 10 mm package provides a practical footprint for a dense handheld PCB. Five operating modes allow firmware to remain largely asleep between readings, while the industrial classification supports use in controlled industrial environments when the complete electrical and temperature requirements are satisfied.
おすすめ
Low-Power Sensor Node
The MSP430F415IPM is appropriate for a low-power sensor node that periodically acquires measurements and spends most of its time in an MSP430 low-power mode. Its 16-bit RISC architecture and 8 MHz clock are sufficient for sensor conditioning, filtering, and threshold decisions without a larger processor. The integrated comparator can support simple threshold events and wake decisions, reducing the need for a separate comparator. Its 512-byte SRAM constrains buffered data, so applications requiring extensive history should store samples externally or use a higher-memory MCU. The 2.7 V to 3.6 V supply range also supports direct integration with low-energy 3 V sensor platforms when their voltage limits match.
おすすめ
Segmented-Display Control Panel
The MSP430F415IPM can control a compact industrial panel because it integrates a 96-segment LCD driver alongside 48 I/O ports. That combination reduces the need for an external LCD controller in applications using numeric, alphanumeric segment, or indicator-based displays. The 8 MHz processor can handle debouncing, menu logic, status monitoring, and output control while the 16 KB Flash stores firmware. Five low-power modes are useful when the panel sleeps between operator interactions. Engineers should confirm segment mapping, glass bias requirements, and multiplexing constraints in the manufacturer documentation. If the display requires dot-matrix graphics rather than segmented indication, a different MCU with a dedicated LCD or display interface will be required.
おすすめ
Battery-Powered Data Logger
The MSP430F415IPM supports battery-powered data logging when the log must be acquired, summarized, and displayed without a continuously active processor. Its five low-power modes allow scheduled acquisition and interrupt-driven sleep, while the 16-bit CPU performs calculations over sampled data. The 512-byte SRAM is suitable for short working sets but may not hold large records, so the firmware should use compact formats or external nonvolatile storage. The 96-segment LCD is useful for displaying current readings, status, and battery information. Because the provided data does not contain a complete mode-current table, battery-life calculations should use manufacturer measurements under the intended temperature, supply voltage, display loading, and sampling interval.
おすすめ
Process and Threshold Monitor
The MSP430F415IPM fits a compact process monitor that compares a measured signal against a threshold and controls local outputs. Its integrated comparator can perform the initial threshold operation, while the timer and 8 MHz CPU support periodic sampling, debouncing, alarms, and event logging. The 16 KB Flash and 512-byte SRAM are sufficient for compact embedded control logic, and the 48 I/O ports provide connections for sensor inputs and relay or indicator outputs. The 2.7 V to 3.6 V operating range simplifies integration with industrial 3 V signal chains when electrical compatibility is confirmed. Safety-related installations still require suitable isolation, protection, and diagnostic circuitry beyond the MCU itself.

設計ノート
The verified operating range for MSP430F415IPM is 2.7 V to 3.6 V. Confirm that every externally connected sensor, communications interface, and display driver either supports that range or is protected by an appropriate level translator. Place the closest bypass capacitor at the MCU supply pins and keep sensitive analog and LCD connections away from fast-switching return currents. Final standby and active-current budgets should use the manufacturer mode-current table because the supplied listing does not provide a complete current profile.
The 64-LQFP 10 x 10 mm footprint has fine-pitch leads and limited escape routing, so assign pins to functional groups before laying out the PCB. Keep the LCD segment connections away from sensitive comparator inputs, place decoupling at the power entry points, and route high-current outputs separately from analog returns. Verify courtyard clearance, exposed thermal requirements, and assembly rules against the official package drawing rather than relying only on the distributor package name.
Do not treat 512 bytes of SRAM as general-purpose data storage. Concurrent interrupt handlers, stack frames, display buffers, and communication buffers can exhaust it quickly. Measure worst-case stack depth with representative firmware and avoid placing large tables in RAM. Similarly, confirm the 16 KB Flash budget for boot code, application code, constants, and update routines because the verified product data does not indicate dedicated bootloader space.
For portable measurement products, establish a repeatable low-power control sequence: disable unused peripherals, stop their clocks, enter the lowest approved sleep mode, and use an interrupt or timer event to resume. The comparator, timer, and LCD driver can consume resources if left active. Validate average current with the intended display illumination and sensor duty cycle because software scheduling usually has a larger effect on battery life than the nominal processor frequency.
コンプライアンス情報
The verified data identifies the MSP430F415IPM as an active industrial device but does not state RoHS, REACH, lead-free, halogen-free, conflict-minerals, or AEC-Q100 status. AEC-Q100 is marked not_applicable because no automotive qualification is claimed; it must not be inferred from the industrial temperature classification.
