MSP430F436IPZ - 8MHz 16-Bit MCU with 24KB Flash | Texas Instruments
部品番号: MSP430F436IPZ ✓ 生産中MSP430F436IPZ 概要
A microcontroller is a programmable integrated circuit that combines a CPU, memory, and peripherals on one semiconductor device. The MSP430F436 belongs to the MSP430 mixed-signal microcontroller family, where the MSP430x4xx architecture adds higher-performance mixed-signal capabilities while retaining the low-power design focus of the MSP430 product line. Its 16-bit RISC core uses 16-bit registers and constant generators for efficient control operations.
Key features include an 8 MHz maximum clock, 24 KB of programmable Flash, 1 KB of SRAM, and 48 I/O pins. The mixed-signal resources include a 12-bit ADC and comparator, while communications and timing resources include SPI, UART/USART, PWM, watchdog timer, and brown-out detection/reset. A 160-segment LCD driver supports display-oriented industrial, meter, and measurement equipment.
The MSP430 architecture is designed around low-power operation, making the device suitable for battery-operated and intermittently powered products. Peripherals and the CPU can be controlled to reduce activity when measurements are not required. The 100-pin LQFP package provides substantially more I/O and peripheral routing flexibility than smaller microcontroller packages, although its 14 mm by 14 mm body requires more PCB area than compact QFN options.
Typical applications include industrial panel meters, data loggers, portable measurement instruments, environmental monitoring equipment, battery-powered sensors, and LCD-driven control panels. The ADC supports analog measurement, the comparator supports threshold-based detection, and SPI or UART/USART provides a path to external sensors, memory, displays, or host systems. The integrated LCD capability is especially useful for local numeric or segmented status displays.
Designers should verify the exact pin assignments, analog input multiplexing, LCD segment mapping, and peripheral channel allocation against the manufacturer pinout before PCB routing. The LQFP perimeter is fine-pitch, so careful pad design, solder mask control, and assembly inspection are important. Firmware should also account for the MSP430 clock setup, ADC conversion sequence, brown-out behavior, and low-power state transitions.
This product page combines verified manufacturer and distributor specifications, same-family replacement analysis, package details, and practical design guidance. It is intended to help engineers confirm whether the MSP430F436IPZ matches the required memory, analog, communications, display, package, and low-power requirements before procurement or layout release.

主な用途
MSP430F436IPZ の用途: 6 件s: Industrial Panel Meter, Portable Environmental Sensor, Battery-Powered Data Logger, LCD-Driven Control Panel, Medical and Diagnostic Instrument, SPI-Based Sensor Node.
Industrial Panel Meter
The MSP430F436IPZ fits an industrial panel meter because it combines a 12-bit ADC, comparator, 48 I/O pins, and support for a 160-segment LCD in one 100-pin LQFP device. The ADC can sample a conditioned sensor signal, while the comparator can support threshold or protection functions. Its 24 KB Flash provides room for calibration, display formatting, and communication firmware, and the 1 KB SRAM can support working state and display buffers. Using the integrated LCD controller can reduce external display-driver complexity, although the exact segment mapping must be confirmed in the manufacturer pinout. For a production design, verify ADC input impedance, acquisition timing, operating voltage, temperature range, and protection requirements for the industrial environment.
おすすめ
Portable Environmental Sensor
The MSP430F436IPZ is appropriate for a portable environmental sensor that periodically measures an analog signal and reports results through a serial interface. Its 12-bit ADC provides useful resolution for many temperature, humidity, gas, and pressure front ends, while the comparator can support threshold events or simple signal-presence detection. The MSP430 architecture's low-power emphasis supports duty-cycled operation in battery-powered equipment, and 24 KB of Flash can hold measurement routines, compensation, and protocol handling. The 1 KB SRAM may constrain large data buffers, so streaming designs should avoid retaining unnecessary samples. Battery life must be calculated from the actual operating-voltage limits, selected low-power mode, wake-up latency, and sensor duty cycle because those values were not included in the supplied excerpts.
おすすめ
Battery-Powered Data Logger
The MSP430F436IPZ can serve as the control and communications core of a battery-powered data logger. Its 24 KB Flash and 1 KB SRAM provide sufficient space for compact acquisition code, event records, and serial protocols, while the 12-bit ADC supports analog sensor channels. SPI or UART/USART can connect to flash storage, an external sensor, or a host computer. The LCD support is useful in portable instruments that show local status without keeping a display continuously active. In a duty-cycled logger, firmware can wake the device, sample, store, transmit, and return to a low-power state. Designers should confirm that the selected memory size accommodates the desired logging depth and that the power-management strategy meets the available battery voltage and temperature limits.
おすすめ
LCD-Driven Control Panel
The MSP430F436IPZ fits a local human-interface control panel with up to 160 LCD segments and 48 I/O pins. The integrated segment capability can support numerical readouts, status indicators, and simple menus, while the comparator and ADC can monitor analog panel signals. Its 8 MHz MSP430 CPU provides control bandwidth for keypad or switch handling, display updates, and communication tasks, and the 100-pin LQFP offers ample routing options for mixed analog and digital functions. Using the LCD controller can reduce the number of external driver components, but segment assignment, common-drive arrangement, bias voltage, and LCD timing must follow the exact device documentation. Mechanical button debouncing, ESD protection, and EMI margin around the display connector also require board-level attention.
おすすめ
Medical and Diagnostic Instrument
The MSP430F436IPZ can support compact medical and diagnostic instruments that combine a modest analog measurement with local controls and a low-power processor platform. The 12-bit ADC can acquire outputs from suitable sensor front ends, while the comparator supports thresholding and simple protection functions. The 24 KB Flash and 1 KB SRAM are appropriate for focused firmware rather than large buffering workloads, and the LCD driver can present compact status information. Because the supplied records do not state the operating-voltage range, medical-suitability claims, isolation capability, or safety qualification, these must not be inferred. A compliant design would need separate review of electrical isolation, leakage, EMC, patient-contact protection, risk controls, and the applicable medical regulatory process.
おすすめ
SPI-Based Sensor Node
The MSP430F436IPZ is suitable for a sensor node that uses SPI to communicate with a high-resolution sensor or external memory. The 16-bit MSP430 CPU can service sensor transactions, apply calibration, and manage low-power duty cycles, while the 12-bit ADC can provide an additional independent measurement path. The 48 available I/O pins allow the design to integrate multiple chip selects, interrupts, status indicators, and serial communication without relying on a small-package microcontroller. The 100-pin LQFP footprint increases routing flexibility but also demands careful escape routing from its 0.5 mm pitch leads. SPI clock polarity, maximum bus rate, input thresholds, and power sequencing must be checked for the connected device. Firmware should also provide fault handling for sensor timeouts and bus contention.

設計ノート
Route the 100-pin LQFP using the manufacturer-recommended land pattern and verify pad dimensions against the current package drawing. Keep analog inputs away from SPI/UART traces, LCD outputs, switching supplies, and high-current return paths. Provide a continuous ground reference beneath and around the device, use short return paths for decoupling, and place the input, output, and reference capacitors directly at their associated pins. Because the supplied records do not include the complete pinout or recommended capacitor values, confirm both items in the MSP430F436 documentation before release.
Design the power rails around the verified operating-voltage limits rather than assumptions from another MSP430 device. Confirm the required VCC range, ADC reference voltage, LCD bias requirements, and maximum supply ramp conditions in the official datasheet. Place bypass capacitors close to the supply and ground terminals, maintain the required loop area, and account for startup current, brown-out reset behavior, and any load-switch sequencing. The quoted operating voltage was unavailable in the supplied excerpts, so a regulator should not be selected from this page alone.
Treat SPI, UART/USART, and LCD signals as potentially vulnerable to noise from adjacent analog or switching circuitry. Maintain continuous ground references, avoid routing communication traces across split power planes, and use series termination only when signal-integrity analysis or measured ringing indicates it is required. The comparator and ADC inputs should have controlled source impedances and defined settling times. Firmware must also allow sufficient acquisition and settling time; nominal ADC bit depth alone does not guarantee accurate field measurements.
Do not treat a shared 100-pin LQFP footprint as proof that every MSP430x4xx model is an unconditional drop-in replacement. Before substituting MSP430F435IPZ, MSP430F4361IPZ, MSP430F437IPZ, MSP430F4371IPZ, or MSP430F4351IPZ, compare the complete pin table, power pins, analog-channel assignment, LCD mapping, clock requirements, memory map, interrupt vectors, and peripheral behavior. Also validate compiler, linker, and startup-code changes if the alternative has a different vector table or peripheral configuration.
コンプライアンス情報
The supplied verified records identify the MSP430F436IPZ as an active Texas Instruments mixed-signal MCU but do not explicitly provide RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals declarations.
