Артикул: MSP430F5438IPZR ✓ АктивенMSP430F5438IPZR Обзор
A mixed-signal microcontroller combines a digital processor core with analog and communication peripherals, allowing one device to control sensors, communications, timers, and power sequencing. The MSP430 belongs to the microcontroller -> embedded processor -> semiconductor hierarchy and is designed for battery-powered and industrial systems that require efficient computation and broad peripheral integration.
The verified manufacturer and distributor information identifies the MSP430F5438 family with 25-MHz operation, 256-KB flash, 16-KB SRAM, a 12-bit ADC, DMA, UART, SPI, I2C, timers, and a hardware multiplier. These resources support mixed-signal acquisition, data movement, motor and timer control, sensor conditioning, and low-power embedded products.
The MSP430F5438IPZR ordering code identifies the 100-LQFP, 14 x 14 mm package and the IPZR package/reel ordering variant. The distributor listing also identifies the CPUXV2 MSP430F5xx microcontroller class. The available verified data does not include the complete electrical limits, ADC timing, memory-map details, GPIO count, or pin names, so those values must be confirmed in the manufacturer datasheet before design release.
Typical uses include industrial sensor nodes, portable measurement equipment, data-acquisition systems, communications controllers, low-power industrial controls, and embedded motor or timer systems. The integrated ADC and communication peripherals can reduce external component count, while the large flash and SRAM footprint supports firmware, protocol stacks, buffering, and application logic.
Design with the MSP430F5438IPZR by confirming the exact pinout, power-supply limits, clock configuration, reset behavior, and peripheral multiplexing in the TI datasheet. Keep analog inputs, supply returns, and high-speed communications appropriately routed on the PCB, and validate low-power modes against the application’s wake-up and measurement requirements.
This page consolidates verified manufacturer and distributor information, package data, commercial search results, and engineering-oriented application guidance. It intentionally identifies missing electrical details rather than estimating them, helping engineers distinguish documented facts from values that require final datasheet verification.

Типичное применение
MSP430F5438IPZR подходит для 7 применениеs: Industrial Sensor Node, Portable Measurement Instrument, Low-Power Communications Controller, Data-Acquisition System, Timer-Based Motor Control, Smart Home Sensor Hub, Embedded Control and Logging.
Industrial Sensor Node
The MSP430F5438IPZR fits industrial sensor-node designs because its 16-bit CPU operates up to 25 MHz while providing 256 KB of flash and 16 KB of SRAM for local control and data buffering. The integrated 12-bit ADC can acquire analog sensor information, while DMA can move data with less CPU intervention. UART, SPI, and I2C provide paths to external sensors, radios, or local storage. The design should verify the ADC channel count, sampling rate, operating-temperature range, and supply limits in the TI datasheet before deployment.
Рекомендуется
Portable Measurement Instrument
For portable measurement equipment, MSP430F5438IPZR combines a 12-bit ADC with 16 KB of SRAM and 256 KB of flash, allowing sampled data, calibration logic, and a user interface to share one controller. The low-power-oriented MSP430 architecture is useful in battery-operated instruments where duty cycling and wake-up behavior matter. The 100-LQFP package provides a substantial pin count for controls, displays, and communications, but the exact power modes, ADC timing, and temperature limits must be confirmed before final battery sizing.
Рекомендуется
Low-Power Communications Controller
MSP430F5438IPZR is appropriate for a communications controller when firmware, protocol buffering, and timing functions must coexist in a compact MCU. UART, SPI, and I2C are listed as integrated peripherals, while the 16-bit CPU and hardware multiplier support protocol processing and control tasks. DMA can reduce interrupt pressure during transfers. The actual baud-rate limits, electrical timing, peripheral instance count, and pin multiplexing must be validated from the manufacturer datasheet for the selected board architecture.
Рекомендуется
Data-Acquisition System
The MSP430F5438IPZR’s 12-bit ADC, DMA support, 256-KB flash, and 16-KB SRAM provide a useful foundation for embedded data-acquisition systems. DMA can transfer sampled data while the CPU performs filtering, calibration, and host communication, while flash can hold firmware and parameters. SPI and UART can connect to sensors, converters, or a computer. The design must establish the required sample rate, input impedance, acquisition timing, and analog front-end limits from the full TI datasheet rather than relying only on the family-level summary.
Рекомендуется
Timer-Based Motor Control
The MSP430F5438IPZR can serve as the control processor in timer-based motor and actuator systems because it integrates timers, DMA, a 12-bit ADC, and multiple serial interfaces. Timers can establish deterministic control intervals, ADC conversions can monitor current or position-related analog signals, and UART or SPI can connect to a driver or supervisor. Exact timer resolution, PWM outputs, ADC latency, and pin assignments are not included in the supplied data and must be confirmed for the exact firmware and safety requirements.
Рекомендуется
Smart Home Sensor Hub
MSP430F5438IPZR can serve as the local controller in a smart-home sensor hub where low-power processing, analog sensing, and short-range serial connectivity are needed. The 256 KB of flash provides room for firmware and protocol logic, while 16 KB of SRAM supports buffering and state management. I2C and SPI suit sensors and display or storage devices, and UART can connect to a gateway. The system should confirm operating-temperature limits, standby behavior, and all exposed I/O before using the MCU in a safety-relevant or permanently installed product.
Рекомендуется
Embedded Control and Logging
The MSP430F5438IPZR is suitable for embedded control and logging products that need a microcontroller with both analog input and serial connectivity. Its 12-bit ADC supports analog measurements, the hardware multiplier assists arithmetic-intensive control tasks, and DMA supports efficient data movement. Flash can store firmware and configuration, while SRAM can hold active logs and protocol buffers. The 100-LQFP package offers many external connections, but the exact pin map, power budget, and peripheral limits require manufacturer verification.

Заметки по проектированию
The verified data confirms a mixed-signal MCU but does not provide the complete supply-voltage range or absolute maximum ratings. Before applying power, verify the exact VCC requirements, decoupling recommendations, analog-supply arrangement, and reset requirements in the manufacturer datasheet. Place required bulk and bypass capacitors according to the TI guidance and keep return-current paths short; do not infer power values from a related MSP430 device.
Use the official 100-LQFP pin drawing and datasheet pin-multiplexing tables to assign analog inputs, communication signals, clocks, and control outputs. Keep sensitive ADC traces away from switching nodes and high-current return paths, route serial interfaces with controlled impedance where required, and place external support components close to the pins they serve. Because the verified data does not provide the complete pin map, a footprint-only substitution review is insufficient.
Do not treat MSP430F5438, MSP430F5438A, or a distributor package suffix as a proven drop-in replacement without checking the exact ordering table. Confirm memory size, package, pin multiplexing, supply limits, peripheral availability, temperature range, and software device identification. The verified results establish family-level features, but they do not establish complete electrical equivalence for every alternative MPN.
Информация о соответствии
The supplied verified product and distributor snippets do not provide authoritative RoHS, REACH, lead-free, halogen-free, conflict-minerals, or automotive-qualification statements. Compliance must be confirmed from the current manufacturer product documentation and supply-chain declarations.
