MSP430F5438AIZQWT - 25MHz 256KB Mixed-Signal MCU | TI
Référence : MSP430F5438AIZQWT ✓ ActifMSP430F5438AIZQWT Présentation
A mixed-signal microcontroller is a semiconductor that combines a digital processor, memory, and analog or communication peripherals on one device. The MSP430 belongs to the low-power MCU hierarchy and is designed for embedded control, measurement, communications, and battery-operated systems where efficient code execution and multiple low-power operating modes are important. This part is positioned between a general-purpose microcontroller and a dedicated signal-processing controller.
Verified features include a 2.4 V to 3.6 V supply range, 25 MHz clock speed, 256 KB flash, 16 KB SRAM, 31 I/O ports, and a 12-bit ADC. The datasheet search data also identifies ultra-low-power modes including LPM3 with watchdog timer and LPM4 with RAM retention/off-related operation. The available product information further confirms UART, SPI, I2C, DMA, timers, and hardware-multiplier support, making the MCU suitable for connected industrial, sensor, and embedded-control designs.
The device uses a mixed-signal architecture rather than a dedicated analog signal-processing front end. Its ADC supports embedded measurements, while serial interfaces allow connection to sensors, transceivers, memories, and human-interface modules. The 256 KB flash capacity provides substantially more program storage than smaller MSP430 devices, while the 16 KB SRAM supports working state, buffers, stacks, and peripheral data handling.
Typical applications include industrial sensor nodes, low-power data loggers, building-control equipment, battery-powered monitors, communications equipment, and compact embedded systems. The 113-ball Microstar Junior package supports dense PCB layouts, but its ball pitch, exposed thermal requirements, assembly process, and layout rules must be checked against the official package drawing before layout.
For a robust design, confirm the exact package pinout, power sequencing, decoupling requirements, clock configuration, ADC reference, and low-power wake-up behavior in the manufacturer datasheet. This page distinguishes verified values from parameters requiring project-specific confirmation and avoids treating distributor snippets as complete electrical specifications.

Applications typiques
MSP430F5438AIZQWT convient pour 6 applications: Industrial Sensor Nodes, Battery-Powered Environmental Monitoring, Industrial Communications Gateway, Building Automation Equipment, Portable Measurement Instrument, Data Logger with Local Storage.
Industrial Sensor Nodes
The MSP430F5438AIZQWT fits industrial sensor nodes that combine periodic analog measurement with low-power serial communications. Its verified 12-bit ADC can sample transducers or resistive sensors, while 31 I/O ports support discrete inputs, indicators, and actuator-control signals. The 256 KB flash provides room for application firmware, calibration tables, and protocol handlers, and the 16 KB SRAM can hold acquisition buffers and working state. Duty-cycle the MCU between measurement and idle periods to exploit its verified ultra-low-power architecture and 180 uA/MHz active-mode figure.
Recommandé
Battery-Powered Environmental Monitoring
Use the MSP430F5438AIZQWT in battery-powered environmental monitors when the design needs local analog sensing, data buffering, and intermittent communications. The 12-bit ADC supports sensor conditioning, and the 2.4 V to 3.6 V supply range fits low-voltage systems that remain within the specified rail limits. The verified ultra-low-power positioning and LPM3/LPM4 references make duty-cycled operation a natural fit for temperature, humidity, air-quality, or light monitoring. Average current must be validated against wake-up sources, sensor load, and radio activity because only part of the power profile is supplied in the verified snippets.
Recommandé
Industrial Communications Gateway
The MSP430F5438AIZQWT can serve as a compact communications controller when a board needs UART, SPI, and I2C alongside local mixed-signal measurement. Its verified 25 MHz 16-bit core provides compute headroom for protocol framing and control logic, while DMA can move peripheral data with less CPU intervention. The 256 KB flash is useful for protocol stacks, configuration data, and diagnostic code. Designers should verify UART baud-rate limits, SPI timing, I2C electrical limits, and pin multiplexing in the official datasheet before finalizing the interface rate.
Recommandé
Building Automation Equipment
The MSP430F5438AIZQWT is suitable for building-automation controllers that combine sensor inputs, local logic, and low-power field-bus communication. Its 31 I/O ports can support digital status and control functions, while the ADC can read environmental or occupancy-related analog signals. The 256 KB flash allows firmware for scheduling, calibration, diagnostics, and communication protocols, and the 16 KB SRAM can support state machines and data buffering. Because the verified package is a 113-ball BGA, layout planning must account for ball pitch, escape routing, assembly capability, and thermal spreading.
Recommandé
Portable Measurement Instrument
The MSP430F5438AIZQWT can be used in portable measurement instruments where an embedded controller must acquire analog signals, run calibration logic, and communicate with a host. The 12-bit ADC and mixed-signal feature set help reduce the need for separate control components, while the 25 MHz CPU supports responsive sampling and data processing. The 2.4 V to 3.6 V range supports low-voltage portable systems when regulator and battery limits are respected. Confirm ADC input impedance, acquisition time, reference stability, and package-specific routing before defining measurement accuracy.
Recommandé
Data Logger with Local Storage
The MSP430F5438AIZQWT can serve as the control processor in a compact data logger with local flash, sensor interfaces, and intermittent communications. Its 256 KB internal flash stores firmware and calibration data, while the 16 KB SRAM can hold records and working buffers. UART, SPI, and I2C provide options for connecting sensors, memory, or a host interface, and DMA can reduce CPU involvement during transfers. The part is especially useful when low standby activity matters, but the actual battery life depends on sampling rate, storage write frequency, communication bursts, and board leakage.

Notes de conception
Treat the 113-ball Microstar Junior BGA as a layout-critical package. Before routing, obtain the official ball map and land pattern, verify the 7 mm by 7 mm package dimensions, and confirm the assembly process's ball-pitch and via-in-pad requirements. Keep decoupling close to the supply and ground balls, provide a continuous ground reference where the package drawing permits, and route high-speed or sensitive ADC signals away from switching nodes. The verified search data does not include the full pin map, so do not infer ball assignments from the BGA name alone.
Design the supply around the verified 2.4 V to 3.6 V operating range and validate startup, brownout, and load-transient behavior against the official datasheet. Place the required bypass capacitors at the device power balls with short ground returns, and confirm the regulator's startup sequence before enabling dependent circuits. For battery-powered designs, calculate average current from the 180 uA/MHz active-mode reference plus sleep current, wake-up behavior, sensor load, and communications duty cycle; only the active-mode figure is explicitly present in the supplied data.
Do not approve a replacement based only on the shared MSP430F5438A family name or a distributor search result. Verify the exact ordering suffix, ball assignment, power and ground connectivity, exposed thermal structure, temperature range, and firmware-relevant peripheral configuration in the TI datasheet and ordering information. The cross-reference evidence confirms that MSP430F5438AIPZ is also associated with a 113-ball BGA Microstar Junior package, but it does not establish every suffix-level compatibility requirement.
Informations de conformité
The supplied verified web data does not explicitly state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. These fields must be confirmed from the current TI product documentation or supplier declarations.
