MSP430F249TPM - 16MHz, 60KB Flash RISC MCU | Texas Instruments
Teilenummer: MSP430F249TPM ✓ AktivMSP430F249TPM Übersicht
A microcontroller is a programmable system-on-chip that executes firmware, reads sensors, controls outputs, and manages communications. The MSP430 belongs to the mixed-signal microcontroller hierarchy and combines a 16-bit RISC CPU with analog peripherals and low-power modes. Its architecture is designed for battery-powered instruments where efficient standby operation and rapid wake-up help extend operating time.
Key features include a 16-bit CPU with 16-bit registers, 60 KB Flash, 2 KB SRAM, a 12-bit ADC, a comparator, communication interfaces supporting I2C, SPI, and UART, and a hardware multiplier. The 16 MHz maximum clock supports responsive control and signal-processing workloads while the low-power design remains suitable for portable measurement systems. The manufacturer lists the MSP430F249 as an ultra-low-power device with multiple low-power modes.
The mixed-signal architecture allows digital control and analog measurement to share one device, reducing component count in sensor nodes and industrial instruments. The ADC supports measurement channels while the comparator can support threshold and signal-monitoring functions. Serial interfaces allow connection to sensors, displays, transceivers, and external data converters without requiring multiple dedicated interface devices.
Typical uses include battery-powered data loggers, handheld meters, industrial monitoring nodes, environmental sensing, portable medical equipment, and embedded measurement systems. Designers should verify the exact pin functions, operating voltage, peripheral limits, and timing requirements against the manufacturer datasheet before final PCB release.
For low-power designs, activate the appropriate sleep mode when the acquisition and communication schedule allows it, then use the device’s wake-up behavior to resume processing. Place decoupling capacitors close to the supply pins and route high-current and sensitive analog signals away from switching nodes. This page combines distributor availability, manufacturer specifications, replacement analysis, and practical design guidance for engineers evaluating the MSP430F249TPM.
The verified distributor listing identifies the MSP430F249TPM as a 16-bit, 16 MHz MSP430F2xx microcontroller with 60 KB Flash and a 64-LQFP package. The Texas Instruments product page additionally identifies 2 KB SRAM, a 12-bit ADC, comparator, I2C/SPI/UART, and hardware multiplier features.

Typische Anwendungen
MSP430F249TPM ist geeignet für 6 Anwendungs: Battery-Powered Data Logger, Industrial Sensor Monitoring, Portable Environmental Sensor, Handheld Meter, Embedded Communications Controller, Medical or Portable Diagnostic Instrument.
Battery-Powered Data Logger
The MSP430F249TPM fits portable data-logging systems because its 16 MHz 16-bit RISC core can process samples while its five low-power modes support reduced activity between measurement events. The 60 KB Flash stores firmware and local data, while 2 KB SRAM supports acquisition and buffering. Use the ADC for sensor inputs and I2C or SPI for external sensors or memory. Validate average current with the actual sampling interval, sensor load, and wake-up schedule.
Empfohlen
Industrial Sensor Monitoring
MSP430F249TPM is suitable for monitoring nodes that combine analog measurement with local control and serial reporting. Its 12-bit ADC and comparator support threshold-based sensing, while I2C, SPI, and UART provide paths to sensors and gateways. The listed -40 °C to +105 °C range is useful for extended-temperature environments. Confirm channel counts, input limits, isolation, EMC performance, and enclosure thermal conditions in the final design.
Empfohlen
Portable Environmental Sensor
The MSP430F249TPM can coordinate temperature, humidity, gas, or motion sensing in a compact battery-powered node. The mixed-signal MCU integrates the ADC, comparator, and serial interfaces, reducing the need for separate interface circuitry. Its 2 KB SRAM limits buffering capacity, so applications should use streamed sampling or external nonvolatile storage when long records are required. Low-power mode selection and sensor duty cycle determine practical battery life.
Empfohlen
Handheld Meter
MSP430F249TPM provides the processing and mixed-signal resources needed for a handheld measurement instrument. The 16-bit RISC CPU handles control logic, the 12-bit ADC supports analog measurement, and the hardware multiplier assists arithmetic operations. UART or SPI can connect to a display, data storage, or a wired interface. Use the low-power modes between readings and verify battery regulator behavior, display current, and calibration requirements.
Empfohlen
Embedded Communications Controller
The MSP430F249TPM can serve as a low-power communications controller when the application needs local control alongside UART, SPI, or I2C connectivity. Its 16 MHz processor provides timing headroom for protocol handling, while Flash supports firmware and configuration storage. Select the communication transceiver separately and verify voltage levels, line protection, baud-rate tolerance, and low-power wake-up behavior. Firmware partitioning should account for the 2 KB SRAM limit.
Empfohlen
Medical or Portable Diagnostic Instrument
MSP430F249TPM is applicable to compact measurement instruments where low power, analog input capability, and local serial connectivity matter. The integrated 12-bit ADC can acquire sensor signals, while the comparator supports threshold detection and the CPU manages calibration and control. Medical applications require additional system-level validation, including electrical safety, accuracy, isolation, and applicable regulatory requirements; none of those requirements are established by the supplied component data.

Wichtigste Unterscheidungsmerkmale
- Verified 60 KB Flash and 2 KB SRAM configuration (vs. MSP430F248TPM)

Designhinweise
Design the supply network for the verified 2.5 V or 3.3 V operating options and place local bypass capacitors close to the MSP430F249TPM supply pins. Use the TI datasheet to confirm whether separate analog and digital supplies require distinct filtering. Select regulator dropout, transient response, and quiescent current based on the measurement load and the time the MCU spends in low-power modes.
Keep ADC inputs and communication traces away from noisy switching nodes and high-current return paths. Route decoupling connections with short, low-loop-area paths, and place external crystals, capacitors, and serial terminations according to the exact pin functions in the manufacturer datasheet. A 64-LQFP package requires careful fanout and thermal-via planning even though the MCU may operate at low average power.
Do not treat another MSP430F2xx TPM device as automatically interchangeable. Compare pin multiplexing, ADC channels, timer resources, communication peripherals, interrupt vectors, memory size, voltage limits, clock requirements, and package thermal details before substituting. The supplied alternative data does not provide a complete compatibility matrix, so firmware and hardware validation are mandatory.
