MSP430F425IPM - 8MHz 16-bit MCU with 3 Sigma-Delta ADCs | Texas Instruments
MPN: MSP430F425IPM ✓ ActiveMSP430F425IPM Overview
A microcontroller is a programmable semiconductor that integrates a CPU, memory, and peripherals into one device. The MSP430 family is designed for portable measurement, industrial sensing, instrumentation, and battery-powered equipment where energy efficiency is important. MSP430F425IPM combines general-purpose digital control with dedicated analog conversion and LCD support, reducing the number of external components required in a typical measurement product.
The MSP430F425IPM provides an 8 MHz maximum clock speed and five power-saving modes. The manufacturer lists active-mode current as 400 uA at 1 MHz and 3 V, standby current as 1.6 uA, and off-mode current with RAM retention as 0.1 uA. Its three Sigma-Delta ADCs are intended for sensors with relatively slow or high-resolution analog outputs, while the LCD driver can support segmented display applications without a separate display controller.
The device includes 16 KB of Flash memory, described in distributor listings as 16K x 8 plus 256 bytes, and 512 bytes of RAM. Its 48 I/O ports provide flexibility for digital inputs, outputs, communication lines, and control signals. The 64-LQFP package is suitable for board-level designs that need broad I/O access and a conventional leaded package rather than a very small surface-mount footprint.
Typical applications include precision sensor interfaces, industrial measurement instruments, portable data loggers, handheld test equipment, energy-monitoring products, and LCD-equipped control panels. The low-power architecture is particularly useful when the instrument spends most of its operating time between measurements. Engineers should select external passives and communication peripherals to match the required sensor bandwidth, display characteristics, and communication protocol.
When laying out the circuit, place the MCU power pins, decoupling capacitors, analog reference connections, and LCD outputs according to the manufacturer pin-description and layout guidance. Keep sensitive analog and display traces away from high-current switching paths where practical. The MSP430F425IPM is identified as an active industrial-range device, making it suitable for designs that require low-power operation and integrated mixed-signal measurement functions.
This product page combines the manufacturer device information, distributor package and ordering details, and application-focused design guidance.

Typical Applications
MSP430F425IPM is suitable for 6 applications: Industrial Sensor Measurement, Portable Data Logger, LCD-Equipped Control Panel, Precision Test and Measurement, Energy and Power Monitoring, IoT Sensor Node.
Industrial Sensor Measurement
The MSP430F425IPM fits industrial sensor measurement products that need several low-rate analog channels and digital control in one package. Its three 16-bit Sigma-Delta ADCs provide dedicated conversion resources, while the 8 MHz MSP430 CPU16 handles configuration, filtering, and system control. The 48 I/O ports can connect sensors, status indicators, and actuators, while the 1.8 V to 3.6 V supply range supports compact embedded instruments. The 64-LQFP package also provides generous routing access compared with a very small leadless package.
Recommended
Portable Data Logger
The MSP430F425IPM is appropriate for portable data loggers because its low-power modes support duty-cycled operation between sample intervals. Three Sigma-Delta ADCs can acquire sensor information, the 512 bytes of RAM provide working storage, and 16 KB of Flash holds firmware and configuration data. The 16-bit CPU and 48 I/O ports support storage-card control, status inputs, and user-interface signals. Designers should evaluate external nonvolatile memory and radio requirements because those functions are not specified for this MCU.
Recommended
LCD-Equipped Control Panel
The integrated 128-segment LCD capability makes the MSP430F425IPM useful in compact control panels and handheld measurement instruments. The MCU can operate the display while managing buttons, sensors, and system outputs through 48 I/O ports. Its standby current of 1.6 uA and off-mode current of 0.1 uA with RAM retention support energy-conscious interfaces. The exact LCD glass compatibility, segment count, bias arrangement, and drive timing must be checked in the manufacturer LCD-driver documentation.
Recommended
Precision Test and Measurement
The MSP430F425IPM supports portable test and measurement equipment that combines analog sensing with a user interface. Its three Sigma-Delta ADCs can serve temperature, pressure, or resistive sensor channels, while the CPU handles calibration values and measurement sequencing. The LCD driver reduces display-interface overhead, and the 48 I/O ports support range selection, trigger controls, and communication links. For high-bandwidth signals or instrumentation requiring greater flash memory, a different MCU architecture may be required.
Recommended
Energy and Power Monitoring
The MSP430F425IPM can serve as the control and measurement controller in energy-monitoring equipment that uses slower analog inputs and segmented displays. Its low-power operating modes are useful in meters and monitors designed for long standby periods, while the Sigma-Delta ADCs can sample voltage or current-sensor outputs. The 16-bit CPU supports calibration and compensation routines, and the LCD driver supports an integrated display. External isolation, sensor conditioning, and safety-rated components remain system-level requirements.
Recommended
IoT Sensor Node
The MSP430F425IPM is suitable for a local sensor-node controller when a wireless module or wired communications transceiver handles connectivity. Its low-power modes and Sigma-Delta ADCs support duty-cycled sensing, while 48 I/O ports provide digital sensor and status-control interfaces. Designers should reserve pins for the chosen radio, use the LCD driver only when required, and confirm memory sufficiency for protocol handling. The 64-LQFP package is practical when moderate I/O density is more valuable than minimal board area.

Design Notes
Place the required VDD decoupling capacitors close to the corresponding Texas Instruments MSP430F425 power pins and provide a clean return path for each supply connection. Use the manufacturer datasheet pin table to identify AVSS, VREF, and other analog-related connections; these nets should not be routed through switching-current paths. Verify the exposed thermal and power requirements for the 64-LQFP package during schematic and layout review.
Keep the three Sigma-Delta analog input routes short, symmetrical where practical, and isolated from LCD outputs, clock lines, and digital control signals. Confirm the input voltage range, source impedance, sampling behavior, and reference requirements from the MSP430F425 datasheet before selecting sensor or conditioning circuits. A slow sensor signal may still require filtering against board-level noise, so route analog grounds and return currents carefully.
Design the power budget around the specified operating modes: 400 uA active at 1 MHz and 3 V, 1.6 uA in standby, and 0.1 uA in off mode with RAM retention. Measure the actual application current because the listed active-mode figure is not a complete system consumption value and does not cover every peripheral or I/O condition. Select battery and regulator capacity for the longest expected measurement interval, including wake-up and sensor-settling intervals.
Do not assume that another MSP430 with a similar flash size is a drop-in replacement. The ADC count and resolution, LCD driver, I/O mapping, memory size, supply range, package dimensions, pin names, programming interface, and software device configuration must all match. Use the exact ordering suffix and review the Texas Instruments datasheet and pin-description table before modifying an existing PCB or releasing a substitute to production.
Compliance Information
The manufacturer product information identifies the MSP430F425 device as active and industrial-range. Specific RoHS, REACH, AEC-Q100, lead-free, halogen-free, and conflict-minerals declarations were not included in the product descriptions, so these fields remain unknown rather than being assumed.
