MSP430F479IPN - 8MHz 16-Bit Sensing MCU | Texas Instruments
부품 번호: MSP430F479IPN ✓ 활성MSP430F479IPN 개요
A microcontroller is a programmable semiconductor that executes application software, reads sensors, controls peripherals, and interfaces with a wider electronic system. The MSP430 belongs to the ultra-low-power MCU hierarchy, combining a 16-bit RISC core with mixed-signal peripherals. The MSP430F479 targets instrument, meter, sensor-node, and human-interface applications where measured signals must be converted, displayed, and processed locally.
Principal features include 60 KB of program flash configured as 60K × 8 bytes plus 256 bytes, 2 KB of RAM, and 48 I/O pins. Its analog subsystem includes one 16-bit Sigma-Delta ADC and a 12-bit DAC. The integrated 128-segment LCD controller reduces external display-driver requirements, while the 8 MHz CPU supports responsive control and measurement processing. The device operates from -40°C to +85°C and is supplied in an LQFP package with 80 pins.
The MSP430 architecture is designed around low-power operation, making the MCU suitable for battery-operated instruments and embedded sensing systems. Analog conversion, LCD multiplexing, general-purpose I/O, and serial communications are integrated around the same CPU. This consolidation can reduce board area and simplify firmware when compared with a system assembled from separate microcontroller, ADC, DAC, and LCD-controller devices.
Typical uses include industrial panel meters, portable environmental monitors, laboratory instruments, programmable logic controllers, medical monitoring equipment, and energy-metering products. The LCD controller suits products with segment displays, while the Sigma-Delta ADC supports high-resolution measurement of slowly varying or differential sensor signals.
Design around the exact pin assignments, analog input limits, LCD segment mapping, and peripheral multiplexing documented in the Texas Instruments datasheet. Keep analog and LCD routing separated from sensitive timing paths, and verify the external-component values required by the selected reference circuit.
This product page combines manufacturer specifications, package details, sourcing guidance, design considerations, and verified drop-in candidates. It also identifies where firmware, board-layout, and qualification checks remain necessary before an MSP430F479IPN is released into production equipment.

일반적인 애플리케이션
MSP430F479IPN 적합 용도: 6 애플리케이션s: Industrial Panel Meter, Portable Environmental Sensor, Programmable Logic Controller, Medical Monitoring Equipment, Laboratory Data Acquisition, Energy Metering Instrument.
Industrial Panel Meter
The MSP430F479IPN fits industrial panel meters because it combines an 8 MHz 16-bit RISC core, a 16-bit Sigma-Delta ADC, and a 128-segment LCD controller in one 80-pin LQFP device. A sensor signal can be sampled, converted, filtered, and displayed without requiring a separate LCD-driver IC. The 48 I/O pins support keys, status indicators, alarm outputs, and communications. The main design consideration is the LCD segment map: assign pins and segment outputs from the datasheet tables, then verify contrast, bias, and glass requirements across temperature.
추천
Portable Environmental Sensor
The MSP430F479IPN supports portable environmental monitoring by combining low-power 16-bit RISC control with an integrated 16-bit Sigma-Delta ADC. It can digitize temperature, humidity, pressure, or gas-sensor outputs, apply calibration and filtering, and manage the measurement schedule. Its 2 KB RAM and 60 KB flash provide space for application code and operating parameters. Because battery life depends on duty cycle, calculate active and standby current from the datasheet operating-mode tables rather than assuming a single current value.
추천
Programmable Logic Controller
The MSP430F479IPN can serve as the control core of a compact programmable logic controller because its 48 I/O pins provide substantial digital interface capacity and the 8 MHz CPU supports responsive control logic. The 60 KB flash accommodates configuration tables and application firmware, while the 2 KB RAM supports state variables and communication buffers. The Sigma-Delta ADC can monitor analog process inputs, and the 12-bit DAC can generate a control reference. Validate input thresholds, isolation boundaries, output drive levels, and timing before connecting external loads.
추천
Medical Monitoring Equipment
The MSP430F479IPN is suitable for compact medical or wellness monitoring equipment that combines sensor acquisition, local processing, and a segment-display interface. Its 16-bit Sigma-Delta ADC supports measurements where low-frequency resolution is valuable, while the 8 MHz 16-bit core handles digital filtering and device control. The integrated 128-segment LCD controller can drive a simple clinical display without a separate display controller. Medical designs still require application-specific risk analysis, electrical isolation where applicable, validation of measurement accuracy, and compliance review for the finished instrument.
추천
Laboratory Data Acquisition
The MSP430F479IPN can form the local control and measurement section of a laboratory data-acquisition system. The 16-bit Sigma-Delta ADC is suited to precision conversion of suitable sensor signals, and the 12-bit DAC can supply stimulus or reference waveforms within its specified performance. Firmware can perform acquisition sequencing, calibration, digital filtering, and host communication. Confirm analog bandwidth, input range, reference stability, and settling behavior in the datasheet because the Sigma-Delta ADC should not be selected solely from its nominal resolution.
추천
Energy Metering Instrument
The MSP430F479IPN suits energy-metering instruments that need mixed-signal measurement, a local segmented display, and long-duration low-power operation. The 16-bit Sigma-Delta ADC can measure selected transducer outputs, the 12-bit DAC can support excitation or test functions, and the 128-segment LCD controller supports displays without an additional driver. The 60 KB flash and 2 KB RAM are appropriate for calibration coefficients, counters, and communications logic. Metering accuracy must be confirmed through the complete signal chain, including input protection, reference accuracy, filtering, and calibration.

주요 차별점
- Integrated analog and display resources (vs MSP430F479IPNR)
- Same 80-pin LQFP footprint for PCB reuse (vs MSP430F479IPNR)
- Purpose-built low-power sensing integration (vs General-purpose MCUs without integrated LCD and Sigma-Delta ADC)
설계 노트
Place the MCU, decoupling capacitors, crystal or timing components, and analog inputs according to the Texas Instruments datasheet reference layout. Keep the Sigma-Delta ADC input routing compact and away from LCD drive traces and switching nodes. The 80-pin LQFP footprint has fine-pitch leads, so inspect solder-joint filleting and lane geometry after assembly. Confirm that exposed programming and debugging signals are accessible without introducing long high-impedance nets.
Separate the 128-segment LCD outputs from sensitive analog inputs and clock signals, particularly when the display is updated continuously. Route ADC inputs away from LCD bias and segment-switching traces, use a quiet reference arrangement, and follow the datasheet grounding guidance for the analog and digital sections. If the application also uses high-current outputs, establish a return path that does not share sensitive analog ground segments. Validate noise and conversion performance with the final display and power-supply configuration.
Use the voltage range, decoupling, and power-sequence requirements specified in the manufacturer datasheet for the selected operating mode. Place bulk and high-frequency decoupling close to the appropriate supply pins and provide clean return paths for every capacitor. For battery-powered products, calculate average current from CPU active time, ADC duty cycle, LCD update rate, and standby duration. Do not use a nominal current figure without accounting for supply voltage, peripheral activity, and temperature.
Do not treat MSP430F479IPN and MSP430F479IPNR as different silicon devices; the meaningful difference is the orderable tray versus tape-and-reel format. Verify that the PCB footprint is the 80-pin LQFP (PN) pattern and that all multiplexed functions are assigned consistently in firmware. Also avoid assigning the 16-bit Sigma-Delta ADC or LCD controller solely from their headline resolutions; check input range, sampling behavior, segment count, and application bandwidth in the datasheet.
