MSP430F478IPN - 16-Bit 8MHz Sensing MCU | Texas Instruments
料号： MSP430F478IPN ✓ 量产中MSP430F478IPN 概述
An MCU is an integrated circuit containing a processor core, memory, peripherals, and interfaces on one die. The MSP430F478 belongs to the mixed-signal microcontroller category within the broader embedded-controller and semiconductor hierarchy. Its sensing-oriented feature set allows a design to acquire analog measurements, process them in software, and present information through an LCD without requiring several separate discrete components.
Key features include an 8 MHz maximum clock, 48 KB of Flash program memory, 2 KB of RAM, one 16-bit Sigma-Delta ADC, one 12-bit DAC, support for a 128-segment LCD, and 48 I/O pins. The industrial temperature grade and 80-LQFP package make the device suitable for compact embedded products that require both digital control and analog measurement functions.
The MSP430 CPU16 architecture uses a 16-bit register-oriented design intended for low-power embedded control. Flash memory provides 48 KB for firmware, while 2 KB of RAM supports working data. The Sigma-Delta ADC is suited to measurement channels where integrated conversion is useful, and the 12-bit DAC provides an analog output for control or reference applications. The LCD controller can reduce the component count in segment-display designs.
Typical applications include industrial panel meters, portable environmental monitors, laboratory instruments, digital thermometers, data loggers, and compact control panels. These uses benefit from combining an ADC, DAC, LCD drive, and microcontroller in a single package while limiting board area and external component count.
Designers should verify the complete pin assignment, operating limits, ADC and DAC electrical characteristics, and recommended decoupling directly from the manufacturer datasheet before layout. The supplied verified data identifies the 80-LQFP package but does not provide a public pin-by-pin mapping, so this record does not infer one.
This page consolidates verified manufacturer and distributor information, current sourcing data, structured specification gaps, and practical application guidance. It also distinguishes documented facts from unavailable pin-level, pricing-tier, and drop-in replacement data so engineers can make sourcing and design decisions without unsupported assumptions.

典型应用
MSP430F478IPN 适用于 6 应用s: Industrial Panel Meter, Portable Environmental Monitor, Digital Thermometer, Laboratory Data Logger, Digital Control Panel, Low-Power Sensing Node.
Industrial Panel Meter
The MSP430F478IPN fits an industrial panel meter because it combines a 16-bit Sigma-Delta ADC, a 128-segment LCD controller, and an 8 MHz MCU in one 80-LQFP package. The ADC can acquire a sensor signal, while the MCU processes the reading and the LCD controller drives the local display without a separate display controller. The 48 KB of Flash provides room for calibration, filtering, and interface firmware. Before layout, engineers should confirm the ADC input range, sample rate, LCD segment mapping, and supply operating range because those numerical details are not present in the supplied verified data.
推荐
Portable Environmental Monitor
The MSP430F478IPN can support a portable environmental monitor by combining measurement, control, and local presentation in a single MCU. Its one 16-bit Sigma-Delta ADC is suited to sensor conditioning, the 2 KB RAM supports working data, and the 48 KB Flash can store sampling, filtering, and calibration routines. A 128-segment LCD provides a low-power local display option for temperature, humidity, or air-quality readings. Because no numerical low-power current or operating-voltage data was supplied, battery-life calculations and regulator selection must use the manufacturer datasheet rather than assumptions.
推荐
Digital Thermometer
The MSP430F478IPN is suitable for a digital thermometer that requires analog measurement and a segmented local display. The integrated 16-bit Sigma-Delta ADC can acquire the output of a temperature-sensing front end, while the 8 MHz CPU16 core performs conversion, averaging, offset correction, and display formatting. The 12-bit DAC may also support test, bias, or reference functions when the application requires an analog output. The 80-LQFP footprint provides 48 documented I/O pins for sensor inputs, buttons, and display connections, although exact pin assignments must be verified from the manufacturer datasheet.
推荐
Laboratory Data Logger
The MSP430F478IPN can serve as the control core of a laboratory data logger that records slow-moving analog measurements and presents status locally. The 16-bit Sigma-Delta ADC supports precision-oriented measurement channels, the 48 KB Flash stores firmware and buffering parameters, and the 2 KB RAM provides space for working variables and short-term records. Its LCD support can reduce the need for a separate display controller in compact instruments. The final design must verify ADC input bandwidth, sampling rate, memory limits, and communications interfaces from the complete MSP430F47x datasheet before committing to the architecture.
推荐
Digital Control Panel
The MSP430F478IPN aligns with digital control panels because its LCD controller can drive up to 128 segments, its 48 I/O pins can connect switches and indicators, and its integrated analog resources can supervise process values. The 8 MHz MSP430 CPU16 core handles user-interface state, alarms, configuration, and control logic. The 12-bit DAC offers an analog control output for slow system functions, while Flash accommodates panel configuration and diagnostic routines. Package routing, LCD glass compatibility, pin multiplexing, and electrical limits should be confirmed against the TI datasheet because those details are not included in the retrieved source excerpts.
推荐
Low-Power Sensing Node
The MSP430F478IPN fits a low-power sensing node that needs measurement, local processing, and limited user-interface capability in one package. Its integrated 16-bit Sigma-Delta ADC minimizes the need for a separate converter, the 48 KB Flash supports compact embedded firmware, and the 2 KB RAM supports active working data. The LCD interface can provide local status on low-power handheld or field-service equipment without continuously driving a graphical display. Actual sleep current, wake-up time, and allowable voltage range remain undocumented in the supplied snippets, so battery sizing and power architecture require direct consultation of the manufacturer datasheet.

设计说明
Do not treat related MSP430F47x devices as automatic drop-in replacements. MSP430F478IPN is documented in an 80-LQFP package, while the comparison results identify alternatives using different package designations. Before a redesign, verify every physical pin, power pin, ADC input, DAC output, LCD segment, and debug connection against the manufacturer datasheet. A functional equivalence in clock speed or memory does not establish PCB-level compatibility.
Build the power budget from the exact operating mode, supply voltage, and peripheral configuration listed in the manufacturer datasheet. The retrieved sources establish that this is an ultra-low-power MSP430 sensing MCU, but they do not provide numerical active or sleep currents. Do not estimate battery life from the 8 MHz maximum clock alone. Confirm the ADC, DAC, LCD, and oscillator load at each operating point, then size the supply and decoupling network from those verified limits.
The 80-LQFP footprint provides dense routing for the 48 documented I/O pins and analog, LCD, and debug functions. Place analog input routing away from LCD drive traces and switching nodes, and follow the datasheet's recommended grounding and decoupling topology. Because no verified land pattern or pin map appears in the supplied data, use the current TI package drawing and pinout rather than scaling or adapting another MSP430 board layout by inspection.
The Sigma-Delta ADC should be connected to a front end whose source impedance, bandwidth, and filtering are compatible with the device's documented input characteristics. Those numerical limits are unavailable in the retrieved snippets, so they must be obtained from the MSP430F47x datasheet before defining the sensor network. Validate offset, gain, noise, and conversion timing in hardware, and isolate LCD drive activity if it appears in the measured analog signal.
合规信息
The supplied verified excerpts identify an industrial temperature grade but do not explicitly provide RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals declarations. These fields remain unknown rather than being inferred.
