MSP430F167IPM - 16-Bit 8MHz Mixed-Signal MCU | Texas Instruments
부품 번호: MSP430F167IPM ✓ 활성MSP430F167IPM 개요
An MSP430 mixed-signal microcontroller combines a low-power RISC processor with analog peripherals on one integrated circuit. The MSP430 family uses a 16-bit RISC architecture and is designed for battery-powered, portable, industrial, and instrumentation products where energy efficiency, deterministic control, and compact mixed-signal integration are important. In the MSP430F167IPM, the analog and digital blocks are arranged to support sensor acquisition, control-loop monitoring, signal generation, and communications within one embedded platform.
The device's principal features include an 8 MHz maximum clock, 32 KB of Flash program memory, 1 KB of SRAM, a 12-bit analog-to-digital converter, and two 12-bit digital-to-analog converters. Its peripheral selection also includes a comparator, direct-memory-access support, I2C, SPI, and UART interfaces. These resources permit designers to consolidate functions that otherwise might require separate analog, communication, and processing components.
The MSP430 CPU16 uses 16-bit registers and a RISC instruction set designed for efficient embedded control. The integrated peripherals support concurrent acquisition, conversion, and communication tasks, while DMA can move data without requiring each byte to be processed by the CPU. The dual DACs are useful for excitation, reference, or control-signal generation, and the ADC provides direct quantization of analog inputs without a separate converter.
Typical uses include industrial sensor nodes, portable instrumentation, low-power data loggers, motor and process monitoring, and communications-enabled measurement equipment. For designs requiring multiple analog inputs, synchronized measurements, waveform generation, or low-power wake-up behavior, the combination of ADC, DAC, comparator, DMA, and serial interfaces reduces external component count and simplifies firmware design.
The most important layout consideration is preserving clean analog performance in a mixed-signal board. Place the MCU, analog supply bypass capacitors, reference components, and sensitive signal traces close together, while keeping switching-converter nodes and high-current paths away from the ADC inputs. Use the pin-description and recommended application-circuit information in the Texas Instruments MSP430F167 datasheet when assigning every LQFP-64 connection.
This page organizes the MSP430F167IPM's core specifications, application guidance, pin-package considerations, and same-footprint replacement options for faster engineering evaluation. It also distinguishes direct family alternatives from cross-brand substitutions so PCB changes, peripheral differences, and firmware requirements remain visible during component selection.

Portable Data Loggers
The MSP430F167IPM fits portable data-logging equipment that must acquire analog inputs while limiting energy use. According to the Texas Instruments MSP430F167 product page, the device combines an 8 MHz MSP430 CPU16 with 32 KB of Flash, 1 KB of SRAM, and a 12-bit ADC. DMA can transfer conversion data while firmware performs buffering and storage control, reducing processor intervention. The integrated dual 12-bit DACs can also generate calibration or test stimuli. Its standby wake-up time is specified as less than 6 µs, supporting designs that sleep between measurement intervals. For battery-powered deployments, calculate the complete energy budget from active current, standby current, sensor duty cycle, and retention requirements before selecting the final power architecture.

Industrial Sensor Acquisition
The MSP430F167IPM is appropriate for industrial sensor nodes that need local analog conversion and serial telemetry. Its 12-bit ADC, comparator, DMA, and 8 MHz CPU provide a compact path from sensor signal to digital processing without requiring a separate converter. According to the Texas Instruments MSP430F167 product page, I2C, SPI, and UART are available for connecting sensors and transmitting measurements. Place analog inputs away from switching nodes, use local bypass capacitance, and verify the input voltage and common-mode limits in the manufacturer datasheet. For factory equipment, also review operating temperature, supply regulation, isolation, and calibration requirements rather than treating the ADC resolution as the sole accuracy specification.
추천
Precision Test and Measurement
The MSP430F167IPM supports compact test and measurement instruments that need programmable analog excitation, monitoring, and communications. Its two 12-bit DACs can create reference or stimulus signals, while the 12-bit ADC can acquire the resulting response for closed-loop control. The 8 MHz MSP430 CPU16 provides deterministic control for instrument sequencing, and DMA can improve data-transfer efficiency. According to the Texas Instruments MSP430F167 product page, the device also includes a comparator for threshold and protection functions. Engineers should verify DAC settling behavior, ADC acquisition timing, reference accuracy, and analog noise in the datasheet, then include calibration and gain-error budget in the overall instrument accuracy calculation.
추천
Motor and Process Monitoring
The MSP430F167IPM can monitor analog process variables in compact motor-control or condition-monitoring equipment. The 12-bit ADC samples the selected sensor signal, while the comparator supports fast threshold detection, and the 8 MHz CPU executes supervisory control and fault handling. I2C and SPI provide links to external sensors, memory, or communication transceivers, and UART supports a simple host interface. DMA is useful when measurements must be transferred regularly without excessive CPU overhead. Place the MCU and analog input network away from motor drive nodes and high-current switching paths. Validate input bandwidth, grounding, supply disturbance, and isolation against the motor environment before approving the layout for production.

Communications-Enabled Sensor Hubs
The MSP430F167IPM fits small sensor hubs that consolidate measurements and communicate through embedded serial interfaces. The Texas Instruments MSP430F167 product page lists I2C, SPI, and UART, allowing the controller to connect local sensors, external memory, and a host or radio module. Its 32 KB of Flash provides embedded program storage, while 1 KB of SRAM supports short acquisition and protocol buffers. For a periodic-reporting design, use the less-than-6-µs standby wake-up specification when planning duty-cycle behavior and confirm the actual peripheral-state currents for the intended configuration. The PCB should keep sensor buses and radio or network interfaces separated from sensitive ADC traces to reduce coupling and ground-potential problems.
추천
Battery-Powered Portable Instruments
The MSP430F167IPM is well matched to battery-powered instruments that periodically measure, evaluate, and report data. Its low-power MSP430 architecture supports the standby and RAM-retention operating modes described by the manufacturer, while the 8 MHz CPU handles active measurement intervals. The 12-bit ADC, comparator, dual DACs, and DMA consolidate several functions into one controller and can reduce the number of discrete components. A successful design must account for the energy consumed by the ADC, DAC, serial interfaces, and external sensors in addition to MCU current. Validate battery-life estimates using worst-case temperature and operating conditions, and use the manufacturer power-mode table to confirm wake-up behavior and required state-retention settings.

설계 노트
Place the MSP430F167IPM close to the analog circuitry and provide local supply bypass capacitance at the device power pins. Route ADC inputs away from switching nodes and keep the ground-return path for analog signals continuous. The Texas Instruments MSP430F167 product page identifies both analog and digital resources in the same device, so PCB partitioning is important: separate the analog domain from clock, serial, and high-current outputs while maintaining a low-impedance common reference.
Use the manufacturer pin-description table when assigning the 64 LQFP connections, particularly analog inputs, DAC outputs, comparator inputs, reference pins, and supply rails. Check alternate-function multiplexing before connecting external circuitry because a peripheral signal may not be available on every package pin. For sensitive measurements, use short traces, guard structures where appropriate, and a quiet analog reference; otherwise the nominal 12-bit ADC resolution will not translate directly into system-level accuracy.
Calculate the active-mode energy budget from the selected clock frequency, operating mode, and required conversion or communications activity. The manufacturer lists a standby wake-up time of less than 6 µs and RAM-retention off current of 0.1 µA, but the complete system consumption also includes sensors, interface circuits, and leakage paths. For battery-powered products, test each duty-cycle state over the full temperature range because short active bursts can dominate average current even when standby consumption is low.
Do not assume that two LQFP-64 MSP430-family devices are interchangeable merely because their package drawings match. Confirm ADC channel count, DAC availability, comparator functions, DMA channels, serial-interface pin assignments, memory organization, clock configuration, interrupt vectors, and device identifiers in the manufacturer documentation. Also verify that the alternative's programming and development tools support the required firmware. A footprint match removes the need for a new land pattern, but it does not eliminate firmware or analog-schematic changes.
