MSP430F1611IPM - 8MHz 16-bit Mixed-Signal MCU | Texas Instruments
部品番号: MSP430F1611IPM ✓ 生産中MSP430F1611IPM 概要
A mixed-signal microcontroller combines a digital processor with analog conversion and interface functions on one device. The MSP430 belongs to the microcontroller and embedded-processor hierarchy rather than a general-purpose processor class. Its 16-bit RISC core uses 16-bit registers and constant generators, while integrated analog peripherals reduce the need for external converters and interface components in compact industrial and instrumentation designs.
Core features include 8 MHz maximum clock speed, 48 KB Flash for firmware, 10 KB SRAM for working data, and 22 I/O ports. The analog subsystem includes a 12-bit ADC, two 12-bit DAC channels, and a comparator. Peripheral integration covers DMA, I2C, SPI, and UART, enabling the MCU to connect sensors, displays, memories, converters, and host processors. I2C support includes standard mode up to 100 kbps and fast mode up to 400 kbps.
Power efficiency is a defining MSP430 characteristic. The device consumes 330 µA in active mode at 1 MHz and 2.2 V, draws 1.1 µA in standby mode, and reaches 0.2 µA in off mode with RAM retention. It also provides five power-saving modes and wakes from standby in less than 6 µs. These figures make deterministic, battery-influenced operation practical when the design alternates between measurement activity and long low-power intervals.
Typical applications include industrial sensor acquisition, low-power instrumentation, portable measurement equipment, embedded data loggers, and compact control systems with analog outputs. The ADC supports analog measurement, while the dual DAC supports control signals, test excitation, or output-voltage setpoints. UART, SPI, I2C, and DMA provide flexible paths for external sensors, storage devices, and communication links.
PCB design should preserve a quiet analog supply path, place decoupling capacitors close to the supply pins, and route analog inputs away from high-current switching nodes. Verify the complete pin description in the manufacturer datasheet before assigning board functions. The 64-LQFP footprint also requires adequate solder-mask and thermal relief around the perimeter pads.

主な用途
MSP430F1611IPM の用途: 6 件s: Industrial Sensor Acquisition, Low-Power Data Logger, Portable Measurement Instrument, Analog Control and Signal Generation, Communication Gateway, Battery-Powered IoT Node.
Industrial Sensor Acquisition
The MSP430F1611IPM suits industrial sensor modules that require local 12-bit conversion, low standby consumption, and flexible communications. Its 48 KB Flash can hold acquisition control, filtering, diagnostics, and calibration routines, while 10 KB SRAM supports working buffers and sensor fusion. The 330 µA active current at 1 MHz and 2.2 V supports repeated measurements, while the less-than-6 µs standby wake-up allows the controller to remain responsive between polls. Use I2C for compatible sensors, SPI for higher-rate converters, and UART for reporting results to a host controller.
おすすめ
Low-Power Data Logger
The MSP430F1611IPM is appropriate for periodic data logging because it combines 48 KB Flash with a standby current of 1.1 µA and an off-mode current of 0.2 µA with RAM retention. The MCU can wake, measure through the 12-bit ADC, store information in Flash, and return to a low-power state without frequent processor activity. Its five power-saving modes help separate active acquisition from idle intervals, and the integrated comparator can detect thresholds without continuous software polling. For long deployments, choose a suitable nonvolatile storage strategy and confirm write endurance for the expected logging cycle.
おすすめ
Portable Measurement Instrument
The MSP430F1611IPM fits portable measurement equipment that combines analog input conditioning with digital computation and limited power availability. Its 8 MHz 16-bit RISC core can process measurement results, the 12-bit ADC acquires the primary analog channel, and the dual 12-bit DAC can generate reference or control voltages. The 1.8 V minimum operating voltage supports low-voltage product architectures, while standby and RAM-retention modes preserve state between interactions. UART or USB-interface circuitry can expose results to a host, but the board must include the required level conversion and protection for external connections.
おすすめ
Analog Control and Signal Generation
The MSP430F1611IPM is well suited to closed-loop control tasks that require measured inputs and programmable outputs on one microcontroller. The 12-bit ADC provides the feedback path, the dual 12-bit DAC channels provide two independently controlled analog outputs, and the comparator can provide fast threshold information. Firmware running on the 16-bit RISC core can implement filtering, proportional-integral-derivative control, limit detection, and fault handling. I2C and SPI expand the design with external sensors or converters, while DMA can transfer peripheral data with less CPU intervention. Validate loop timing and output settling against the target system dynamics.
おすすめ
Communication Gateway
The MSP430F1611IPM can serve as a compact gateway between local sensors and a higher-level controller because it combines I2C, SPI, UART, and DMA in a low-power package. I2C supports standard operation up to 100 kbps and fast operation up to 400 kbps, while SPI accommodates faster peripherals and UART provides a straightforward host interface. The 48 KB Flash is sufficient for protocol handling and buffering logic, and 10 KB SRAM supports message queues and packet assembly. Use DMA for predictable peripheral transfers, define protocol timeouts, and ensure the chosen interface voltage levels match the external devices.
おすすめ
Battery-Powered IoT Node
The MSP430F1611IPM can serve as the control hub in a battery-powered IoT node that combines sensing, local logic, and low-rate communications. The 16-bit processor provides enough arithmetic capacity for preprocessing, while the 12-bit ADC supports sensor digitization and the dual DAC can drive low-power analog interfaces. Standby current of 1.1 µA and wake-up in less than 6 µs help reduce the time the node spends awake, although the complete energy budget also depends on sensors and radios. Use UART or SPI for attached modules and activate the radio only after local measurements are ready.

設計ノート
Place the required supply bypass capacitors adjacent to the MSP430F1611IPM power pins and connect them with short, low-inductance traces. Separate analog and digital return paths as far as practical, especially around ADC and DAC circuits. Route analog inputs away from UART, switching-supply, and high-current outputs to reduce coupling into the 12-bit conversion results.
Do not treat a shared package name as proof of complete electrical interchangeability. Before replacing the MSP430F1611IPM with MSP430F1613IPM or MSP430F1491IPMG4, compare every assigned pin, supply requirement, clock configuration, memory requirement, ADC input, DAC output, DMA channel, and interrupt vector. Confirm that the replacement's software driver and development project support the selected device.
Design the power tree around the 1.8 V to 3.6 V operating range and include enough source current for the processor, analog circuitry, external sensors, and communication interfaces. The 330 µA figure applies to active operation at 1 MHz and 2.2 V and does not include external loads. Use regulator dropout margin, transient response, and startup sequencing appropriate for the complete system.
Keep the 64-pin LQFP footprint within the manufacturer's recommended land pattern and verify pin-one orientation against the package drawing. A 10 mm by 10 mm body requires adequate routing channels for power, ground, analog signals, and serial interfaces. Use vias sparingly beneath fine-pitch devices where process capability is uncertain, and follow the current assembly and land-pattern guidance for the production facility.
Treat analog reference and DAC outputs as sensitive signal paths: use short traces, solid ground references, and separate return paths from digital switching activity. If the ADC samples a high-impedance source, provide suitable settling time and acquisition support according to the manufacturer's guidance. Calibrate offset and gain at the final operating voltage because regulator and reference tolerances can shift the measurement scale.
コンプライアンス情報
The manufacturer lists the MSP430F1611 as an active mixed-signal microcontroller. RoHS, REACH, lead-free, halogen-free, conflict-minerals, and automotive-qualification status require confirmation in the current product compliance documentation.
