MSP430A064IPM - 16-Bit 8MHz MCU with 48KB Flash | TI
部品番号: MSP430A064IPM ✓ 生産中MSP430A064IPM 概要
An MSP430 microcontroller is a mixed-signal embedded-processing device designed to measure, control, and communicate while operating with low energy consumption. The MSP430 architecture integrates a 16-bit RISC core, analog conversion, timing, serial communication, and GPIO resources on one chip. Within the broader semiconductor hierarchy, it is a microcontroller, embedded processor, and mixed-signal IC intended to replace combinations of discrete analog and digital components in compact embedded systems.
The MSP430A064IPM provides 48 KB of flash for firmware, 2 KB of RAM for working data, and an 8 MHz maximum operating frequency. Its 12-bit ADC supports embedded measurement functions, while two USARTs provide serial communication channels for sensors, external converters, programming equipment, or data acquisition systems. The hardware multiplier supports efficient multiplication in control and signal-processing routines, and the 64-LQFP package exposes a broad set of I/O and peripheral connections.
The part is identified for industrial-temperature operation from -40°C to +85°C and operates from 2.2 V to 3.3 V according to the product listing information. A 64-pin gull-wing LQFP package supports conventional surface-mount assembly while providing more external pins than smaller MSP430 packages. The combination of flash memory, RAM, ADC channels, serial interfaces, and a maximum 8 MHz clock makes the device suitable for compact control systems that need local sensing and communications without a higher-power processor.
Typical applications include industrial sensor nodes, low-power data loggers, building automation endpoints, battery-operated measurement instruments, motor and process control, and embedded communications equipment. The two USARTs can manage multiple serial links, while the ADC can acquire analogue sensor inputs without requiring a separate converter. Software should budget memory carefully because the 48 KB flash and 2 KB RAM are sufficient for focused control tasks rather than demanding graphical interfaces or large data buffers.
Design the PCB with short analogue input routes, adequate bypassing at the power pins, and careful grounding around the ADC. Confirm the exact pin functions and multiplexing constraints against the manufacturer pin description before assigning signals. Programme the device with a toolchain compatible with the MSP430 architecture, and validate clock, analogue, serial, and low-power settings across the intended temperature range.
This page organizes the verified technical characteristics, pin-package details, sourcing information, drop-in alternatives, comparison parameters, and practical design guidance for engineers evaluating the MSP430A064IPM. It also distinguishes exact ordering information from broader MSP430 family options, helping designers assess PCB reuse, firmware portability, peripheral requirements, and supply continuity before committing a design.

主な用途
MSP430A064IPM の用途: 6 件s: Industrial Sensor and Condition Monitoring, Battery-Powered Data Logger, Building Automation Endpoint, Low-Power Communications Controller, Process and Motor Control, Portable Measurement Instrument.
Industrial Sensor and Condition Monitoring
The MSP430A064IPM fits compact industrial monitoring systems that must acquire analogue sensor data and operate locally without a higher-power processor. Its 12-bit ADC provides a dedicated conversion interface, while 48 KB of flash gives application firmware room for sampling control, filtering, calibration, event handling, and serial protocols. Two USARTs allow one interface to serve a sensor or transceiver while another supports diagnostics or configuration. The -40°C to +85°C industrial temperature range supports equipment deployed beyond room-temperature environments. Use the 8 MHz maximum clock for time-based sampling and control tasks, and reserve the 2 KB RAM for bounded buffers rather than large historical datasets.
おすすめ
Battery-Powered Data Logger
The MSP430A064IPM is appropriate for battery-powered data loggers that need local processing but must balance memory capacity and energy use. Its 48 KB of flash provides nonvolatile storage for firmware and compact parameter sets, while the 2 KB RAM supports short acquisition windows and protocol buffers. The 2.2 V to 3.3 V operating range accommodates low-energy supply designs, and the 12-bit ADC can digitize temperature, pressure, or level inputs. Two USARTs can connect an external radio or memory device and provide a diagnostic channel. The principal design constraint is RAM: use the on-chip flash for larger histories and design firmware to avoid simultaneous tasks that exceed the 2 KB working-memory limit.
おすすめ
Building Automation Endpoint
The MSP430A064IPM can serve as the local controller in a building-automation endpoint where the device must read environmental inputs, control outputs, and communicate over a serial network. The 12-bit ADC supports basic temperature, illumination, or occupancy-sensor conditioning, while two USARTs offer flexible connectivity to a bus transceiver or service interface. With 48 KB of flash and 2 KB of RAM, the part fits compact gateway logic, scheduled control routines, and event processing. Its industrial temperature range suits equipment rooms and controlled enclosures. Care should be taken with power-supply rejection and analogue grounding because a shared communications connector can introduce noise into low-level sensor measurements.
おすすめ
Low-Power Communications Controller
The MSP430A064IPM is useful as a protocol and control controller beside a wireless or wired communications module. Two USARTs permit simultaneous communication and debug traffic, while the 16-bit RISC core and hardware multiplier can process framing, checksums, and protocol state at up to 8 MHz. The 48 KB flash capacity accommodates networking stacks or command handlers that are too large for the smallest MSP430x1xx members, and the 2 KB RAM is suitable for transmit and receive buffers of moderate size. When using the device near a radio, isolate analogue and digital return paths and validate clock tolerance against the communications link before production release.
おすすめ
Process and Motor Control
The MSP430A064IPM fits compact process-control and motor-control modules where deterministic local logic, analogue feedback, and serial adjustment are required. The hardware multiplier supports efficient arithmetic in control calculations, the 12-bit ADC can acquire command or feedback signals, and two USARTs can connect to a tuning interface or upstream controller. At an 8 MHz maximum clock, the MSP430 family architecture supports responsive supervisory control while keeping the design focused. The 48 KB flash accommodates control code and parameter tables, but the 2 KB RAM requires bounded loop variables and carefully sized buffers. Power-stage design and protection remain separate concerns and should use appropriately rated external components.
おすすめ
Portable Measurement Instrument
The MSP430A064IPM can act as the control and communications processor in a portable measurement instrument powered from a rechargeable battery. The 12-bit ADC handles basic analogue measurements, the two USARTs support a display, host computer, or calibration interface, and the 48 KB flash provides enough code space for measurement sequencing, scaling, calibration coefficients, and command handling. Its 2.2 V to 3.3 V operating range supports compact low-voltage architectures, while the industrial temperature rating broadens the usable environmental range. Use low-leakage analogue paths and stable references because measurement accuracy depends on the complete signal chain, not only the microcontroller's converter resolution.

設計ノート
Design the MSP430A064IPM supply for its documented 2.2 V to 3.3 V operating range, including startup and transient margins. Place the required bypass capacitance close to the device's supply terminals and keep the return path short to reduce supply-impedance interaction with the ADC and switching peripherals. Confirm the exact VDD and decoupling requirements in the manufacturer datasheet before finalising component values or rail topology.
Route analogue inputs away from high-current digital and communications paths, and use a continuous ground reference beneath the MCU where the package and board construction permit. Keep ADC traces short, avoid crossing them with switching-node routes, and place analogue bypass components near their intended pins. The 12-bit converter can be affected by impedance, ripple, and ground noise even when firmware sampling is correctly configured.
Do not treat a shared LQFP footprint as proof that every alternative is functionally interchangeable. Check alternate pin functions, interrupt assignments, analogue-channel locations, USART routing, clock settings, and device-specific electrical limits. For MSP430A055IPM and MSP430A054IPM, also verify that the existing firmware fits within 16 KB or 8 KB of flash and that no code depends on target-only peripherals or memory regions.
Plan programming, test, and debug access before placing the 64-pin LQFP. A small footprint can make exposed programming contacts and debugging launches inconvenient, while dense routing around the gull-wing leads can reduce assembly access. Use a package-aware land pattern from the manufacturer drawings, maintain adequate solder-mask and paste control, and verify connector orientation against the pin-1 indicator on the PCB and package.
