MSP430F133IPAG - 16-Bit 8MHz Ultra-Low-Power MCU | Texas Instruments
部品番号: MSP430F133IPAG ✓ 生産中MSP430F133IPAG 概要
An ultra-low-power microcontroller is an integrated circuit designed to execute embedded-control tasks while minimizing energy consumption between measurement and processing events. The MSP430 architecture belongs to the embedded microcontroller and mixed-signal IC hierarchy. Its 16-bit RISC core, 16-bit registers, constant generators, and five low-power operating modes make it suitable for instruments, meters, sensors, and portable measurement systems that spend much of their service life in standby or RAM-retention states.
The device's principal features include an 8 MHz maximum clock, 8 KB of Flash program memory, 256 bytes of SRAM, a 12-bit ADC, a comparator, and serial interfaces for SPI and UART. A 1.8 V to 3.6 V supply-voltage range supports low-voltage system designs, while the mixed-signal peripherals allow analog sensing and digital control to share one device. Wake-up from standby occurs in less than 1 µs, reducing the latency penalty associated with duty-cycled operation.
The MSP430 CPU16 core uses a compact 16-bit RISC architecture with 16-bit registers and constant generators. Its reduced instruction set supports efficient control-code execution, while the hardware ADC and comparator reduce the need for separate analog front-end ICs. Active-mode current is characterized at 1 MHz and 2.2 V, and the device supports multiple power-saving modes for embedded systems operating from restricted energy budgets.
Typical applications include low-cost data loggers, industrial panel meters, battery-powered monitors, portable test equipment, environmental sensors, and compact control modules. The TQFP-64 package provides enough I/O and analog resources for designs that require multiple inputs, external memory interfaces, or several serial peripherals while avoiding the size constraints of smaller packages.
When laying out the board, treat analog and digital return paths as separate networks until they meet at the device ground reference. Place input and bypass capacitors close to their pins, follow the datasheet grounding topology, and confirm the operating voltage before programming external peripherals. Use the manufacturer datasheet pin table and recommended application schematic for final net assignments and decoupling values.
This page combines device specifications, package details, application guidance, comparison parameters, and same-family replacement options to support component selection and board-level implementation. It also organizes practical low-power and mixed-signal design considerations that are not presented together in a standard distributor listing.

主な用途
MSP430F133IPAG の用途: 6 件s: Battery-Powered Environmental Sensor, Industrial Panel Meter, Portable Data Logger, Low-Cost Test and Measurement Instrument, Motor Control and Feedback Interface, Remote Sensor and Telemetry Node.
Battery-Powered Environmental Sensor
The MSP430F133IPAG fits battery-powered environmental sensing because its 1.8 V to 3.6 V supply range supports low-voltage cells and regulated 3.3 V rails. The integrated 12-bit ADC can digitize temperature, humidity, or gas-sensor outputs without a separate converter. Its five low-power modes, 0.1 µA off-mode current with RAM retention, and less-than-1-µs standby wake-up support duty-cycled sampling. A practical design measures the analog channel, averages readings in the 256-byte SRAM, transmits over SPI or UART, and then returns to a low-power state until the next interval.
おすすめ
Industrial Panel Meter
The MSP430F133IPAG supports compact panel meters that combine analog measurement, local processing, and serial data output. Its 12-bit ADC supplies sufficient resolution for many voltage, current, and temperature sensors, while the comparator supports threshold detection and signal conditioning. The 22 I/O ports allow display keys, status indicators, and serial communications to share one controller. At an 8 MHz maximum clock, the device can service measurement tasks and communication protocols, while standby modes reduce consumption between operator interactions or remote polling events.
おすすめ
Portable Data Logger
The MSP430F133IPAG is appropriate for portable data loggers that periodically capture sensor data and preserve operating state between samples. The 8 KB Flash stores firmware and configuration parameters, and the 256-byte SRAM holds working buffers during acquisition. SPI or UART can connect the MCU to an external memory device or wireless module. Duty-cycling the acquisition loop allows the controller to wake in less than 1 µs, collect a sample, append data, and return to standby, reducing energy use compared with continuous operation.
おすすめ
Low-Cost Test and Measurement Instrument
The MSP430F133IPAG can serve as the control core of a low-cost handheld measurement instrument with analog inputs and a serial host interface. The 12-bit ADC and comparator permit direct sensing of slow or threshold-based signals, while the 8 MHz RISC core handles timing, calibration, and data formatting. Its 1.8 V to 3.6 V operating range simplifies design partitioning around low-voltage sensors and transceivers. The 64-pin TQFP package also provides sufficient routing flexibility for multiple digital inputs, outputs, and debug or programming connections.
おすすめ
Motor Control and Feedback Interface
The MSP430F133IPAG can manage feedback, monitoring, and supervisory functions in a motor-control subsystem where a dedicated control IC is not required. The comparator and 12-bit ADC can monitor position, current-sense, or feedback signals, while 22 I/O ports handle limit switches, direction signaling, and status reporting. The SPI or UART interface allows the controller to exchange data with a higher-level processor. Low-power modes are useful in systems that remain active only for periodic position checks, although motor timing requirements must be verified against the device's specified operating conditions.
おすすめ
Remote Sensor and Telemetry Node
The MSP430F133IPAG fits remote telemetry nodes that acquire local measurements and forward results through a serial link. Its low-voltage operation, five power-saving modes, and rapid standby wake-up allow the radio or modem to remain disabled for most of the duty cycle. The 12-bit ADC handles sensor conditioning directly, and the 22 I/O ports provide status and configuration signals. Firmware can alternate between acquisition, packet preparation, and transmission states, while off mode with RAM retention helps preserve counters, configuration values, and partial results between wake-up events.

設計ノート
Configure the device around its intended duty cycle rather than treating the 8 MHz maximum clock as a continuous operating requirement. Use standby or off mode with RAM retention between acquisition events, keep analog peripherals disabled when not required, and verify that the wake-up interval meets the measurement schedule. Confirm the resulting average current at the system level, including sensor and communication-module leakage.
Place decoupling capacitors at the device power pins using the topology and capacitance specified in the manufacturer datasheet, and keep each capacitor connection to the package pin as short as practical. Route analog inputs away from switching nodes and high-current return paths. A solid ground plane under the device improves return-path continuity, but analog-signal ground and digital-switching current should be arranged according to the recommended application layout.
Treat analog inputs as potentially high-impedance nodes until the source impedance is known. Keep traces short, place the source close to the ADC or comparator input, and avoid routing them beside UART, SPI, or clock signals. If the sensor output can float during power transitions, add the input-conditioning network recommended by the sensor manufacturer so the MCU does not consume excess current or process an undefined voltage.
Do not assume that a same-package family member is firmware-compatible without checking its memory map, port multiplexing, interrupt-vector layout, and peripheral set. The MSP430F133IPAG has 8 KB of Flash and 256 bytes of SRAM, so code that depends on the larger memory of the MSP430F135IPAG requires additional review. After any substitution, rebuild for the target device and retest analog accuracy, serial timing, and low-power behavior.
