MSP430G2553IPW8RQ1 - 16MHz Automotive MCU | Texas Instruments
部品番号: MSP430G2553IPW8RQ1 ✓ 生産中MSP430G2553IPW8RQ1 概要
An ultra-low-power microcontroller is a semiconductor device optimized to minimize energy consumption during active operation and standby. The MSP430 belongs to the embedded-controller hierarchy: microcontroller > mixed-signal MCU > ultra-low-power MCU. Its architecture combines a 16-bit RISC core with integrated analog and serial interfaces, reducing the component count required for embedded measurement, monitoring, and control designs.
The verified product information identifies a 16 MHz maximum clock, 16 KB Flash, 512 B SRAM, and 10-bit ADC. These resources suit applications that require periodic sensing, local control, and low-rate serial communication without adopting a higher-power application processor. Integrated UART, SPI, and I2C peripherals support sensor, actuator, display, and external peripheral connectivity while preserving a compact embedded design.
The MSP430G2553-Q1 product family targets automotive applications and is available in the specified 28-pin TSSOP configuration. Its MSP430 CPU16 architecture processes the ADC, comparator, timer, and communication resources in a compact package. The family-level information confirms the combination of 16 KB Flash and 512 B SRAM, making it suitable for firmware that coordinates mixed-signal sensing and embedded control rather than computationally intensive workloads.
Typical uses include automotive body-control modules, low-duty-cycle sensor nodes, battery-operated instrumentation, industrial condition-monitoring equipment, and compact communication controllers. The integrated serial interfaces allow a design to connect sensors over I2C or SPI, use UART for a local link, and employ the ADC for analog measurements while retaining the modest memory footprint of the MSP430 architecture.
Designers should verify the exact pin multiplexing, operating-voltage limits, clock configuration, and automotive qualification requirements in the manufacturer datasheet before layout release. The 28-pin TSSOP footprint also requires adequate spacing between fine-pitch leads, careful decoupling near the supply pins, and programming access consistent with the device configuration.
This page consolidates verified manufacturer and distributor information, automotive ordering details, practical application guidance, and honest replacement analysis. It distinguishes confirmed drop-in information from package-code or cross-family parts that cannot be treated as true pin-compatible substitutes.

主な用途
MSP430G2553IPW8RQ1 の用途: 6 件s: Automotive Body-Control Module, Battery-Operated Sensor Node, Industrial Condition Monitoring, Compact Communication Controller, Digital Thermometer and Data Logger, Embedded Data-Acquisition Unit.
Automotive Body-Control Module
The MSP430G2553IPW8RQ1 fits compact body-control modules because its 16 MHz CPU16 core combines 16 KB Flash and 512 B SRAM with an integrated 10-bit ADC, comparator, timer, UART, SPI, and I2C. A controller can sample an analog input, evaluate a threshold, drive a discrete actuator, and exchange diagnostic or configuration data through the serial peripherals. The 28-pin TSSOP package limits board area, while the automotive RQ1 ordering option supports qualification-oriented sourcing. Final deployment requires confirmation of the exact temperature grade, power behavior, transient requirements, and vehicle-specific validation.
おすすめ
Battery-Operated Sensor Node
MSP430G2553IPW8RQ1 is suitable for a battery-operated sensor node that periodically measures a slow-changing analog quantity and reports the result. Its 10-bit ADC and comparator can support threshold-based sensing, while 512 B SRAM provides working memory for short acquisition and processing routines. The 16 KB Flash budget can hold compact firmware, and the integrated UART, SPI, or I2C peripherals reduce the need for external communication components. Because average current depends on sleep duration, active time, and the selected external sensor, engineers should calculate the duty cycle against the manufacturer low-power specifications.
おすすめ
Industrial Condition Monitoring
The MSP430G2553IPW8RQ1 can act as the local controller in an industrial condition-monitoring module that combines analog measurement with serial sensor access. Its 10-bit ADC is appropriate for general-purpose trend and threshold monitoring, while the comparator supports fast discrete-level events without continuous software polling. UART, SPI, and I2C allow the same device to interface with external sensors, storage, or a host processor. The 16 MHz CPU16 core provides deterministic control timing, and the 28-pin TSSOP package supports compact instrumented equipment. EMC, isolation, calibration, and production-test requirements must be evaluated separately.
おすすめ
Compact Communication Controller
MSP430G2553IPW8RQ1 is well suited to a compact communication controller that must coordinate sensors and actuators across mixed serial buses. The integrated UART supports a local host or diagnostic connection, while SPI can accommodate higher-rate peripherals and I2C can connect to lower-speed devices. With 16 KB Flash, 512 B SRAM, a 16 MHz core, and an integrated ADC, the MCU provides local control alongside communication handling. The 28-pin TSSOP package reduces board area, but designers should confirm pin multiplexing and peripheral-instance assignments in the datasheet before assigning concurrent UART, SPI, and I2C functions.
おすすめ
Digital Thermometer and Data Logger
The MSP430G2553IPW8RQ1 can support a digital thermometer or compact data logger by combining its 10-bit ADC, timer, and serial interfaces. A sampled analog value can be converted, compared with thresholds, timestamped using a timer, and transmitted through UART, SPI, or I2C. Its 512 B SRAM supports short buffering tasks, while the ultra-low-power architecture is advantageous in devices expected to spend substantial time idle. Storage-medium selection and logging frequency determine whether 16 KB Flash and 512 B RAM are sufficient, so system-level memory sizing should precede schematic release.
おすすめ
Embedded Data-Acquisition Unit
MSP430G2553IPW8RQ1 fits a small embedded data-acquisition unit where an analog signal must be digitized and transferred through a compact mixed-signal controller. The 10-bit ADC handles general-purpose measurements, the comparator can support range or event detection, and the 16 MHz CPU16 core performs filtering and control. UART, SPI, and I2C provide flexible links to external converters, memory, or a host. Its 28-pin TSSOP package helps minimize PCB area, while 16 KB Flash and 512 B SRAM favor modest firmware workloads. ADC accuracy, reference quality, acquisition timing, and calibration method remain critical system-level constraints.

設計ノート
Confirm the complete 28-pin TSSOP pin map and package drawing from the current Texas Instruments datasheet before routing. The supplied sources identify the PW package and its 28 pins but do not provide the pin-by-pin names, so schematic and layout work must not rely on an inferred diagram. Place required decoupling capacitors close to their associated supply pins, keep the exposed thermal and programming access requirements visible, and use manufacturer land-pattern dimensions rather than generic TSSOP assumptions.
Estimate the average supply current from the active current, standby current, and application duty cycle rather than using the 16 MHz clock frequency as a proxy for power consumption. The verified data identifies the MCU as ultra-low-power but does not provide numerical current limits, so the missing electrical values must be obtained from the manufacturer datasheet. Validate startup behavior, analog-reference stability, and the transition between active and low-power modes with representative peripheral loads.
Assign analog, serial, and timer functions only after checking the datasheet’s multiplexed-pin matrix. The integrated ADC, comparator, UART, SPI, and I2C peripherals share a limited 28-pin package, and simultaneous use may change the available pin functions. Route sensitive analog inputs away from fast serial edges and switching-supply nodes, use a quiet analog reference arrangement, and keep programming-test access available for production programming and validation.
Do not treat MSP430G2553IPW20R as a replacement for the 28-pin MSP430G2553IPW8RQ1. The verified TI engineering discussion describes MSP430G2553IPW20R as a drop-in replacement for MSP430G2553IPW0RQ1, which uses a 20-pin TSSOP package. Likewise, do not substitute a different MSP430 family solely because it offers a similar clock or memory size; peripheral mappings, package pins, and firmware registers can differ even when headline specifications appear close.
