MSP430U275IPM - 64-LQFP 16-Bit Microcontroller | Texas Instruments
料号： MSP430U275IPM ✓ 量产中MSP430U275IPM 概述
A microcontroller is a programmable semiconductor that integrates a processor core, memory, peripherals, and I/O into one device. The MSP430 family belongs to the embedded-controller hierarchy: microcontroller, embedded processor, semiconductor, and integrated circuit. It is used where a compact control system must execute firmware, read inputs, operate timing functions, and control external circuitry within a defined board-level design.
The verified distributor information identifies MSP430U275IPM as an MSP430 Microcontroller IC and an ASIC for the Dolphin chipset. The same sources consistently identify the package as 64-LQFP (10x10), while DigChip specifies tray packaging. Detailed information such as flash memory, RAM, I/O count, clock speed, operating-temperature range, and detailed peripheral assignments was not present in the supplied excerpts and therefore remains unverified on this page.
Because the supplied source refers to the U275 as a Dolphin chipset ASIC rather than providing a conventional general-purpose MCU feature summary, engineers should evaluate the device from the complete manufacturer documentation for the specific embedded design. The 64-LQFP footprint also requires a PCB land pattern and pin assignment matching the exact ordering code; a 64-pin package alone does not prove function-level compatibility with another MSP430 device.
Typical design contexts for a 16-bit embedded controller include embedded system control, peripheral control, data acquisition, instrumentation, and compact industrial products. The 10 mm by 10 mm LQFP package provides a moderate-size surface-mount option for multilayer PCBs, while tray packaging is identified by the verified product listings. Exact suitability still depends on the unavailable memory, clock, I/O, and electrical specifications.
For new layouts, preserve the manufacturer-specified decoupling, programming interface, clock arrangement, and exposed or routed ground-network requirements from the complete datasheet. Also verify programming, debug, and supply-voltage compatibility before substituting this device into an existing design, especially when replacing a microcontroller with a superficially similar 64-LQFP part.
This page combines verified package, classification, packaging, inventory, and pricing information with explicit uncertainty notes, helping engineers separate confirmed data from fields that still require the full MSP430U275IPM datasheet for memory capacity, pinout, electrical limits, and lifecycle confirmation.

典型应用
MSP430U275IPM 适用于 6 应用s: Embedded System Control, Data Acquisition Controller, Industrial Instrumentation, Low-Power Device Control, Peripheral Sequencing and Control, Compact Embedded Products.
Embedded System Control
MSP430U275IPM is suitable for evaluation as an embedded controller when a design depends on the specific Texas Instruments 16-bit MSP430U275 Dolphin chipset ASIC. The confirmed 64-LQFP (10x10) surface-mount package provides a defined board footprint, while the 16-bit architecture identifies the controller class used for embedded sequencing and peripheral control. Engineers should verify the unavailable clock rate, memory sizes, I/O count, and interrupt structure in the complete manufacturer datasheet before finalizing firmware timing. The package must also be checked against the authoritative pin drawing because the supplied excerpts do not identify individual signals. This page therefore presents MSP430U275IPM as a design-specific controller candidate, not as a universally interchangeable MCU, and confirms its 64-LQFP construction and distributor availability as of 2026-10-28.
推荐
Data Acquisition Controller
The MSP430U275IPM can be considered for a data-acquisition controller role when firmware and hardware are specifically designed around its 16-bit MSP430U275 Dolphin chipset ASIC implementation. Its confirmed 64-LQFP (10x10) package is suitable for a multilayer PCB with controlled routing between the controller, sensing circuitry, and communications interface. The verified results do not provide ADC resolution, sampling rate, I/O count, timer resources, or memory capacity, so those values cannot be asserted in an acquisition design. A practical evaluation should compare sensor timing, conversion performance, data buffering, and interrupt latency against the full datasheet. Pin assignment, supply rails, programming access, and ground-return requirements should likewise be taken directly from the manufacturer documentation.
推荐
Industrial Instrumentation
For industrial instrumentation, MSP430U275IPM offers a confirmed 16-bit microcontroller-class device in a 64-LQFP surface-mount package. This makes it a candidate when an instrument controller, measurement sequencer, or front-end controller was designed around the U275 ASIC rather than a generic interchangeable MCU. The verified distributor records show a 10 mm by 10 mm LQFP body and tray packaging, enabling PCB and assembly planning. However, the excerpts do not establish the operating-temperature range, supply limits, oscillator accuracy, EMC characteristics, or watchdog resources. Those constraints are decisive for industrial deployment and remain unverified. The complete Texas Instruments documentation should therefore be reviewed for environmental ratings, clock behavior, reset logic, and peripheral coverage before the component is approved for production instrumentation.
推荐
Low-Power Device Control
MSP430U275IPM may fit a low-power embedded-control application if the design specifically depends on its 16-bit MSP430U275 ASIC behavior. The confirmed facts are the 64-LQFP (10x10) package, tray packaging, and MSP430 microcontroller classification. No verified active-current, standby-current, sleep-mode, or wake-up-time values were supplied, so this page cannot claim a battery-life advantage. Engineers should use the complete datasheet to compare sleep modes, clock start-up time, digital I/O leakage, analog leakage, and the behavior of on-board peripherals. If power consumption governs the design, measured current in the actual operating states is also necessary because board leakage and external pull networks can dominate a low-power budget. Package pin verification remains mandatory before schematic capture.
推荐
Peripheral Sequencing and Control
The 16-bit MSP430U275IPM controller is a candidate for deterministic peripheral sequencing, discrete control, and multi-function embedded logic when the board was designed around its Dolphin chipset ASIC implementation. A 64-LQFP (10x10) package provides enough physical scale for a conventional surface-mount assembly and supports integration with external drivers, logic, and communication components. The supplied evidence does not reveal timer resolution, interrupt latency, GPIO count, UART availability, or PWM resources, preventing those capabilities from being claimed directly. Design review should map every required output, timing condition, fault input, and shutdown path to the official pin table. Firmware developers should also confirm code-generation-device support, bootloader behavior, and programming voltage using complete manufacturer and toolchain documentation.
推荐
Compact Embedded Products
MSP430U275IPM can be evaluated for compact embedded products that require a Texas Instruments 16-bit controller-class component in a 64-LQFP package. Its 10 mm by 10 mm body is confirmed by multiple distributor listings, and the device was listed in tray packaging, which is useful for prototype and low-to-medium-volume assembly planning. This application should not be approved from package information alone: flash, RAM, I/O, voltage, clock, and environmental specifications were not exposed in the verified excerpts. For a new design, select MSP430U275IPM when existing software or a documented system architecture already uses the U275 ASIC. For broader product qualification, compare its complete specifications with other MSP430 controllers and confirm programming, supply sequencing, thermal performance, and lifecycle status through authorized Texas Instruments channels.

设计说明
Use the manufacturer package drawing for the 64-LQFP (10x10) land pattern and pin-1 orientation before routing the PCB. The verified distributor excerpts establish the body size but do not provide a pin table, pad dimensions, or recommended PCB geometry. Confirm those details in the full Texas Instruments documentation and verify the assembled board against the selected package rather than scaling the pad arrangement from a generic 64-pin library.
Validate the complete supply-voltage range, absolute maximum ratings, startup behavior, and power-supply sequencing requirements against the official MSP430U275IPM datasheet. Those electrical values were not included in the supplied sources, so no regulator or capacitor recommendation can be made safely. During bring-up, measure the supply at the device pins and confirm that every required power state satisfies the manufacturer's limits before enabling peripheral operation.
Do not treat a shared 64-LQFP package as proof that MSP430F149IPAGR, MSP430F235TPMR, or MSP430F5325IPNR is pin-to-pin compatible with MSP430U275IPM. Compare every power, ground, reset, clock, programming, and I/O signal, then verify software startup, interrupt mapping, and peripheral instance placement. The supplied evidence supports package comparison only, so board changes and firmware changes should both be expected unless the manufacturer explicitly approves a substitution.
合规信息
The supplied excerpts do not explicitly state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status for MSP430U275IPM. No compliance claim has been inferred from distributor availability.
