MSP430A155IPZ Présentation
A microcontroller is a semiconductor that integrates a processor core, nonvolatile program memory, data memory, I/O ports, and peripherals on one device. In the product hierarchy, the MSP430A155IPZ is a 16-bit RISC-based MCU within the MSP430 family and the broader embedded-controller category. It executes firmware from flash while using integrated communication, timing, watchdog, brown-out, DMA, LCD, and PWM resources.
Key verified features include 64 KB of flash organized as 64K x 8, a 16-bit core, operation up to 25 MHz, and 72 I/O pins. The connected peripherals include I2C, IrDA, LIN bus, SCI, SPI, and UART/USART. Additional listed resources include brown-out detection and reset, DMA, an LCD interface, power-on reset, PWM, and a watchdog timer. These peripherals reduce the need for discrete interface components in connected embedded systems.
The MSP430 architecture provides an RISC processor core identified as CPUXV2 in the supplied technical summary. Its 25 MHz operating speed gives it substantially more processing headroom than lower-frequency 8-bit control devices, while the 16-bit instruction and data path is well suited to compact control firmware. Because detailed clock, RAM, voltage, timing, and electrical limits were not included in the verified source text, they should be confirmed against the manufacturer datasheet before design release.
Typical uses include industrial sensor controllers, LIN-connected nodes, serial bridges, low-power data loggers, compact motor or actuator controllers, and communications modules. The broad interface set permits connection to sensors, displays, transceivers, and external storage while the LCD and PWM resources support local human-interface and output-control functions.
The primary design consideration is pin planning across the 100-LQFP footprint. Designers should preserve the MSP430A155IPZ power, ground, decoupling, programming, reset, crystal, and peripheral assignments shown in the official pinout. Because this is a 14 x 14 mm gull-wing package, PCB routing needs adequate escape space and assembly clearance.
This page consolidates the verified distributor specifications, sourcing information, application context, and compatibility limits for MSP430A155IPZ. It also distinguishes confirmed specifications from data that still requires datasheet-level engineering verification.

Applications typiques
MSP430A155IPZ convient pour 8 applications: LIN-Connected Industrial Sensor Controller, Low-Power Data Logger, Serial Protocol Bridge, LCD Instrument Panel, Compact Motor and Actuator Control, Portable Measurement Device, Communication Gateway, Secure Embedded Controller Platform.
LIN-Connected Industrial Sensor Controller
MSP430A155IPZ fits a LIN-connected sensor node because the verified device combines a 25 MHz CPUXV2 core, 72 I/O pins, 64 KB flash, and LIN bus support in a 100-LQFP package. Firmware can sample local sensing inputs, apply control logic, and service communication while the watchdog and brown-out reset support recovery. Using SCI, SPI, UART/USART, and I2C alongside LIN can connect sensors and external converters through fewer discrete interface devices. Final suitability still depends on confirming supply voltage, RAM, timer assignments, analog channels, and pin multiplexing in the manufacturer datasheet.
Recommandé
Low-Power Data Logger
A low-power data logger can use the MSP430A155IPZ as the supervisory controller because its verified 64 KB flash stores firmware while the 25 MHz CPUXV2 core handles acquisition sequencing, storage updates, and communications. I2C and SPI support efficient attachment of sensors, serial memories, or converters, while UART/USART and SCI provide host or service links. DMA can reduce interrupt servicing overhead for supported transfers, and the watchdog can restart a stalled acquisition task. The design must verify RAM depth, low-power modes, supply voltage, wake-up timing, and data-retention requirements before implementation.
Recommandé
Serial Protocol Bridge
MSP430A155IPZ is suitable for a multi-protocol bridge because the verified peripheral list includes I2C, IrDA, LIN bus, SCI, SPI, and UART/USART. The 25 MHz CPUXV2 core can translate frames, manage buffering, and coordinate handshakes, while DMA supports efficient movement of supported data streams. Its 72 I/O pins offer ample parallel I/O for status indicators, configuration straps, and peripheral control. Before routing the PCB, confirm which communication peripherals coexist on the selected device, their alternate pin functions, clock requirements, and exact 100-LQFP assignments.
Recommandé
LCD Instrument Panel
The MSP430A155IPZ can serve as the controller for an LCD instrument panel because LCD interface capability is explicitly listed alongside 72 I/O pins, PWM, and a 25 MHz 16-bit core. Firmware can acquire measurements, update a local display, operate controls, and expose service communications through I2C, SPI, SCI, or UART/USART. PWM resources can support indicator dimming or auxiliary control functions, while brown-out reset improves predictable recovery. Engineering must still verify the specific LCD segment or matrix interface, regulated supply requirements, panel drive timing, and available pins on the 100-LQFP footprint.
Recommandé
Compact Motor and Actuator Control
MSP430A155IPZ is applicable to compact actuator control because its verified feature set includes PWM, DMA, watchdog, brown-out reset, and extensive serial connectivity. The 25 MHz CPUXV2 core can execute position or duty-cycle logic, while PWM channels generate timed drive signals and communication blocks support supervisory commands. A 72-I/O device also provides room for encoders, switch inputs, fault signals, and external drivers. The exact PWM count, timer architecture, motor-driver interface, supply limits, and pin multiplexing are not supplied and must be confirmed before component selection.
Recommandé
Portable Measurement Device
MSP430A155IPZ can anchor a portable or battery-powered measurement device when its low-power operating modes and analog resources support the required measurement chain, but those details are not established in the supplied source text. The verified 25 MHz CPUXV2 core and 64 KB flash provide processing and firmware capacity, while I2C, SPI, UART/USART, and SCI simplify connection to sensors, displays, and service interfaces. Brown-out reset and the watchdog are useful for controlled recovery. Designers must verify average-current targets, sleep-mode timing, RAM, ADC resources, reference accuracy, and battery voltage limits using the current manufacturer documentation.
Recommandé
Communication Gateway
MSP430A155IPZ is a viable gateway controller for designs that need several embedded serial functions in one industrial-grade device. Verified connectivity includes LIN, I2C, IrDA, SCI, SPI, and UART/USART, while the 25 MHz CPUXV2 core and 72 I/O pins support protocol translation, diagnostics, and status routing. Adding a network companion can extend the gateway beyond point-to-point links, although the MCU must be validated for throughput and simultaneous peripheral requirements. Firmware scheduling, buffer memory, watchdog behavior, bus timing, and package-level signal integrity should be prototyped before production.
Recommandé
Secure Embedded Controller Platform
MSP430A155IPZ can serve as the base controller in a secure embedded platform when its watchdog, brown-out reset, controlled 25 MHz core, and 64 KB flash fit the system threat model. These resources support startup checks, task supervision, fault detection, and deterministic control routines, while multiple serial interfaces connect local sensors and service equipment. The 100-LQFP package exposes a large pin count for status, isolation, and expansion options. Security capability is not established by the verified data, so firmware signing, key storage, debug-lock features, physical protection, and update architecture require separate review.

Notes de conception
Treat the 100-LQFP footprint as a fine-pitch routing problem. The verified package is square, gull-wing, 14 x 14 mm, and has 100 terminals, but individual signal assignments were not supplied. Before schematic release, compare every power, ground, reset, programming, clock, and alternate-function connection against the current manufacturer pin table. Preserve pin-1 orientation and land-pattern tolerances from the official package drawing, and reserve clean escape paths between adjacent fine-pitch pads.
Do not select the power supply or decoupling values from the distributor summary because the MSP430A155IPZ supply-voltage range and current limits are [DATA_NEEDED: operating supply voltage range and current limits]. Confirm digital and analog supply requirements, internal regulator behavior, external clock needs, and power-up sequencing in the manufacturer datasheet. Then place the prescribed bypass capacitors close to their associated supply pins and provide a return path that does not force high-frequency current through sensitive signal ground.
Do not substitute an MCU merely because it is also an MSP430 or runs at 25 MHz. A drop-in decision requires an exact 100-LQFP footprint match, compatible pin multiplexing, supply levels, programming signals, reset behavior, clock implementation, peripheral mapping, and timing constraints. The supplied cross-reference results named no verified substitute. Compare the full manufacturer datasheets and, where migration affects firmware, review device differences and qualification before releasing a replacement.
Plan communication and clock signals from the verified peripheral set rather than assigning pins by assumption. I2C, IrDA, LIN, SCI, SPI, UART/USART, and PWM may depend on alternate pin functions and peripheral instances that are not identified in the supplied evidence. Verify the active-pin matrix, route high-speed or sensitive nets away from switching nodes, maintain uninterrupted ground references, and apply the manufacturer’s rise-time and capacitance guidance once the exact operating mode is known.
Use the verified watchdog and brown-out reset resources as part of the control-system failure strategy, but validate the reset topology and timeout behavior against the current datasheet. In firmware, define safe outputs before enabling actuators, release reset in the prescribed sequence, and exercise watchdog recovery under brown-out and communication-failure tests. Avoid routine watchdog resets as substitutes for fixing blocked interrupts, incorrect clock setup, or driver defects.
Informations de conformité
The verified sources identify an industrial temperature grade but do not provide RoHS, REACH, lead-free, halogen-free, or conflict-minerals declarations. AEC-Q100 is not_applicable because MSP430A155IPZ is described as industrial grade rather than an automotive-qualified variant.
