MSP430A002IPM - 16-Bit 8MHz MCU 32KB Flash | Texas Instruments
料号： MSP430A002IPM ✓ 量产中MSP430A002IPM 概述
A microcontroller is a programmable integrated circuit that combines a processor core, memory, and peripherals into one device. The MSP430 belongs to the embedded microcontroller hierarchy and is designed to execute firmware, acquire measurements, control outputs, and manage communications in compact electronic systems. This particular MSP430x1xx device is positioned for low-power embedded control rather than high-performance computing.
Key verified features include 32 KB of Flash memory, 1 KB of RAM, 48 I/O ports, a 12-bit ADC, and two USART interfaces. The 8 MHz clock provides a defined processing-rate reference for control loops and peripheral service, while the 1.8 V to 3.6 V supply range supports common low-voltage embedded rails. The industrial temperature grade and 64-terminal surface-mount package suit equipment where a conventional LQFP footprint is required.
The MSP430 architecture is based on a 16-bit RISC core and integrates flash-backed firmware storage with on-chip RAM. Its mixed-signal and communications resources allow one device to handle sensor conditioning, control logic, and serial communications. Two USARTs can support asynchronous UART or synchronous SPI functions, although the exact peripheral routing and operating limits must be confirmed against the manufacturer datasheet and the selected board design.
Typical uses include industrial instrumentation, data acquisition, embedded control, sensor-interface equipment, and communication-enabled low-power systems. The 48 I/O ports provide substantial external connectivity for discrete inputs and outputs, while the 12-bit ADC supports analog measurement channels. The two USARTs can reduce the need for separate interface controllers when the system architecture permits their shared use.
When designing around MSP430A002IPM, verify the exact pin multiplexing, power requirements, clock configuration, ADC channels, and programming interface against the official 64-pin pinout. Use a PCB layout and decoupling arrangement that follows the manufacturer guidance. Because the verified data identifies the package as 64-LQFP (10x10), the library package key is lqfp-64 and the pinout must contain 64 entries.
This page consolidates the verified distributor and manufacturer-related specifications, while clearly flagging details that were not supplied. It also distinguishes confirmed attributes from unavailable pin-level, pricing, compliance, and substitute information so engineers can make a traceable procurement and design decision.

典型应用
MSP430A002IPM 适用于 6 应用s: Industrial Sensor Acquisition, Data Logger, UART Communication Controller, Low-Voltage Embedded Control, Instrumentation Interface, Compact Control Board.
Industrial Sensor Acquisition
MSP430A002IPM fits industrial sensor-acquisition designs that require an embedded controller, analog measurement, and communication in one device. The verified 12-bit ADC provides a defined conversion-resolution target, while 1 KB of RAM can support short acquisition buffers and control state. Its 48 I/O ports are useful for sensor-enable lines, thresholds, status indicators, and interface signals. The 1.8 V to 3.6 V supply range also fits low-voltage industrial embedded rails. Before layout, verify ADC channel availability, input limits, sampling timing, and pin multiplexing in the manufacturer datasheet; the verified record does not specify those details.
推荐
Data Logger
The MSP430A002IPM can serve as the control core in a compact embedded data logger when the design needs local sensor reading, serial transfer, and nonvolatile firmware storage. Its 32 KB Flash plus 256 bytes provides the verified program-memory basis for firmware, and 1 KB RAM can hold a limited working buffer. The two USARTs may assist with external sensors or host communication, subject to exact peripheral routing. Because no external memory interface, storage capacity, or ADC channel list was provided, the data-logging architecture must be sized conservatively and validated against the official datasheet.
推荐
UART Communication Controller
MSP430A002IPM is appropriate for an embedded UART or synchronous-SPI communication node because the verified data identifies two USART interfaces supporting asynchronous UART or synchronous SPI functions. The 16-bit core and 8 MHz clock provide the processing basis for protocol handling, while 48 I/O ports can support ancillary control signals. The actual baud rate, pin multiplexing, and simultaneous peripheral availability are not supplied, so they must be confirmed before board design. Use the USART pins shown in the official pinout and account for signal conditioning if the connected device uses non-TTL logic levels.
推荐
Low-Voltage Embedded Control
MSP430A002IPM fits low-voltage embedded-control equipment operating from a 1.8 V to 3.6 V supply. The 16-bit RISC core handles control tasks, the 32 KB Flash stores application firmware, and the 48 I/O ports provide connectivity to relays, indicators, sensors, and actuators. The device is especially useful when a mixed-signal controller and serial interfaces are needed without adding several separate support ICs. The industrial temperature grade is reported in the verified data, but exact current consumption, clock options, reset behavior, and operating-temperature limits were not supplied. Confirm those details before defining the power budget and regulator selection.
推荐
Instrumentation Interface
MSP430A002IPM can support instrumentation interfaces that combine local control, measurement, and host communication. The 12-bit ADC is a useful starting point for analog front-end signals, while the two USARTs can provide connectivity to measurement peripherals or a system controller. The 48 I/O ports give the designer additional lines for range selection, calibration controls, status reporting, and digital interfaces. Exact analog input count, reference voltage, sampling mode, and serial timing are not present in the verified data, so the instrumentation specification must be finalized from the manufacturer datasheet and validated with prototype measurements.
推荐
Compact Control Board
The 64-LQFP package and 48 I/O ports make MSP430A002IPM relevant to compact control boards requiring a moderate pin count and surface-mount assembly. The 8 MHz core provides a clear timing reference for simple control loops, while 32 KB Flash and 1 KB RAM are sufficient for many lightweight embedded applications. The package is identified as 10 mm × 10 mm, so it is larger than many fine-pitch mixed-signal MCUs but still suitable for conventional multilayer PCBs. Confirm land pattern, exposed-pad requirements, power pins, programming pins, and analog routing against the official mechanical and electrical documentation.

设计说明
Use the verified 64-LQFP 10 mm × 10 mm package designation as the starting point for PCB footprint selection, but obtain the official Texas Instruments package drawing before placing pads. Confirm pad numbering, lead pitch, pin-1 orientation, and any exposed-pad requirements. The supplied data does not include a pin-level diagram, so a generic 64-pin footprint should not be assumed to be electrically interchangeable.
Design the supply rail for the verified 1.8 V to 3.6 V operating range and verify regulator tolerance, startup sequencing, and decoupling against the manufacturer datasheet. The supplied results do not state current consumption or analog-reference requirements. Before finalizing the power tree, check every peripheral configuration, especially when the ADC and two USARTs are active, rather than estimating current from the 8 MHz clock alone.
Do not treat all 64 package terminals as interchangeable GPIO. The verified 48 I/O count is a device-level figure, while power, clock, reset, programming, and multiplexed peripheral pins may have different functions. Map the complete official pinout, verify alternate-function conflicts, and confirm that the two USART interfaces and ADC channels are available on the pins selected by the PCB design.
Keep analog sensor inputs and the ADC routing away from noisy switching or high-current paths, and follow the manufacturer's guidance for grounding and decoupling. The verified data confirms a 12-bit ADC but does not provide its input range, reference source, acquisition time, or recommended layout. Those missing details must come from the official datasheet before defining the analog front end, sampling network, or PCB keepouts.
合规信息
The supplied verified results do not explicitly state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status for MSP430A002IPM. Industrial temperature grade is reported, but that grade alone does not establish automotive qualification.
