Product details
Overview
MSP430A002IPM from Texas Instruments is a 16-bit ultra-low-power mixed-signal microcontroller featuring 60KB flash, 2KB RAM, dual USARTs, 12-bit ADC with 8 channels, two 16-bit timers (Timer_A3 and Timer_B7), and hardware multiplier - designed for battery-powered sensor systems and portable instrumentation requiring sub-µA standby current and <6 µs wake-up.
For engineers reviewing the MSP430A002IPM datasheet, MSP430A002IPM pinout, MSP430A002IPM application, or MSP430A002IPM equivalent, this page delivers verified specifications, LQFP-64 package details, functional pin mapping, real-world use cases in industrial sensing and metering, and validated alternative parts for design continuity.
Technical Context
The MSP430A002IPM implements a 16-bit RISC CPU with constant generators and a digitally controlled oscillator (DCO), enabling active-mode operation at 1 MHz with only 280 µA and standby current as low as 1.6 µA. Its memory-mapped peripherals include ADC12 with internal reference and autoscan, dual USARTs supporting UART/SPI, and JTAG-based debug interface.
It supports five power-saving modes, including LPM3 with RTC-capable ACLK and RAM retention at 0.1 µA. The device integrates 48 general-purpose I/O pins across six ports, with configurable Schmitt-trigger inputs, programmable drive strength, and interrupt capability on all port pins - optimized for deterministic low-power system control.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-low-power mixed-signal microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430F149IPM | Identical core, peripherals, and pinout; same 60KB flash/2KB RAM; differs only in marking and qualification grade (F149 = production grade, A002 = automotive-grade variant) | Qualified per AEC-Q100 Grade 2 (−40°C to +105°C); includes extended temperature screening and traceability | Select MSP430A002IPM for automotive, transportation, or industrial environments requiring guaranteed operation beyond 85°C. |
| MSP430F1491IPM | Same architecture and memory; lacks XT2 oscillator circuitry - no support for 4–16 MHz crystals or high-speed SMCLK | Suitable for cost-sensitive, lower-performance applications where 1 MHz DCO or 32.768 kHz ACLK suffices | Choose MSP430F1491IPM when high-speed ADC sampling or fast UART baud rates are not required - saves BOM cost and layout area. |
Compared with MSP430F149IPM, the MSP430A002IPM adds automotive qualification without sacrificing performance or pin compatibility; versus MSP430F1491IPM, it retains full XT2 capability for precision timing-critical applications like synchronized sensor arrays or high-baud-rate telemetry.

What is the operating temperature range of the MSP430A002IPM?
The MSP430A002IPM is qualified for −40°C to +105°C operation per AEC-Q100 Grade 2, making it suitable for under-hood automotive, industrial control cabinets, and outdoor metering enclosures where extended thermal margins are required - unlike commercial-grade MSP430F149IPM (−40°C to +85°C).
Does the MSP430A002IPM support both UART and SPI on its USART modules?
Yes, the MSP430A002IPM includes two fully independent USART modules (USART0 and USART1), each configurable in hardware as either asynchronous UART or synchronous SPI - enabling simultaneous RS-232 diagnostics and SPI-connected sensor interfaces without software bit-banging.
How does the ADC12 module in the MSP430A002IPM differ from earlier MSP430 generations?
The ADC12 in the MSP430A002IPM provides 12-bit resolution with 8 selectable input channels, built-in reference (1.5 V or 2.5 V), sample-and-hold, autoscan mode, and conversion times under 10 µs - a direct upgrade from the 10-bit ADC in MSP430F13x devices and significantly more integrated than external ADC solutions requiring separate reference and timing circuits.
Can the MSP430A002IPM be programmed in-system without a dedicated programmer?
Yes, the MSP430A002IPM supports UART-based bootloader (BSL) programming via USART0 or USART1 using only RX/TX lines and RST - no external programming voltage or JTAG adapter needed. Firmware updates can be performed in the field using standard terminal commands and TI's BSL script tools.
