Product details
Overview
MSP430A025IPM 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 MSP430A025IPM datasheet, MSP430A025IPM pinout, MSP430A025IPM application, or MSP430A025IPM equivalent, this page delivers verified technical context, exact pin functions for LQFP-64 package, real-world use cases in metering and industrial sensing, and validated alternative parts with documented functional and packaging differences.
Technical Context
The MSP430A025IPM 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 wake-up from LPM3 in under 6 µs. Its memory-mapped peripheral architecture integrates ADC12 with internal reference and autoscan, dual USARTs supporting UART/SPI, and JTAG-based debugging.
It supports five low-power modes (LPM0–LPM4), with RAM retention in Off mode at 0.1 µA. The device uses separate analog (AVCC/AVSS) and digital (DVCC/DVSS) supplies, includes Schmitt-trigger inputs on all I/O ports, and features programmable code protection via security fuse - all optimized for long-life embedded measurement applications.

FAQ
What is the maximum operating frequency of the MSP430A025IPM?
The MSP430A025IPM operates at up to 8 MHz using its digitally controlled oscillator (DCO), with typical active-mode performance specified at 1 MHz (280 µA). Its 125-ns instruction cycle enables deterministic real-time response for time-critical sensor tasks - a key capability confirmed in the SLAS272H datasheet revision May 2018.
Does the MSP430A025IPM support hardware UART and SPI simultaneously?
Yes, the MSP430A025IPM integrates two independent USART modules (USART0 and USART1), each configurable as either UART or SPI. This allows concurrent full-duplex UART communication with a host and synchronous SPI interface to an external ADC or sensor - verified in Section 1.1 and Table 3-1 of the official datasheet.
What is the ADC resolution and channel count on the MSP430A025IPM?
The MSP430A025IPM features a 12-bit ADC12 module with eight input channels (A0–A7), supporting internal reference, external reference, and sample-and-hold operation. Conversion time is <10 µs, and autoscan mode enables automatic sequential sampling - all confirmed in the Device Overview and Section 5.23–5.27 of SLAS272H.
Is the MSP430A025IPM pin-compatible with other MSP430F14x devices?
Yes, the MSP430A025IPM shares the same LQFP-64 pinout and electrical characteristics as MSP430F149IPM and MSP430F148IPM, including identical signal assignments for P1–P6, JTAG, power, and oscillator pins - as shown in Figure 4-2 and Table 4-1 of the datasheet.
What low-power modes does the MSP430A025IPM support, and what are their typical currents?
The MSP430A025IPM supports five low-power modes: LPM0–LPM4. Standby (LPM3) draws 1.6 µA; Off mode (LPM4) with RAM retention consumes 0.1 µA. Wake-up from LPM3 occurs in <6 µs - values measured per recommended operating conditions in Section 5.3 and Section 5.13 of SLAS272H.
