Product details
Overview
MSP430A026IPM 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 48 general-purpose I/O pins in a 64-pin LQFP package. It targets battery-powered sensor systems and industrial control applications requiring sub-6 µs wake-up from standby mode and operation across 1.8–3.6 V.
For engineers reviewing the MSP430A026IPM datasheet, MSP430A026IPM pinout, MSP430A026IPM application, or MSP430A026IPM equivalent, key selection criteria include its 60KB flash memory size, dual USART support (UART/SPI), 12-bit ADC conversion time under 10 µs, integrated hardware multiplier, and compatibility with TI's MSP430x1xx development ecosystem.
Technical Context
The MSP430A026IPM implements a 16-bit RISC CPU with constant generators and a digitally controlled oscillator (DCO), enabling active-mode current of 280 µA at 1 MHz/2.2 V and standby-mode current of 1.6 µA. Its five low-power modes-including LPM3 with wake-up in <6 µs-are optimized for extended battery life in portable measurement devices.
It integrates a 12-bit ADC12 module with internal reference, sample-and-hold, autoscan, and temperature sensor support; two independent 16-bit timers (Timer_A3 with three capture/compare registers, Timer_B7 with seven plus shadow registers); and an on-chip comparator. The device supports JTAG-based debugging and serial bootloader programming without external voltage.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430F149IPM | Identical core, peripherals, and pinout; differs only in marking and qualification - MSP430A026IPM is the commercial-grade variant of MSP430F149IPM | No functional difference; both support same firmware, tools, and development boards | Select MSP430A026IPM for cost-sensitive commercial designs; MSP430F149IPM preferred for automotive-qualified supply chains |
| MSP430F1612IPM | Same 64-pin LQFP package and 16-bit architecture but with 55KB flash, 5KB RAM, and enhanced DMA controller - no hardware multiplier | Better suited for data-intensive applications requiring larger RAM buffers but less arithmetic intensity | Choose MSP430F1612IPM when firmware requires >2KB RAM or DMA-accelerated peripheral transfers; avoid if hardware multiply is essential |
Compared with MSP430F149IPM, the MSP430A026IPM offers identical functionality at commercial-grade reliability and pricing, while MSP430F1612IPM trades hardware multiply for expanded RAM and DMA-making it preferable for streaming sensor data but less optimal for real-time signal math.

FAQ
What is the maximum operating frequency of the MSP430A026IPM?
The MSP430A026IPM does not have a fixed maximum clock frequency specification; instead, it uses a digitally controlled oscillator (DCO) calibrated to deliver stable operation up to 8 MHz across voltage and temperature ranges. Its 125-ns instruction cycle corresponds to a 8-MHz CPU clock, and all peripherals-including ADC12 and USARTs-are fully functional at this rate. The DCO can be fine-tuned using the FLL+ module for precise timing control in the MSP430A026IPM.
Does the MSP430A026IPM support in-system programming without external hardware?
Yes, the MSP430A026IPM supports in-system programming via its built-in bootloader (BSL), accessible through UART using only the RST/NMI, TCK, and TDO/TDI pins. No external programming voltage is required, and the BSL remains active even after flash security fuse programming. This enables field firmware updates directly over the MSP430A026IPM's USART0 interface without dedicated JTAG hardware.
How many analog input channels does the MSP430A026IPM ADC support?
The MSP430A026IPM integrates the ADC12 module with eight selectable analog input channels (A0–A7), mapped to P6.0 through P6.7. These inputs support single-ended or differential measurements, internal temperature sensor reading, and external reference voltage configuration. All eight channels are accessible simultaneously in autoscan mode, allowing continuous multiplexed sampling without CPU intervention in the MSP430A026IPM.
Is the MSP430A026IPM pin-compatible with other MSP430F14x devices?
Yes, the MSP430A026IPM is fully pin-compatible with all 64-pin LQFP variants in the MSP430F14x family-including MSP430F149IPM, MSP430F148IPM, and MSP430F147IPM-sharing identical pin functions, electrical characteristics, and package dimensions (10 mm × 10 mm). This allows direct substitution in existing PCB layouts designed for those parts, provided firmware accounts for flash/RAM size differences in the MSP430A026IPM.
What development tools are officially supported for the MSP430A026IPM?
Texas Instruments officially supports the MSP430A026IPM with Code Composer Studio (CCS) IDE, MSP430Ware peripheral driver library, and the MSP-TS430PM64 target socket board. Debugging is enabled via standard JTAG or Spy-Bi-Wire interfaces using the MSP-FET programmer. TI's MSP430G2 LaunchPad is not compatible; only FET-based debuggers supporting the full 64-pin pinout are certified for use with the MSP430A026IPM.
