Product details
Overview
MSP430A064IPM 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 metering applications operating from 1.8 V to 3.6 V.
For engineers reviewing the MSP430A064IPM datasheet, MSP430A064IPM pinout, MSP430A064IPM application, or MSP430A064IPM equivalent, key selection considerations include its LQFP-64 package, 48 I/O pins with interrupt capability, wake-up time under 6 µs from standby, and dual USART support for UART/SPI communication in industrial sensing and handheld instrumentation designs.
Technical Context
The MSP430A064IPM implements a 16-bit RISC CPU with constant generators and a digitally controlled oscillator (DCO), enabling sub-6-µs wake-up from LPM3 standby mode. Its memory-mapped peripherals include ADC12 with internal reference and autoscan, Timer_B7 with seven capture/compare registers and shadow registers, and Timer_A3 with three capture/compare registers.
It supports two independent USART modules (USART0 and USART1), each configurable as asynchronous UART or synchronous SPI, and integrates a comparator, watchdog timer, and JTAG-based emulation module - all optimized for low-power operation across five power-saving modes including RAM-retention off mode (0.1 µA).

FAQ
What is the maximum ADC sampling rate supported by the MSP430A064IPM?
The MSP430A064IPM ADC12 achieves <10 µs conversion time per sample, enabling up to 100 kSPS in single-channel mode. With autoscan enabled across all 8 channels, effective throughput is ~12.5 kSPS per channel. The ADC clock (ADC12CLK) is derived from SMCLK or DCO and configurable via divider settings to meet specific resolution/speed trade-offs in the MSP430A064IPM design.
Does the MSP430A064IPM support both UART and SPI on its USART modules?
Yes, the MSP430A064IPM includes two fully independent USART modules (USART0 and USART1), each configurable in either asynchronous UART mode or synchronous SPI mode. This allows simultaneous use - for example, USART0 as UART for debug logging and USART1 as SPI master for sensor communication - without shared resources or timing conflicts in the MSP430A064IPM implementation.
What is the wake-up time from LPM3 standby mode for the MSP430A064IPM?
The MSP430A064IPM wakes up from LPM3 (standby with VLO running) in less than 6 µs, as verified in the official SLAS272H datasheet. This fast transition enables responsive event-driven operation while maintaining ultra-low average current - a key specification confirmed for the MSP430A064IPM across its full operating voltage and temperature range.
Is the MSP430A064IPM pin-compatible with other devices in the MSP430F14x family?
Yes, the MSP430A064IPM is pin-compatible with MSP430F149IPM and MSP430F1491IRTD in their respective LQFP-64 and VQFN-64 packages. Signal mapping, power pin locations, and JTAG interface match exactly for the LQFP variant, allowing drop-in replacement in existing MSP430F149IPM designs without PCB revision - a verified compatibility for the MSP430A064IPM.
What development tools are officially supported for the MSP430A064IPM?
Texas Instruments officially supports the MSP430A064IPM with MSP-FET430UIF debugger, MSP-TS430PM64 target socket board, and Code Composer Studio v12+ IDE. The device is also compatible with MSP430 LaunchPad development kits (e.g., MSP-EXP430F5529LP) via firmware adaptation, and all TI-provided MSP430Ware drivers and example projects apply directly to the MSP430A064IPM.
