Product details
Overview
MSP430F1471IPMRG from Texas Instruments is an ultra-low-power 16-bit RISC microcontroller with 32KB flash, 1KB RAM, dual USARTs, 12-bit ADC (8-channel), two 16-bit timers (Timer_A3 and Timer_B7), and integrated comparator-designed for battery-powered sensor systems and portable instrumentation requiring sub-µA standby current and <6 µs wake-up.
For engineers reviewing the MSP430F1471IPMRG datasheet, MSP430F1471IPMRG pinout, MSP430F1471IPMRG application, or MSP430F1471IPMRG equivalent, this page delivers verified specifications, package-confirmed pin functions, real-world use cases, and validated alternative options for industrial metering, low-power sensing, and embedded control design.
Technical Context
The MSP430F1471IPMRG implements a 16-bit CPU with constant generators and hardware multiplier, enabling high code efficiency in ultra-low-power operation. Its five power-saving modes-including LPM3 with 1.6 µA standby and 0.1 µA RAM-retention off mode-are optimized for extended battery life in intermittent-sampling applications.
It integrates dual asynchronous/synchronous serial interfaces (USART0/USART1), a 12-bit ADC with internal reference and autoscan, and Timer_B7 with seven capture/compare registers and shadow registers-supporting precise PWM generation, input capture, and time-critical event handling without CPU intervention.

FAQ
What is the package type and pin count of the MSP430F1471IPMRG?
The MSP430F1471IPMRG uses a 64-pin LQFP (PM) package with 10 mm × 10 mm body size and an exposed thermal pad. It is functionally and pin-compatible with the PAG and RTD variants in the same family, but the 'PM' suffix specifically denotes the leaded quad flat pack variant used in the MSP430F1471IPMRG ordering code.
Does the MSP430F1471IPMRG support both UART and SPI on its USART modules?
Yes, the MSP430F1471IPMRG features two fully configurable USART modules (USART0 and USART1), each capable of operating in asynchronous UART mode or synchronous SPI mode. This dual-mode flexibility allows the MSP430F1471IPMRG to serve as a UART-to-SPI bridge or manage separate communication channels for host interface and peripheral control simultaneously.
What is the maximum ADC resolution and channel count supported by the MSP430F1471IPMRG?
The MSP430F1471IPMRG integrates a 12-bit successive-approximation ADC (ADC12) with eight analog input channels (A0–A7). It supports internal reference (1.5 V or 2.5 V), external reference, and sample-and-hold functionality-with conversion times under 10 µs-enabling high-fidelity sensor acquisition in low-power embedded systems.
How does the MSP430F1471IPMRG achieve ultra-low-power operation?
The MSP430F1471IPMRG achieves ultra-low-power operation through five configurable low-power modes (LPM0–LPM4), a digitally controlled oscillator (DCO) that wakes the CPU in under 6 µs from LPM3, and sub-µA current draw: 1.6 µA in standby and 0.1 µA in RAM-retention off mode. These features are validated in TI's SLAS272H datasheet under recommended operating conditions.
Is the MSP430F1471IPMRG pin-compatible with other devices in the MSP430F14x1 family?
Yes, the MSP430F1471IPMRG is pin-compatible with MSP430F1481IPMRG and MSP430F1491IRTD across shared 64-pin packages (PM and RTD). All MSP430F14x1 devices share identical pin functions, electrical characteristics, and memory-mapped peripherals-allowing scalable firmware reuse and hardware design migration within the family.
