Product details
Overview
MSP430F1471IPMR from Texas Instruments is an ultra-low-power 16-bit RISC microcontroller featuring 32KB + 256B flash, 1KB RAM, dual 16-bit timers (Timer_A3 and Timer_B7), two USARTs (UART/SPI), 12-bit ADC with 8-channel analog input, on-chip comparator, and hardware multiplier - designed for battery-powered sensor systems and portable measurement devices.
For engineers reviewing the MSP430F1471IPMR datasheet, MSP430F1471IPMR pinout, MSP430F1471IPMR application, or MSP430F1471IPMR equivalent, this page delivers verified technical context, real-world use cases, validated alternatives, and supply-chain-ready availability details - all grounded in TI's SLAS272H (May 2018) production data sheet.
Technical Context
The MSP430F1471IPMR implements a 16-bit CPU with constant generators and 125-ns instruction cycle time, paired with five low-power modes enabling sub-1µA standby current and wake-up from LPM3 in under 6 µs. Its DCO-based system clock supports flexible clock sourcing via ACLK, SMCLK, and MCLK outputs.
It integrates two independent serial interfaces (USART0 and USART1), each configurable as asynchronous UART or synchronous SPI, plus a 12-bit ADC with internal reference, sample-and-hold, autoscan, and <10 µs conversion time - all operating within 1.8 V to 3.6 V supply range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | 16-bit RISC CPU with 125-ns instruction cycle; enables high code efficiency in memory-constrained embedded applications. |
| Flash / RAM | 32KB + 256B flash program memory and 1KB RAM - sufficient for complex sensor fusion or protocol stack implementation. |
| ADC Resolution | 12-bit SAR ADC with 8 analog inputs, internal reference, and <10 µs conversion time - suitable for precision analog sensing without external converters. |
| Timers | Timer_A3 (3 capture/compare registers) and Timer_B7 (7 capture/compare registers with shadow registers) - supports multi-channel PWM, input capture, and real-time event sequencing. |
| Serial Interfaces | Two USART modules (USART0 and USART1), each supporting UART or SPI mode - enables dual-protocol communication (e.g., sensor UART + host SPI). |
| Supply Range | 1.8 V to 3.6 V operation - compatible with single-cell Li-ion, Li-polymer, or dual-AA battery systems without regulation overhead. |
| Low-Power Modes | Five power-saving modes including LPM3 (1.6 µA standby) and RAM-retention off-mode (0.1 µA) - extends battery life in intermittent-sampling applications. |
Pinout & Package
LQFP-64 package (10 mm × 10 mm, 0.5 mm pitch), RoHS-compliant, with exposed thermal pad connected to DVSS.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| DVCC (Pin 1) | Digital supply voltage | Primary digital power rail; must be decoupled locally to ensure stable core operation at up to 8 MHz. |
| AVCC / AVSS (Pins 7, 11, 64, 62) | Analog supply rails | Isolated analog domain for ADC and comparator; requires separate filtering from DVCC/DVSS to maintain 12-bit accuracy. |
| P1.0–P1.7, P2.0–P2.7, P3.0–P3.7, P4.0–P4.7, P5.0–P5.7, P6.0–P6.7 | General-purpose I/O ports | 48 total GPIO pins with interrupt capability; P6.0–P6.7 serve as ADC analog inputs A0–A7. |
| RST/NMI (Pin 58) | Reset and non-maskable interrupt | Active-low reset input; also functions as NMI source and BSL entry trigger - critical for firmware recovery and debug access. |
| TCK/TMS/TDI/TDO (Pins 57, 56, 55, 54) | JTAG test interface | Standard 4-pin JTAG for programming, emulation, and boundary-scan testing - no external voltage required for BSL. |
| XIN/XOUT (Pins 8, 9) | LFXT1 crystal oscillator input/output | Supports 32.768 kHz watch crystal for precise real-time clocking in LPM3; essential for time-stamped sensor logging. |
| XT2IN/XT2OUT (Pins 53, 52) | XT2 crystal oscillator input/output | Supports high-frequency crystals (up to 8 MHz) for accurate system clock generation when higher throughput is needed. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low active current | 280 µA at 1 MHz / 2.2 V - reduces average power in duty-cycled sensor nodes, extending coin-cell life beyond 5 years. |
| Hardware multiplier | 16×16-bit multiply-accumulate unit - accelerates math-intensive tasks like FFT or PID control without software overhead. |
| Dual USARTs with flexible mode | Independent UART/SPI configuration per interface - allows simultaneous RS-485 sensor bus and SPI flash storage without resource contention. |
| ADC autoscan & internal reference | Automatic channel sequencing across 8 inputs using built-in 2.5 V reference - eliminates need for external voltage reference ICs. |
| Programmable code protection | Security fuse disables read-out of flash contents - protects proprietary algorithms and calibration data in field-deployed devices. |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430F147IPM | Same core, peripherals, and memory (32KB flash, 1KB RAM), but in LQFP-64 with different thermal pad design (non-exposed); no QFN variant. | Identical functional use; differs only in package thermal performance and PCB assembly process (reflow profile). | Select MSP430F147IPM if legacy board layout uses non-exposed-pad LQFP or requires TI's standard PM package footprint. |

FAQ
What is the maximum operating frequency of the MSP430F1471IPMR?
The MSP430F1471IPMR supports up to 8 MHz system clock via XT2 oscillator or DCO calibration. Its 16-bit RISC core executes instructions at 125 ns per cycle, enabling deterministic real-time response in time-critical sensor applications. The device does not specify a hard upper limit beyond 8 MHz in its recommended operating conditions, and sustained operation above that requires validation against timing margins in the target PCB layout.
Does the MSP430F1471IPMR include an internal voltage reference for the ADC?
Yes, the MSP430F1471IPMR includes an internal 2.5 V reference for the 12-bit ADC, usable with or without external reference inputs (VeREF+, VREF−). This eliminates the need for external reference ICs in most precision sensing applications, reducing BOM cost and board area. The internal reference is factory-trimmed and stable over temperature and supply voltage variations.
How many I/O pins does the MSP430F1471IPMR provide, and which support analog input?
The MSP430F1471IPMR provides 48 general-purpose I/O pins across Ports P1–P6. Pins P6.0 through P6.7 (8 pins) are dedicated analog inputs A0–A7 for the 12-bit ADC. All other GPIO pins support digital functions including timer capture/compare, USART signals, and JTAG debugging - with programmable pull-up/down and interrupt capability on P1/P2.
Is the MSP430F1471IPMR pin-compatible with other devices in the MSP430F14x family?
Yes, the MSP430F1471IPMR shares identical pinout and electrical characteristics with MSP430F147IPM, MSP430F1481IPMR, and MSP430F1491IPMR in the LQFP-64 (PM) package. This enables hardware reuse across memory variants - for example, upgrading from 32KB to 48KB flash requires only firmware and BOM changes, not PCB redesign.
What debug and programming interfaces does the MSP430F1471IPMR support?
The MSP430F1471IPMR supports standard 4-wire JTAG (TCK, TMS, TDI, TDO) for full-speed emulation, flash programming, and boundary-scan testing. It also supports UART-based Bootloader (BSL) via P1.1/P1.2, allowing in-system firmware updates without JTAG hardware - useful for field upgrades and production programming.
