Product details
Overview
MSP430F5171IYFFR from Texas Instruments is an ultra-low-power 16-bit RISC microcontroller in a 40-pin DSBGA (YFF) package, featuring 32 KB flash, 2 KB RAM, dual 16-bit Timer_D modules (TD0/TD1), USCI_A0 (UART/IrDA/SPI) and USCI_B0 (I²C/SPI), 16-channel comparator, and 5-V-tolerant I/Os. It operates from 1.8 V to 3.6 V and targets battery-powered sensor systems and digital power control.
For engineers reviewing the MSP430F5171IYFFR datasheet, MSP430F5171IYFFR pinout, MSP430F5171IYFFR application, or MSP430F5171IYFFR equivalent, key selection criteria include its LPM4.5 shutdown current (0.25 µA at 3 V), 40-pin DSBGA footprint, absence of integrated ADC (unlike MSP430F5172), and compatibility with TI's MSP430F51x1 family toolchain and firmware libraries.
Technical Context
The MSP430F5171IYFFR implements the CPUXV2 core with constant generators for optimized code density and executes instructions in 40 ns. Its unified clock system integrates FLL-based frequency stabilization, VLO (10 kHz), REFO (32.768 kHz), and support for external crystals up to 25 MHz on XT1.
Power management includes a programmable LDO for core voltage regulation, SVM/SVS monitoring, brownout reset, and five low-power modes - including LPM4.5 with 0.25 µA shutdown current and wake-up in <5 µs. The port mapping controller enables flexible peripheral-to-pin assignment across all I/O ports (P1–P3, PJ).

FAQ
What is the maximum operating frequency of the MSP430F5171IYFFR?
The MSP430F5171IYFFR supports a maximum system clock (MCLK) frequency of 25 MHz using the high-frequency crystal oscillator (XT1). Its CPUXV2 core executes instructions at 40-ns intervals, enabling deterministic real-time performance for time-critical control loops without overclocking risk.
Does the MSP430F5171IYFFR include an analog-to-digital converter (ADC)?
No, the MSP430F5171IYFFR does not include an integrated ADC. Unlike the MSP430F5172IYFFR, which features a 10-bit ADC10_A module, the MSP430F5171IYFFR is part of the F51x1 family that omits the ADC to reduce cost and power for purely digital control applications.
Which development tools support the MSP430F5171IYFFR?
The MSP430F5171IYFFR is supported by TI's MSP430Ware software library, Code Composer Studio IDE, and the MSP-FET programmer/debugger. Hardware evaluation is possible using the MSP-TS430RGC64 target socket board, which accommodates the 40-pin YFF package and provides access to all signals for prototyping.
What is the purpose of the VCORE pin on the MSP430F5171IYFFR?
VCORE is the output pin of the on-chip low-dropout regulator (LDO) that supplies the regulated core voltage (~1.8 V) to the CPU, RAM, and digital logic. It eliminates the need for an external core regulator, simplifying power design and improving efficiency in battery-operated systems using the MSP430F5171IYFFR.
Can the MSP430F5171IYFFR operate from a single 3.3-V supply?
Yes, the MSP430F5171IYFFR operates across 1.8 V to 3.6 V, making 3.3 V a fully supported and commonly used supply voltage. At 3.3 V, it delivers 180 µA/MHz active current and maintains full peripheral functionality including 20-mA I/O drive strength and stable 25-MHz XT1 operation.
