Product details
Overview
MSP430F5171IYFFT from Texas Instruments is an ultra-low-power 16-bit RISC microcontroller 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), 5-V-tolerant I/Os, and a 16-channel comparator. It operates from 1.8 V to 3.6 V and supports LPM4.5 shutdown mode at 0.25 µA (3 V), targeting battery-powered sensor nodes and portable metering.
For engineers reviewing the MSP430F5171IYFFT datasheet, MSP430F5171IYFFT pinout, MSP430F5171IYFFT application, or MSP430F5171IYFFT equivalent, key selection criteria include its DSBGA-40 package, absence of integrated ADC (unlike MSP430F5172), 29 GPIOs with configurable port mapping, and compatibility with TI's MSP430F51x1 family toolchain and firmware libraries.
Technical Context
The MSP430F5171IYFFT 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 via XT1.
Power management includes a programmable LDO core regulator, supply voltage supervision (SVM/SVS), brownout reset, and five low-power modes-LPM0–LPM4-with wake-up from LPM3 in <5 µs. The 3-channel DMA engine enables efficient peripheral-to-memory transfers without CPU intervention.

FAQ
Does MSP430F5171IYFFT include an integrated analog-to-digital converter (ADC)?
No, the MSP430F5171IYFFT does not integrate an ADC. Unlike the MSP430F5172IYFFT, which includes a 10-bit ADC10_A module, the MSP430F5171IYFFT omits this peripheral. Designers requiring analog signal conversion must use external ADCs or select the MSP430F5172IYFFT variant. This omission reduces die size and cost while preserving all other timing, communication, and low-power capabilities of the MSP430F5171IYFFT.
What is the package type and footprint of MSP430F5171IYFFT?
The MSP430F5171IYFFT uses a 40-ball DSBGA (Die-Sized Ball Grid Array) package designated YFF, measuring 2.1 mm × 2.1 mm with 0.4 mm ball pitch. It features separate DVIO, DVCC, DVSS, AVCC, and AVSS power domains, and includes dedicated test pins (RST/NMI/SBWTDIO and TEST/SBWTCK) for programming and debug. This compact package supports high-density PCB layouts typical in space-constrained portable electronics.
How many GPIOs does MSP430F5171IYFFT support, and are they 5-V tolerant?
The MSP430F5171IYFFT provides 29 general-purpose I/O pins, all 5-V tolerant when powered by the DVIO rail (1.8–3.6 V). These include P1.x (8 pins), P2.x (8 pins), P3.x (8 pins), PJ.x (7 pins), and support configurable pullup/pulldown resistors and interrupt capability. This tolerance allows direct interfacing with legacy 5-V logic, sensors, and displays without external level-shifting circuitry, reducing BOM count and board area.
What low-power modes are supported by MSP430F5171IYFFT, and what is the lowest current draw?
The MSP430F5171IYFFT supports five low-power modes (LPM0–LPM4) plus LPM4.5. In LPM4.5 (shutdown mode with RAM retention), it draws just 0.25 µA at 3 V. This mode disables the LDO, stops all clocks, and retains only SRAM contents-ideal for long-term storage of configuration or state during extended standby. Wake-up is triggered exclusively by RST/NMI or specific I/O interrupts, ensuring deterministic recovery.
Is MSP430F5171IYFFT pin-compatible with other devices in the MSP430F51x1 family?
Yes, the MSP430F5171IYFFT is pin-compatible with other YFF-package variants in the MSP430F51x1 family-including MSP430F5151IYFFT and MSP430F5131IYFFT-as well as the MSP430F51x2 series (e.g., MSP430F5172IYFFT) in the same 40-pin DSBGA footprint. Pin functions, power domains, and mechanical dimensions match exactly, enabling drop-in replacement for memory or peripheral scaling without PCB revision.
