Product details
Overview
MSP430F5172IYFFT from Texas Instruments is a 16-bit ultra-low-power mixed-signal 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), 10-bit 200-ksps ADC with 8 external + 2 internal channels, and 16-channel comparator. It operates from 1.8 V to 3.6 V and targets battery-powered sensor systems requiring sub-µA standby current.
For engineers reviewing the MSP430F5172IYFFT datasheet, MSP430F5172IYFFT pinout, MSP430F5172IYFFT application, or MSP430F5172IYFFT equivalent, this page delivers verified technical context, package-specific pin mapping, real-world use cases, and validated alternative options for low-power embedded design.
Technical Context
The MSP430F5172IYFFT implements the CPUXV2 core with 16-bit RISC architecture and 40-ns instruction cycle time. Its unified clock system integrates FLL stabilization, VLO (10 kHz), REFO (32.768 kHz), and support for 32-kHz crystals (XT1) and up to 25-MHz high-frequency crystals.
It includes a programmable LDO for core voltage regulation, supply supervision with brownout detection, and three low-power modes (LPM3: 1.1 µA at 3 V; LPM4: 0.9 µA RAM retention; LPM4.5: 0.25 µA shutdown). The 3-channel DMA enables autonomous peripheral data movement without CPU intervention.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430F5152IYFFT | 16 KB Flash, 2 KB RAM, identical peripherals and pinout - no ADC internal channels or temperature sensor | Lower memory requirement; suitable for UART/I²C gateway-only roles without local analog processing | Select when firmware size ≤16 KB and no on-die temperature measurement is needed |
| MSP430F5132IYFFT | 8 KB Flash, 1 KB RAM, same peripheral set but reduced memory and no ADC internal channels | Cost-sensitive, minimal-feature implementations (e.g., simple sensor polling + UART relay) | Choose for high-volume, memory-light applications where ADC channel count and Flash headroom are not constraints |
Compared with MSP430F5172IYFFT, the MSP430F5152IYFFT and MSP430F5132IYFFT retain identical low-power operation, timer capabilities, and DSBGA packaging but scale down Flash/RAM and omit internal ADC channels-making them viable for streamlined firmware deployments where full 32 KB capacity is unnecessary.

FAQ
What is the maximum operating frequency of the MSP430F5172IYFFT?
The MSP430F5172IYFFT supports a maximum system clock (MCLK) of 25 MHz using an external crystal on XT1. Its CPUXV2 core achieves a 40-ns instruction cycle time, enabling deterministic real-time execution at up to 25 MIPS. Internal DCO and FLL allow stable frequency synthesis without external components for lower-frequency applications.
Does the MSP430F5172IYFFT include an internal temperature sensor?
Yes, the MSP430F5172IYFFT includes an internal temperature sensor connected to ADC10_A channel A10. This sensor is factory-calibrated and usable across the full operating range (–40°C to 85°C), enabling accurate thermal monitoring without external components. It is explicitly documented in the device family datasheet as available only on MSP430F51x2 variants.
Is the MSP430F5172IYFFT pin-compatible with other packages in the F51x2 family?
No - the MSP430F5172IYFFT uses a 40-pin DSBGA (YFF) package with unique ball map and power domain layout (DVIO, VCORE, AVCC). It is not pin-compatible with the 40-pin WQFN (RSB) or 38-pin TSSOP (DA) variants, though all share identical signal functionality and register-level compatibility. Layout redesign is required when switching packages.
What debug interface does the MSP430F5172IYFFT support?
The MSP430F5172IYFFT supports Spy-Bi-Wire (SBW) debug via RST/NMI/SBWTDIO and TEST/SBWTCK pins - a two-wire interface compatible with TI's MSP-FET and LaunchPad debuggers. It does not support full 4-wire JTAG. SBW enables flash programming, breakpoint debugging, and real-time register inspection with minimal PCB footprint.
Can the MSP430F5172IYFFT operate from a single 3.3-V supply?
Yes - the MSP430F5172IYFFT operates across 1.8 V to 3.6 V. At 3.3 V, it delivers full performance: 25-MHz MCLK capability, 20-mA I/O drive strength, and specified ADC accuracy. Its integrated LDO regulates VCORE independently, ensuring stable core voltage even with modest DVCC ripple or droop during transient loads.
