Product details
Overview
MSP430F5172IYFFR 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 MSP430F5172IYFFR datasheet, MSP430F5172IYFFR pinout, MSP430F5172IYFFR application, or MSP430F5172IYFFR equivalent, this page delivers verified functional specifications, package-specific terminal mapping for the 40-pin DSBGA (YFF), low-power mode timing, ADC channel allocation, and validated alternative options for migration or second sourcing.
Technical Context
The MSP430F5172IYFFR implements the CPUXV2 core with 16-bit RISC architecture and 40-ns instruction cycle time. Its unified clock system integrates FLL-based frequency stabilization, VLO (10 kHz), REFO (32.768 kHz), and support for 32-kHz crystals (XT1) and up to 25-MHz high-frequency crystals - all configurable via software-controlled port mapping.
Power management includes an integrated LDO with programmable core voltage, supply supervision (SVM/SVS), brownout reset, and five low-power modes (LPM0–LPM4.5). Wake-up from LPM3 occurs in under 5 µs, and the device supports serial onboard programming without external voltage.

FAQ
What is the maximum operating frequency of the MSP430F5172IYFFR?
The MSP430F5172IYFFR supports a maximum system clock (MCLK) frequency of 25 MHz when using an external crystal oscillator (XT1 in high-frequency mode). The internal DCO can be calibrated to achieve stable operation up to 25 MHz, and the FLL loop ensures frequency stability across voltage and temperature variations - enabling deterministic real-time execution for time-critical sensor tasks.
Does the MSP430F5172IYFFR support hardware debugging after programming?
Yes, the MSP430F5172IYFFR supports full hardware debugging via the Spy-Bi-Wire (SBW) interface using the RST/NMI/SBWTDIO and TEST/SBWTCK pins. This allows non-intrusive breakpoints, register inspection, and flash programming without requiring a JTAG header - critical for field firmware updates and validation of battery-powered deployments.
How many ADC input channels are accessible on the MSP430F5172IYFFR in the YFF package?
The MSP430F5172IYFFR provides access to all 8 external ADC input channels (A0–A5, A7, A8) and both internal channels (temperature sensor and VREF) in the 40-pin DSBGA (YFF) package. Pin assignments match Table 4-1 in the datasheet, with A0–A5 mapped to P1.0–P1.5 and A7/A8 on P3.6/P3.5 - enabling full analog sensing capability without package-dependent channel reduction.
Can the MSP430F5172IYFFR operate from a single 3.3-V supply without external regulators?
Yes, the MSP430F5172IYFFR operates from a single 3.3-V supply applied to DVCC and AVCC. Its integrated LDO regulates the core voltage (VCORE) internally, and DVIO can be tied to DVCC for 3.3-V I/O operation. No external regulator is needed - simplifying power design for compact, low-component-count applications like wireless sensor tags.
Is the MSP430F5172IYFFR pin-compatible with other packages in the MSP430F51x2 family?
No, the MSP430F5172IYFFR (40-pin DSBGA) is not pin-compatible with the 40-pin WQFN (RSB) or 38-pin TSSOP (DA) variants. While signal functionality is identical across packages, ball/pad locations differ significantly - especially for power (DVIO, VCORE), analog (AVCC/AVSS), and peripheral (XIN/XOUT) pins. PCB layout must be redesigned for each package option.
