It targets battery-powered sensor systems and digital power supplies requiring sub-µA standby current.
For engineers reviewing the MSP430F5172IDA datasheet, MSP430F5172IDA pinout, MSP430F5172IDA application, or MSP430F5172IDA equivalent, key selection criteria include LPM3 current (1.1 µA), 5-V-tolerant I/O count (12 pins), ADC resolution and sampling rate, Timer_D high-resolution mode support, and TSSOP-38 package compatibility with legacy board layouts.
Technical Context
The MSP430F5172IDA implements a 16-bit RISC CPUXV2 core with constant generators and 40-ns instruction cycle time, paired with a unified clock system including FLL-stabilized DCO, VLO, REFO, and XT1 support for 32-kHz to 25-MHz crystals. Its power management integrates a programmable LDO, SVM/SVS monitoring, and brownout detection.
Peripherals include two independent 16-bit Timer_D modules (TD0/TD1) each with three capture/compare registers and high-resolution mode, one 16-bit Timer_A (TA0), 3-channel DMA, hardware multiplier supporting 32-bit operations, and dual USCI modules-USCI_A0 for UART/IrDA/SPI and USCI_B0 for I²C/SPI-enabling flexible serial communication in low-power designs.

FAQ
What is the maximum operating frequency of the MSP430F5172IDA?
The MSP430F5172IDA supports a maximum system clock (MCLK) frequency of 25 MHz when using an external high-frequency crystal (XT1). Its digitally controlled oscillator (DCO) is FLL-stabilized and configurable across multiple ranges, enabling reliable operation up to 25 MHz under recommended conditions (3.6 V to 1.8 V supply, ambient temperature –40°C to 85°C). This frequency capability is fully supported in the 38-pin TSSOP package.
Does the MSP430F5172IDA support hardware debugging without external tools?
Yes, the MSP430F5172IDA integrates Spy-Bi-Wire (SBW) debug interface on dedicated pins (RST/NMI/SBWTDIO and TEST/SBWTCK), enabling full JTAG-like functionality-including breakpoint setting, register inspection, and flash programming-using only two wires. No external debug probe is required beyond a standard SBW-capable programmer, and the interface remains functional even in ultra-low-power modes.
How many analog input channels does the MSP430F5172IDA ADC support?
The MSP430F5172IDA features a 10-bit ADC10_A module supporting up to 8 external analog input channels (A0–A5, plus two additional pins mapped to A6/A7/A8 depending on package) and 2 internal channels (temperature sensor and reference voltage). This configuration is confirmed for the MSP430F51x2 family and applies specifically to the MSP430F5172IDA in its 38-pin TSSOP variant.
Is the MSP430F5172IDA pin-compatible with other devices in the MSP430F51x2 family?
Yes, the MSP430F5172IDA shares identical pinout, signal mapping, and package dimensions with MSP430F5152IDA and MSP430F5132IDA in the 38-pin TSSOP (DA) package. All three devices have the same 38-pin layout, I/O assignment, power/ground pin locations, and debug interface placement-enabling direct replacement within the same footprint without PCB modification.
What is the wake-up time from LPM3 standby mode for the MSP430F5172IDA?
The MSP430F5172IDA wakes up from LPM3 (standby mode with watchdog timer active) in less than 5 µs, as specified in the official datasheet SLAS619R. This rapid wake-up is achieved via the FLL-stabilized DCO and applies across all supported supply voltages (1.8 V to 3.6 V) and temperature ranges (–40°C to 85°C), making it suitable for event-driven sensor sampling with minimal latency.
