This combination targets battery-powered instrumentation, sensor hubs, and industrial control nodes where the 16-bit RISC architecture delivers deterministic interrupt response and sub-µA standby currents.
Housed in a 38-TSSOP (6.10 mm body width), the part is a surface-mount device. The supplier device package is 38-TSSOP.
Within the MSP430F5xx family, pin-compatible Flash and RAM density variants exist (e.g., MSP430F5131, MSP430F5151), but the exact peripheral set and memory map differ. No official second-source cross-reference is listed. For a drop-in replacement, verify the specific memory and peripheral requirements against the target variant's datasheet.
Yes — the MSP430F5171IDA uses the standard Spy-Bi-Wire (SBW) or JTAG interface common to all MSP430 devices. Any MSP430 programmer (e.g., TI MSP-FET, eZ-FET) supports it. The 32 KB Flash is in-system programmable via the bootloader or debug tool.
