Product details

What this 16-bit MCU brings to a metering or sensor front-end

The MSP430F67471AIPEUR: Its standout feature is the four 24-bit sigma-delta ADCs — these are not general-purpose converters; they are designed for precision measurement in energy metering, flow sensing, and weigh-scale applications where you need high-resolution low-frequency data without an external analog front-end. The 256KB Flash and 32K x 8 RAM give enough headroom for metrology algorithms and logging buffers, while the 90 I/Os handle display interfaces, keypads, and communication links.

Peripheral set and connectivity for industrial panels

Temperature grade and package — board-fit notes

The supplier device package is 128-LQFP (20x14).

No near-term EOL risk, no last-time-buy pressure. If you are stocking for a long-production run, this is a safe SKU to qualify.

Frequently asked questions

What is the difference between MSP430F67471AIPEUR and MSP430F67471?

The MSP430F67471AIPEUR is the Tape & Reel (TR) packaged variant of the base MSP430F67471. The silicon, core, memory, and peripheral set are identical. The TR suffix means it ships on a reel for automated pick-and-place assembly, not in trays or tubes. If your line runs reel-fed feeders, this is the correct ordering code.

What is the role of the sigma-delta converter in MSP430F67471AIPEUR?

The four 24-bit sigma-delta ADCs are the primary analog acquisition path. They are designed for low-bandwidth, high-resolution measurements — think voltage and current sensing in energy meters, strain-gauge bridges in weigh scales, or temperature/pressure transducers in industrial transmitters. The sigma-delta architecture oversamples and shapes quantization noise out of the band of interest, giving you 24-bit resolution at update rates in the tens to hundreds of samples per second.

Is MSP430F67471AIPEUR suitable for battery-powered applications?

Yes, the MSP430 family is known for ultra-low-power operation. The CPUXV2 core and multiple low-power modes (LPM0 through LPM4) let you drop the active current to microamps in standby. The sigma-delta converters can operate in low-power mode, making this a strong candidate for battery-powered metering or data-logging nodes.
