Each ADC pair (one voltage, one current per phase) samples simultaneously, so the phase angle between voltage and current is captured in the same instant — no external sample-and-hold or multi-chip synchronisation needed. For a three-phase meter, this eliminates the per-phase ADC and the isolation amplifier that a discrete front end would require, collapsing the analog BOM to a resistor divider and a current-sense transformer per phase. The 32 KB of RAM is the practical ceiling for buffering polyphase metrology data and LCD frame storage. With six channels streaming 24-bit samples, the firmware engineer needs to budget the sample buffer size against the available RAM — 8 KB per channel would exceed the total, so the metrology loop must process and decimate in real time rather than batch-store raw samples. ## On-chip peripherals — LCD driver, DMA, brown-out detect Beyond the ADC bank, the peripheral set includes a brown-out detect and reset, DMA controller, LCD driver, POR, PWM timer, and watchdog timer. The DMA can move ADC conversion results directly to RAM without CPU intervention — useful when the metrology loop must keep the sigma-delta channels fed while the CPU handles communication stacks or display updates.","metaTitle":"TI MSP430F67671AIPZR 16-bit MCU, 25MHz, 256KB Flash, 6x24b SD ADC","metaDescription":"Texas Instruments MSP430F67671AIPZR 16-bit MCU with 25MHz MSP430 CPUXV2, 256KB Flash, 32KB RAM, 6x24-bit sigma-delta ADCs.

Availability and current pricing are confirmed at quote time — no stock or price figures are published for an end-of-life part. Submit an RFQ for a current availability check and volume quote."},{"question":"What is MSP430F67671AIPZR's core speed?","answer":"The MSP430 CPUXV2 core runs at 25 MHz. That clock rate determines the instruction throughput for the metrology loop — at 25 MHz, the CPU has roughly 40 ns per instruction cycle to process each sigma-delta sample before the next conversion completes."},{"question":"What compliance documentation does TI provide for MSP430F67671AIPZR?","answer":"Texas Instruments provides RoHS and REACH compliance documentation for this part. The 100-LQFP package is lead-free and halogen-free per TI's standard material declarations. No UL or IEC certification is listed for this component — those certifications typically apply to the end equipment, not the IC itself."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/MSP430F67671AIPZR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/MSP430F67671AIPZR when reusing this data.
