The 25 MHz core has enough headroom to run the metrology algorithms and communication stacks without a second processor. ## Memory and peripheral mix for a metering BOM The integrated LCD driver eliminates a separate display controller, and the DMA engine moves ADC results to RAM without CPU intervention. Brown-out reset and POR are on-chip, reducing external supervisor IC count. That means no end-of-life notice is in effect, and the part is still supported for new design-ins. For production planning, this removes the single-source urgency that comes with NRND or obsolete parts — though as with any active IC, lead-time variability can tighten during allocation cycles. We source through franchised and independent channels and confirm availability at quote time.","metaTitle":"TI MSP430F67661AIPZR 16-bit MCU, 25MHz, 256KB Flash","metaDescription":"Texas Instruments MSP430F67661AIPZR 16-bit MCU with 25MHz core, 256KB Flash, 16KB RAM, 6x24-bit sigma-delta ADC, 100-LQFP.

The MSP430 architecture is designed for low-power operation, with multiple sleep modes and a 1.8 V minimum supply. The 25 MHz core is active only when needed, and the sigma-delta ADC can run autonomously with the DMA moving results to RAM while the CPU sleeps. For battery-powered or energy-harvesting metering designs, the part is a strong fit."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/MSP430F67661AIPZR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/MSP430F67661AIPZR when reusing this data.
