Its defining peripheral set — four 24-bit sigma-delta ADCs, an LCD driver, and a 10-bit SAR ADC — targets polyphase energy metering and industrial instrumentation where multiple high-resolution analog channels must be digitised simultaneously and displayed locally. The 25 MHz CPU clock drives the four 24-bit sigma-delta modulators. The internal oscillator provides the timing. ## Active lifecycle — no LTB flag, but monitor PCNs TI lists the MSP430F67481AIPEU as Active. That means it is still a valid BOM line for new production and field spares. The MSP430F6xx family is mature, so while there is no imminent last-time-buy, a sourcing buyer should watch for package-migration or wafer-fab PCNs that could affect long-term form-fit-function continuity. ## Package and pinout — 128-LQFP (20×14 mm) The 128-LQFP has a 20×14 mm body.","metaTitle":"TI MSP430F67481AIPEU 16-bit MCU, 25MHz, 256KB Flash, 4×24b SD ADC","metaDescription":"Texas Instruments MSP430F67481AIPEU 16-bit MCU with MSP430 CPUXV2 at 25MHz, 256KB Flash, 32KB RAM, 4×24b sigma-delta ADC, LCD driver, 90 I/O, 1.8-3.6V, -40 to 85°C, 128-LQFP.
