The standout feature is the integrated 7×24-bit sigma-delta ADC array — this is a metrology-grade measurement front end designed for polyphase energy meters, power-quality monitors, and multi-channel industrial sensor acquisition. Supporting peripherals include an 8×10-bit auxiliary ADC, a DMA controller, an LCD driver, a brown-out detect/reset circuit, a POR, a PWM, and a watchdog timer. The device operates from 1.8 V to 3.6 V over the industrial temperature range of –40 °C to 85 °C, and is supplied in a 128-LQFP package (20×14 mm). ## What the 7×24-bit sigma-delta converter means for your design Seven simultaneous 24-bit sigma-delta channels let this single MCU handle three-phase voltage and current sensing plus neutral — no external ADC or analog front-end chip needed. The 24-bit resolution gives the dynamic range to resolve small load currents alongside full-scale line inputs without gain switching. For a polyphase meter, that means one BOM line replaces a multi-chip metrology AFE plus a separate MCU. The 8×10-bit auxiliary ADC handles the temperature sensor or tamper-detection channel without stealing a sigma-delta channel. However, some channel records flag an end-of-life-hot designation, which suggests the part may be approaching a last-time-buy phase. No official successor order code is published. ## Industrial temperature and 128-LQFP package The 128-LQFP (20×14 mm) is a standard fine-pitch surface-mount package.","metaTitle":"TI MSP430F6777AIPEU 16-bit MCU, 25MHz, 256KB Flash, 7x24-bit SD ADC","metaDescription":"Texas Instruments MSP430F6777AIPEU MSP430F6xx 16-bit MCU with 25MHz CPUXV2 core, 256KB Flash, 32KB RAM, 7×24-bit sigma-delta ADC, 90 I/O, -40°C to 85°C, 128-LQFP.
