They are designed for direct connection to current transformers and voltage dividers in three-phase energy meters, enabling simultaneous sampling of all phases plus neutral. The 24-bit resolution delivers the dynamic range needed to measure both idle current and full-load current from the same sensor without gain switching. ## Peripheral set and I/O for system integration With 90 I/O lines brought out to the 128-LQFP package, this MCU has enough pins to drive a segmented LCD directly (the peripheral set includes an LCD driver), read a keypad, control relays, and communicate over multiple serial buses simultaneously. The brown-out detect and power-on reset circuits are on-chip, reducing external supervisor IC count. The DMA controller offloads data movement between the sigma-delta converters and RAM without CPU intervention, preserving the 25 MHz core bandwidth for metrology calculations. For production BOMs, this means no forced redesign cycle from obsolescence in the near term.","metaTitle":"Texas Instruments MSP430F6766AIPEUR 16-bit MCU, 25 MHz","metaDescription":"Texas Instruments MSP430F6766AIPEUR 16-bit MCU with 6x24-bit sigma-delta ADC, 256 KB Flash, 16 KB RAM, 90 I/O, -40°C to 85°C.
