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. ## Lifecycle and supply position 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.
