They allow simultaneous sampling of voltage and current on three phases in a polyphase energy meter, with enough resolution to meet IEC 62053 class 0.5 accuracy without an external AFE. The 16-bit core handles the compute load for active/reactive power calculation, harmonic analysis, and tamper detection, while the DMA moves conversion results without CPU intervention. The MSP430F6766IPEUR is officially marked Obsolete by Texas Instruments. There is no direct pin-compatible replacement announced by TI for this exact order code, but the MSP430F6xx family includes other 128-pin devices with similar sigma-delta ADC blocks — a design review is needed to confirm peripheral and memory match before substituting. ## Package and temperature — board-fit checks The device comes in a 128-LQFP package (20x14 mm body) with a 0.4 mm pitch — a standard footprint for industrial metering boards, but the fine pitch means the PCB fab needs a Class 3 solder mask registration for reliable assembly.","metaTitle":"TI MSP430F6766IPEUR 16-bit MCU, 25MHz, 256KB Flash","metaDescription":"Texas Instruments MSP430F6766IPEUR 16-bit MCU with 25MHz core, 256KB Flash, 16KB RAM, 6x24-bit sigma-delta ADC.
