The MSP430F677x family is designed for high-accuracy revenue meters. These devices integrate a powerful 16-bit RISC CPU with specific peripherals optimized for measuring electrical energy consumption across multiple phases. Key Technical Specifications
: Engineered for ultra-low power consumption, allowing for smaller system power supplies and longer data retention during power failures. Core Applications
: Features 24-bit sigma-delta analog-to-digital converters (ADCs) that provide better than 0.1% accuracy for energy measurement. Memory : Offers up to 512KB of Flash memory and 32KB of RAM .
: Used by utility companies to accurately track electricity usage in three-phase systems.
: Supports communication modules for AMR (Automated Meter Reading) and AMI (Advanced Metering Infrastructure).
: Detailed Instruction Set Reference Guides are available to help program the DSP and CPU architecture.
: Capable of managing different billing rates based on time-of-use or other criteria. Development Resources
: A graphical user interface (GUI) and software library for developing sensing and measurement applications.
