TIDM-SINGLEPHASEMETER-FE4272, Single-Phase Energy Meter with CPU-Independent Metrology Engine. This single-chip electric meter solution implements a single-phase e-meter utilizing the MSP430FE4272 SoC and TPS77033 LDO regulator. It utilizes the CPU-independent ESP430 Metrology Engine to perform all of the required e-meter calculations with no impact on the main MCU core. This allows the developer to add other functions into the SoC, reducing overall e-meter BOM cost. With this tool developers can quickly determine that the FE4272 e-meter SoC fits the requirements for their low-cost smart e-meter
