Description CJMCU CS5460A Single Phase, Two Way Serial Energy Metering Module is developed based on CS5460A IC, which is a single phase, two channels (one Chanel for current and one channel for voltage) power/energy IC. The IC is a fully integrated power measurement utility which combines two ADCs (Analog-to-Digital Converters), high-speed power calculation functions, and a serial interface on a single chip. It measures and calculates the quantity of Real Energy, Instantaneous Power, IRMS, and VRMS for single phase 2-wire or 3-wire power metering devices. For measuring current, the CS5460A module interfaces to a cheap shunt resistor or transformer, and interfaces to a resistive divider or potential transformer for measuring voltage. This module applies a bi-directional serial interface for connection with a micro-controller and a pulse output engine for which the average pulse frequency is proportional to the real power. The module has on-chip functionality to facilitate AC or DC system-level calibration, conveniently. It has a smart “Auto-boot” Mode, which enables it initializes itself on system power-up and works without micro-controller. On self-boot Mode, the CS5460A reads the calibration data and start-up instructions from an external EEPROM. By applying it in this mode, the CS5460A can operate without a micro-controller, therefore designer can reduce the total cost, because of the BOM reduction part.
