MQX-Enabled MCF51EM256 Single-Phase Electricity Meter Reference Design
A single-phase electricity meter reference design using the NXP MCF51EM256 MCU, featuring ZigBee connectivity, anti-tamper detection, and MQX RTOS integration.
Overview
This reference design manual (DRM121) provides a comprehensive solution for a high-performance single-phase two-wire electricity meter. Based on the NXP MCF51EM256 microcontroller, the design incorporates the MC1322x low power node for ZigBee smart grid connectivity and the MMA7660FC 3-axis Xtrinsic accelerometer for tamper detection. The system is built on the MQX real-time operating system to support advanced power measurement algorithms and features a 5(100)A current range. Hardware implementation details include signal conditioning for voltage and current (shunt or CT), RS232 and infrared (IEC1107) interfaces, and HMI components like an LCD and user buttons.
Use Cases
- Residential electricity metering
- Smart grid network integration
- Automated Meter Reading (AMR) systems
- Anti-tamper energy monitoring solutions
