Renesas Electronics announced the availability of a full reference platform for the RX21A group of 32-bit microcontrollers (MCUs) for smart electricity meters with advanced functionality.
The platform comprises a full development support environment including middleware for power measurement and calibration tools. Key hardware features include a modular design supporting both 3-phase 4-wire and single-phase operation, and configurable sensor types including current transformer. This enables it to operate at nominal 230 V 50 Hz-60 Hz, with full 100 mA to 100 A measurement range. Accuracy is equivalent to IEC62053-22 (and ANSI C12.20), to at least class 0.5S, and compliant with IEC6205-23, class 2 reactive.
A full set of metrology libraries is provided, enabling precision measurement of voltage and current on each phase, active and reactive power on each phase, and apparent and harmonic power on each phase. Power quality measurement functions such as voltage sag are also provided.
Key software features include single point calibration for the 24-bit precision A-D converter (ADC) and analog front-end (AFE), and temperature compensation for the AFE including programmable gain amplifier and ADC, voltage reference and real-time clock.
Data exchange can be carried out via the IEC62056-21 (also known as IEC1107) optical port and isolated USB virtual COM port. A user-friendly, multifunction graphical display and an intuitive PC graphical user interface allow easy operation.
