Renesas Semiconductor Single-Phase Smart Meter Solution

summary

Electricity meters are rapidly evolving into electronics as a need to prevent theft of electricity and automatic meter reading (AMR). In recent years, with the advancement of energy conservation and environmental protection, in order to realize a smart grid that uses energy efficiently at the local level, smart meters that control various indoor devices through electric meters are expanding in various places. The electric meter is becoming a gateway for home communication, and is moving toward high performance and high functionality.

The installation of the meter from the factory to the field requires the operation of a built-in battery, and only the low power consumption of the real-time clock (RTC) operation becomes more important. In addition, in order to satisfy the infrared communication at the time of AMR and table lookup, a UART (Universal Asynchronous Receiver Transmitter) is required for communication between prepaid cards.

The R8C/Lx series in the Renesas MCU product line has a built-in 3-channel UART to meet the various communication methods required for smart meters, and low power consumption through built-in RTC. In addition, the large-capacity memory can support the high functionality of smart meters. Other built-in on-chip oscillators (OCO), watchdog timers (WDTs), LCD drive control circuits, etc. reduce the number of external components, resulting in low cost.
