Renesas: RL78/I1C MCUs support DLMS standard for smart meters
Renesas Electronics Europe announced the availability of its new microcontrollers for the power meter market, particularly targeting the smart meters. The new RL78/I1C Group of MCUs is designed for the international standard DLMS with enhanced security function and improved arithmetic operation. The RL78/I1C Group of MCUs also retains the measurement accuracy and low power consumption of its predecessor, the RL78/I1B Group, of which more than 30 million units have been shipped over a period of three years.
The new RL78/I1C MCUs are available in seven versions, with on-chip memory capacities ranging from 64 KB for low-end single-phase meters, 128 KB for high-end single-phase meters, and 256 KB for three-phase meters; and package pin counts from 64 pins for space-saving needs, 80 pins for single-phase meters aimed for use in emerging countries, to 100 pins for single-phase meters aimed for use in advanced applications.
By using the evaluation kit in the initial study phase, it is possible to start evaluating performance characteristics of the RL78/I1C without actually writing programs. The reference kit, which includes hardware and drivers for measurement functions as well as a highly reliable DLMS library, can be used in the meter development phase to reduce the time required for development by approximately 25 percent, compared with independent development, and also to reduce costs.
