RL78/I1C is an ultra-low power microcontroller for the high-end smart electricity meter market. It integrates the functions required for the metrology of smart electricity meters. It includes 24bit ΔΣ A/D converters, 32bit Multiply-accumulator, an Independent power supply a real-time clock, a segment LCD driver supporting up to 8 com, and an AES hardware engine that supports the DLMS standard. For single-phase, two-wire meters, single-phase three-wire meters, and three-phase three-wire meters, 24bit ΔΣ A/D converters (Max 4ch) are used for current and voltage sensing to achieve highly accurate power metrology.
