The use scenario of the smart water meter determines that the internal battery must be used for power supply, and the industry requires the working life of the water meter to reach 6 years or more. This imposes stringent requirements on the overall power consumption of the water meter. Taking the reed pipe metering water meter as an example, the capacity of a typical 18505 battery is 3500 mAh. To ensure that the water meter working time is longer than 6 years, the average power consumption current index of the entire meter must be controlled within 10 μA to be qualified.
Reducing the power consumption of water meters at all stages of the work life cycle is an urgent problem to be solved by designers. In the smart three-table IC innovation technology seminar, Yu Xianwei, external relations manager of China National Semiconductor’s MCU Division, takes The intelligent prepayment (RF card) reed pipe metering method is used as an example, and we thoroughly discuss the realization of the ultra-low power consumption of the water meter as a whole.
Huada Semiconductor's ultra-low-power MCU chip provides a flexible and versatile set of nine operating mode switching, with a 0.9μA domestic minimum power consumption level. Through on-site measurement, the water meter integrated with this MCU chip demonstrates that the overall current work under full-time working condition is controlled below 1 mA; at low frequency 32.768 Hz, the overall current is about 10 mA; when it enters full power saving mode, the overall current energy Less than 4μA, its low-power performance is widely recognized by industry customers. Huada Semiconductor will focus on the layout of smart hardware and IoT technologies.
