摘要
采用So C方案设计了一款高准确度、低成本、低功耗的单相智能电能表。该电能表采用So C芯片HT5017作为控制核心。HT5017是一颗低功耗、高性能的单相电能计量So C芯片,片内集成了32-bit ARM内核、128 K flash和8 K SRAM,其支持断相防窃电功能的硬件EMU模块,带有温度自补偿功能的高准确度RTC模块以及LCD驱动器。该设计为单相多功能、防窃电电能表提供了高集成的单芯片解决方案。小批生产结果表明,所设计的电表完全满足海外客户的技术要求,具有广泛的市场推广价值。
A high-precision, low-cost, low-power single-phase smart electric energy meter is designed by adopting SoC chip HT5017 as acontrol core. HT5017 is a low-power, high-performance single-phase energy metering SoC chip, in which 32-bit ARM core, 128 K flash and8K SRAM are integrated, which supports hardware EMU module withopen-phase anti-tamper features and high-precision RTC module withtemperature compensation functions, as well as LCD drivers. The designprovides a highly integrated single-chip solution for single-phase, multifunctional,anti-tampering electric energy meter. Results of small batch production show that the single-phase smart electric energy meter could completely meet the technical requirements of overseas customers with a wide range of marketing value.
