    Single-Phase Metering SoC
    V98XX is a high performance, low-power single-phase metering SoC chips which is gathered in AFE, energy metering architecture, enhanced 8052 MCU core, RTC, WDT, Flash, SRAM and LCD driver. It is commonly used to the single-phase multi-functional for energy meter applications.

    3.3V or 5V power supply, wideband voltage input range: 2.5V~5.5V
    Reference voltage: 1.185V (10ppm/℃)
    The typical operating current in full operation: 5.5mA
    Sleep mode (the typical operating mode): 10uA
    4 independent oversampling ∑-? ADCs: one voltage, two current, and 1 multi-functional channel. 
    Various measurements
    -  Raw waveforms and DC components of voltage/ current signals
    -  Instantaneous/ active/ reactive power average in sec and apparent power average in sec
    -  Instantaneous/voltage/ current average in sec RMS 
    -   Active/reactive energy power are selectable 
    High performance 8-bit 8052 MCU core with programmable operation 
    High performance RTC, support temperature sensor 
    Highly metering accuracy
    -  Less than 0.1% error in active energy metering over a dynamic range of 5000:1. 
    -  Less than 0.1% error in reactive energy metering over a dynamic range of 3000:1. 
    -  Less than 0.5% error in voltage/ current RMS metering over a dynamic range of 1000:1.
