SY7T609+R1 - Energy Measurement Processor with Integrated Oscillator & Relay Control


  • High resolution delta-sigma ADC with two analog (sensor) inputs
  • Precision internal voltage and timing references minimize external components
  • 24-bit energy measurement processor with nonvolatile storage of calibration and configuration data
  • Flexible SPI or UART interface options with user configurable DIO
  • Relay Control
  • Small 14-pin TSSOP package


The SY7T609+R1 is an energy measurement processor (EMP) designed for monitoring and relay control of any 2-wire AC (or DC) circuit. With an integrated oscillator and small profile, it is ideally suited for BOM optimized applications such as smart-plugs, smart appliances, lighting and building automation. SPI and UART interface options are supported. An optimized protocol for low baud rate UART communications further reduces the BOM cost when data isolation is required.
