2 / 20 page REV. 0 –2– ADSST-EM-2030 PIN FUNCTION DESCRIPTION Pin No. Mnemonic Description 1 DGND Digital Ground 2DLOAD Used to Enable Serial Download of Program Memory 3GAIN 1 Logic Channels Output for Multiplexer to Switch Gain for A-Phase Current 4GAIN 2 Logic Channels Output for Multiplexer to Switch Gain for B-Phase Current 5 TAMP Logic Output Indicating that One More Current Is Reversed 6CFCalibration Frequency Logic Output. This gives instantaneous real power information and can be used for calibration. 7GAIN 3 Logic Channels Output for Multiplexer to Switch Gain for C-Phase Current 8, 9 F1, F2 Low Frequency Logic Outputs. F1 and F2 provide average real power information. The logic outputs can be used to drive electromechanical counters and 2-phase stepper motors. 10 RESET System Reset 11 APHV A-Phase Voltage Input 12 APHC A-Phase Current Input 13 AVDD Analog Positive Supply 14 AGND Analog Ground 15 AGND Analog Ground 16 VREF Input for External Voltage Reference PIN CONFIGURATION DLOAD GAIN 1 GAIN 2 TAMP CF GAIN 3 SS MISO MOSI SCLK F1 F2 XTAL2 XTAL1 RESET AVDD AGND AGND DGND DVDD VREF CREF CPHC CPHV BPHC BPHV APHC APHV CAUTION ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the human body and test equipment and can discharge without detection. Although the ADSST- EM-2030 features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality. ORDERING GUIDE Model Temperature Package Package Range Description Option ADSST-EM-2030 –40 °C to +85°C Tiny Shrink RU–28 Small Outline Package PIN FUNCTION DESCRIPTION (continued) Pin No. Mnemonic Description 17 CREF Filter Capacitor for Reference 18 BPHV B-Phase Voltage Input 19 BPHC B-Phase Current Input 20 CPHV C-Phase Voltage Input 21 CPHC C-Phase Current Input 22 SS This Logic Signal conveys to ADSST- EM-2030 that data transfer on SPI is requested. 23 MISO Data Output on SPI from ADSST-EM-2030 24 MOSI 25 SCLK Clock for SPI. This clock is generated by an external microcontroller when the data transfer to or from ADSST- EM-2030 takes place. 26 XTAL1 Crystal Oscillator 27 XTAL2 Crystal Oscillator 28 DVDD Digital Positive Supply |
