Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VDD | power_in | Power supply input for 4.5V to 5.5V or 3.0V to 3.6V with internal brown-out detection at 2.9V power-on and 2.7V power-off thresholds. |
| 2 | V1P | input | Current channel A positive input of differential pair with 12MΩ equivalent input impedance and ±700mV differential range (PGA=1) for power and RMS measurements. |
| 3 | V1N | input | Current channel A negative input of differential pair paired with V1P for active power calculation and waveform sampling. |
| 4 | V2P | input | Current channel B positive input in differential configuration with selectable PGA gain 1/2/4/8/16 for power measurement or internal temperature sensor input. |
| 5 | V2N | input | Current channel B negative input of differential pair paired with V2P for dual-channel energy calculation and reactive power measurement. |
| 6 | V3P | input | Voltage channel positive input in differential configuration with ±700mV range at PGA=1 and 12MΩ input impedance for voltage RMS and frequency measurement. |
| 7 | GND | power_in | Chip ground and analog signal reference for all analog and digital circuits. |
| 8 | VREF | power_out | Internal 1.25V reference voltage output with ±1% accuracy and 5-15ppm/°C temperature coefficient over -40°C to +85°C operating range. |
| 9 | SDO/TX | output | SPI serial data output when SPIEN=1 and SCSN=0, UART TX output when SPIEN=0, or high-impedance when SCSN=1 with optional open-drain output mode via register. |
| 10 | SDI/RX | input | SPI serial data input when SPIEN=1 (up to 890kHz clock) or UART RX input when SPIEN=0 supporting 9600baud or 4800baud configuration. |
| 11 | SCLK | input | SPI serial clock input up to 890kHz when SPIEN=1, or UART baud rate selector (high=9600Hz, low=4800Hz) when SPIEN=0. |
| 12 | SCSN | input | SPI chip select input (active low to enable SPI) when SPIEN=1, or UART baud rate control signal when SPIEN=0. |
| 13 | SPIEN | input | Interface mode selector - set high for SPI mode (up to 890kHz) or low for UART mode (4800/9600 baud). |
| 14 | CLKI | input | External 3.579MHz oscillator input pin for crystal clock detection when sine wave signal applied, or internal oscillator mode when tied low. |
| 15 | CLKO/PULSE1 | output | External oscillator output when external clock applied to CLKI, or selectable digital function output for energy pulses (PFA/PFB), interrupts, and status signals via register. |
| 16 | PULSE2 | output | Programmable digital output pin for energy pulse signals, interrupt flags, or detection status outputs configurable via Pulse1Sel register (0x1DH). |
