Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | DVDD | power_in | Digital power supply input, 3.0V to 5.5V. |
| 2 | VDD1P8 | power_out | 1.8V regulated digital output with external 0.1µF and 1µF capacitor connection required. |
| 3 | Test\ | input | Test mode pin with internal strong pull-up, recommend external pull-up to high level. |
| 4 | AVCC | power_in | Analog power supply input, 3.0V to 5.5V. |
| 5 | V3P | input | Voltage channel positive input with peak range ±870mV. |
| 6 | V3N | input | Voltage channel negative input reference. |
| 7 | V2P | input | Current channel 2 single-ended input with peak range ±900mV. |
| 8 | V1P | input | Current channel 1 positive input with peak range ±900mV differential. |
| 9 | V1N | input | Current channel 1 negative input reference. |
| 10 | VREF | power_in | ADC reference voltage output, typical 1.2V with external 0.1µF and 1µF capacitor connection required. |
| 11 | AGND | power_in | Analog ground. |
| 12 | SPI/UART | input | Communication protocol selection pin, default pull-up for SPI mode, low for UART mode. |
| 13 | QF/SF | output | Reactive power pulse output (default) or apparent power pulse output selectable by register configuration. |
| 14 | PF | output | Active power pulse output. |
| 15 | IRQ\ | output | Interrupt signal output, active low by default (configurable to active high via IRQCFG register). |
| 16 | SPICS/B1 | input | SPI chip select active low in SPI mode, or baud rate select bit in UART mode. |
| 17 | S0 | input | UART frame header selection pin (UART mode only), high for 0x6A header or low for 0x69 header. |
| 18 | RST\ | input | Chip reset pin active low, requires greater than 30ms low pulse to reset. |
| 19 | SPIDI/RX | input | SPI serial data input in SPI mode or UART receive data input in UART mode with internal pull-up. |
| 20 | SPIDO/TX | tri_state | SPI serial data output in high-impedance state in SPI mode or UART transmit data output in UART mode. |
| 21 | SPICLK/B0 | input | SPI clock input in SPI mode (data latched on falling edge), or baud rate select bit in UART mode. |
| 22 | OSCI | input | 6MHz crystal oscillator input. |
| 23 | OSCO | output | 6MHz crystal oscillator output. |
| 24 | DGND | power_in | Digital ground. |
