STPM10BTR from STMicroelectronics, in a TSSOP-20. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | WDG | output | Watchdog output that gives a 16 ms positive pulse every 1.6 s while the host keeps latching data, and goes active high if latching requests are not made within 1.6 s. |
| 2 | ZCR | output | Zero-crossing signal output (see Section 7.4 for the ZCR signal). |
| 3 | SCS | input | SPI interface enable pin: SPI operation is enabled when SCS is low, and SCS is also the idle-state control for the SPI pins. |
| 4 | VDDD | power_out | 1.8 V output of the internal low-drop regulator that supplies the digital core; a 100 nF low-ESR capacitor to VSS should be placed close to the pin. |
| 5 | VSS | power_in | Ground and reference point for all internal signals. |
| 6 | VCC | power_in | Main supply voltage input; the DC input is rated -0.3 to 6 V and the device is held in reset when VCC is below 2.5 V. |
| 7 | VO | power_out | Output of the internal low-drop regulator. |
| 8 | VDDA | power_out | 3 V output of the internal low-drop regulator that supplies the analog part; a 100 nF low-ESR capacitor to VSS should be placed close to the pin. |
| 9 | IIP1 | input | Positive input of the primary current channel; analog input voltage is limited to -0.7 to 0.7 V. |
| 10 | IIN1 | input | Negative input of the primary current channel; analog input voltage is limited to -0.7 to 0.7 V. |
| 11 | IIP2 | input | Positive input of the secondary current channel; analog input voltage is limited to -0.7 to 0.7 V. |
| 12 | IIN2 | input | Negative input of the secondary current channel; analog input voltage is limited to -0.7 to 0.7 V. |
| 13 | VIP | input | Positive input of the voltage channel; analog input voltage is limited to -0.7 to 0.7 V. |
| 14 | VIN | power_in | Negative input of the voltage channel; analog input voltage is limited to -0.7 to 0.7 V. |
| 15 | SYN | bidirectional | SPI interface pin used for latching and read/write mode selection; the pin table lists it as I/O while Section 7.19 describes it as an input. |
| 16 | CLKIN | input | Crystal oscillator input, used when the crystal oscillator is selected (RC bit = 0). |
| 17 | CKOUT | output | Crystal oscillator output, used when the crystal oscillator is selected. |
| 18 | SCL | bidirectional | SPI interface clock pin; the pin table lists it as I/O while Section 7.19 describes it as an input clock. |
| 19 | SDA | bidirectional | SPI interface data pin: input in write mode and output in read mode, with an internal weak pull-up of about 15 µA. |
| 20 | LED | output | Active energy pulsed output whose pulse rate is proportional to energy and is used for calibration. |
