AiP1620 from Wuxi I core Elec, in a SOP-20-300mil. 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 | VDD | power_in | Logic power supply voltage; recommended operating range 3-5.5V. |
| 2 | SEG1 | output | Segment 1 output, open-drain configuration capable of sourcing 50mA at VDD-2V or 40mA at VDD-3V. |
| 3 | SEG2 | output | Segment 2 output, open-drain configuration capable of sourcing 50mA at VDD-2V or 40mA at VDD-3V. |
| 4 | SEG3 | output | Segment 3 output, open-drain configuration capable of sourcing 50mA at VDD-2V or 40mA at VDD-3V. |
| 5 | SEG4 | output | Segment 4 output, open-drain configuration capable of sourcing 50mA at VDD-2V or 40mA at VDD-3V. |
| 6 | SEG5 | output | Segment 5 output, open-drain configuration capable of sourcing 50mA at VDD-2V or 40mA at VDD-3V. |
| 7 | SEG6 | output | Segment 6 output, open-drain configuration capable of sourcing 50mA at VDD-2V or 40mA at VDD-3V. |
| 8 | SEG7 | output | Segment 7 output, open-drain configuration capable of sourcing 50mA at VDD-2V or 40mA at VDD-3V. |
| 9 | SEG8 | output | Segment 8 output, open-drain configuration capable of sourcing 50mA at VDD-2V or 40mA at VDD-3V. |
| 10 | SEG13/GRID6 | output | Segment/Grid multiplex output, functions as segment or grid depending on display mode configuration (4-bit×10-segment through 6-bit×8-segment modes). |
| 11 | SEG14/GRID5 | output | Segment/Grid multiplex output, functions as segment or grid depending on display mode configuration (4-bit×10-segment through 6-bit×8-segment modes). |
| 12 | GND | power_in | Logic ground, system ground reference connection. |
| 13 | GRID4 | output | Grid 4 output, open-drain configuration capable of sinking 80-140mA at 0.3V. |
| 14 | GRID3 | output | Grid 3 output, open-drain configuration capable of sinking 80-140mA at 0.3V. |
| 15 | GND | power_in | Logic ground, system ground reference connection. |
| 16 | GRID2 | output | Grid 2 output, open-drain configuration capable of sinking 80-140mA at 0.3V. |
| 17 | GRID1 | output | Grid 1 output, open-drain configuration capable of sinking 80-140mA at 0.3V. |
| 18 | DIO | bidirectional | Serial data input/output with N-channel open-drain and internal 20kΩ pull-up resistor; reads data on clock rising edge, outputs data on falling edge. |
| 19 | CLK | input | Clock input for serial interface; reads serial data on rising edge and outputs data on falling edge; maximum frequency 1MHz at 50% duty cycle. |
| 20 | STB | input | Strobe/chip select input; initializes serial interface on rising or falling edge; first byte after STB low becomes command byte; CLK ignored when STB high. |

Package_SO:SOP-20_7.5x12.8mm_P1.27mm - 3D model: SOP-20-300mil, generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 2.65 mm nominal SOIC height). Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions are nominal, not the manufacturer's CAD (STEP)
