XL3232

XINLUDA · RS232 ICs · SOP-16

XL3232 from XINLUDA, in a SOP-16. 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 C1+ passive Positive lead of the C1 capacitor for the internal charge pump, which requires four external capacitors of 0.1 µF.
2 V+ power_out Positive charge pump output for storage capacitor only; the datasheet specifies V+ absolute maximum of 7 V.
3 C1- passive Negative lead of the C1 capacitor for the internal charge pump.
4 C2+ passive Positive lead of the C2 capacitor for the internal charge pump.
5 C2- passive Negative lead of the C2 capacitor for the internal charge pump.
6 V- power_out Negative charge pump output for storage capacitor only; the datasheet specifies V- absolute maximum of -7 V.
7 DOUT2 output RS232 line driver output to the remote RS232 system; outputs are protected against shorts to ground.
8 RIN2 input RS232 line receiver input from the remote RS232 system, with an internal standard RS232 load; an open input gives a high ROUT output.
9 ROUT2 output Logic data output to the UART from the RS232 receiver.
10 DIN2 input Logic data input from the UART to the RS232 driver; all DIN inputs must be valid low or high logic levels.
11 DIN1 input Logic data input from the UART to the RS232 driver; all DIN inputs must be valid low or high logic levels.
12 ROUT1 output Logic data output to the UART from the RS232 receiver.
13 RIN1 input RS232 line receiver input from the remote RS232 system, with an internal standard RS232 load.
14 DOUT1 output RS232 line driver output to the remote RS232 system; outputs are protected against shorts to ground.
15 GND power_in Ground reference for the device.
16 VCC power_in Supply voltage, connect to external 3-V to 5.5-V power supply.
