XN297LBW from Vollgo, in a SOP-8. 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 | CSN | input | SPI chip select (active low); the chip executes one SPI command per CSN falling edge from high to low. |
| 2 | SCK | input | SPI serial clock input, with a maximum SPI rate of 4 Mbps in normal operation and 1 Mbps in sleep and standby-I modes. |
| 3 | DATA | bidirectional | SPI slave data input/output, used as the serial data line for the SPI interface in the SOP8 package. |
| 4 | VDD | power_in | Power supply input, +2.3 V to +3.3 V DC (absolute maximum VDD is -0.3 V to 3.6 V); the chip operates normally only when VDD is above 2.2 V. |
| 5 | XC1 | input | Crystal oscillator input, connected to the external crystal (reference schematic uses a 16 MHz crystal). |
| 6 | XC2 | output | Crystal oscillator output; the reference schematic places a 510 ohm series resistor on this pin to ensure all crystal oscillator types start correctly. |
| 7 | VSS | power_in | Ground (GND) reference, 0 V. |
| 8 | ANT | passive | Antenna interface for the 2.4 GHz RF input/output. |
