# VX1527L

**VIBRATION** · RF Transceiver ICs · SOP-8

VX1527L from VIBRATION, 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 | NC | unconnected | Pin 1 is not connected and should be left floating (悬空). |
| 2 | VDD | power_in | Supply input operating from 2.2 V to 5.5 V; the absolute maximum supply is -0.3 V to 5.5 V. |
| 3 | GND | power_in | Ground connection for the device. |
| 4 | TXD | output | Encoded data output of the learning-code encoder. |
| 5 | K0 | input | Key input with built-in pull-down resistor; it must only be pulled high after VDD has powered up and stabilized. |
| 6 | K1 | input | Key input with built-in pull-down resistor for key combination scanning. |
| 7 | K2 | input | Key input with built-in pull-down resistor for key combination scanning. |
| 8 | K3 | input | Key input with built-in pull-down resistor for key combination scanning. |
