LR670L

蜂鸟无线 · RF Transceiver ICs · SOT-23-6

LR670L from 蜂鸟无线, in a SOT-23-6. 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 RO passive Crystal (reference oscillator) pin; the datasheet lists the function as crystal (晶振), with a 13.52127 MHz crystal frequency for 433.92 MHz.
2 GND power_in Power ground.
3 SHUT input Mode select input: 0 = operating mode, 1 = shutdown mode (standby current 0.3 µA typ. with VSHUT=VDD).
4 DO output Data output, CMOS level.
5 VDD power_in Positive supply, 3.5 V to 5.5 V (typical 5 V).
6 ANT input Antenna input (RF), specified with a 50 Ω source resistance.

  • Symbol: LR670L
  • Footprint: Package_TO_SOT_SMD:SOT-23-6
  • 3D model: SOT-23-6 (KiCad packages3D, STEP)
  • 3D model files: lr670l-etched.step / lr670l-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); lr670l.step / lr670l.glb are the bare package body.
