WL700

WL · RF Transceiver ICs · SOP-8

WL700 from WL, in a SOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VSSRF power_in RF ground pin. Connect to the board ground plane.
2 ANT input RF signal input pin. Connects to the antenna matching network (typical: series C 2.2p with parallel L 27nH / C 4.7p and shunt L 33nH).
3 VDDRF power_in Power supply pin, 2.0-5.5 V (typical 3.3 V). Requires an external decoupling capacitor to ground; for 5 V applications insert a 47 Ω series resistor to protect the chip.
4 CTH passive Reference/threshold pin for the internal data slicer/comparator. Requires an external capacitor (typical 0.47 µF) to ground. Source impedance ~145 kΩ.
5 DO output Demodulated digital data output. In SHUTDOWN mode this pin is in a weak pull-down state.
6 SHUT input Shutdown control input. Tie to VDD for shutdown mode (0.1 µA typ.); tie to GND for normal operating (receive) mode. Startup time from SHUT-low to receiving is 3 ms.
7 CAGC passive AGC filter/hold capacitor pin. May be left unconnected (typical schematic shows optional cap C5 to ground; the datasheet explicitly notes pin 7 can be left floating).
8 REFOSC passive External reference crystal connection. Use 4.897 MHz for 315 MHz operation or 6.7458 MHz for 433.92 MHz operation. Input impedance ~290 kΩ, source current ~5.2 µA.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: WL datasheet (8 pp, sha256 b1cea904b90304a1, retrieved 2026-08-17, tier: lcsc)
  • Datasheet language: Chinese. Pin names, descriptions, and specs on this page were extracted and translated to English by ds2sf; the linked PDF is the manufacturer original.
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
