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. |
