LR690L

Feng Niao RF · RF Transceiver ICs · SOT-23-6

LR690L from Feng Niao RF, in a SOT-23-6. 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 XTAL passive Crystal oscillator connection; external crystal frequency selected per FOSC = FRF/32 (÷1/32), e.g. 9.81563 MHz for 315 MHz or 13.52127 MHz for 433.92 MHz RF.
2 GND power_in Power supply negative (ground); 0 V reference for all internal circuits.
3 SHUT input Shutdown control input, active-low; low level = normal operation, open or high level = sleep mode (ISTBY = 0.3 μA typ).
4 DATA output Demodulated ASK/OOK data output; logic level follows received signal envelope, data rate up to 10 kbps.
5 VDD power_in Power supply positive; operating range 2.0 V to 5.5 V (typ 3.3 V); working current 2.8 mA at 315 MHz, 2.9 mA at 433.92 MHz (3.3 V), sleep current 0.3 μA.
6 ANT input RF signal input; connect to antenna via matching network; sensitivity −110 dBm (ASK/OOK), spurious reverse isolation −20 dBm, ANT pin impedance RSC = 50 Ω.
