WS490H

wisesun · RF Transceiver ICs · SOP-8

WS490H from wisesun, 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 GND power_in Ground pin for the receiver (table 1: 接地管脚).
2 ANT input RF signal input pin for the 315/433 MHz ASK/OOK antenna, fed through the external matching network shown in the typical circuits.
3 VDD power_in Supply pin, rated DC 2.0 V to 5.5 V in operating conditions, with an absolute maximum of -0.3 V to 5.5 V.
4 NC unconnected No internal connection; leave floating (悬空).
5 DO output Demodulated digital data output; it is driven low when the chip is in shutdown (SHUT high) and carries the demodulated signal in normal operation.
6 SHUT input Operating-mode select: tie to VDD for shutdown mode (about 0.1 µA, DO low) and to GND for normal receive mode.
7 NC unconnected No internal connection; leave floating (悬空).
8 RO input External crystal connection for the internal Colpitts reference oscillator, with crystal frequency set by FOSC = FRF/(32+1.1/12), e.g. 13.52127 MHz for 433.92 MHz.
