Starwave(思大) · IC · HC-49S-SMD
SWXJEBCVH0-8.704000 from Starwave(思大), in a HC-49S-SMD. 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 | XTAL1 | passive | First crystal terminal (left pad in the drawing); 8.704 MHz crystal with 18 pF load capacitance unless specified, 7 pF max shunt capacitance, drive level 1~500 µW (100 µW typical). |
| 2 | XTAL2 | passive | Second crystal terminal (right pad in the drawing); non-polarized, pairs with the first terminal across the quartz unit, operating range -40 to +85 ºC. |
