SX25Y026000B71T from TKD, in a SMD2520-4P. 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 | Crystal terminal (pins 1 and 3 are the crystal connections); the 26.000MHz fundamental AT-cut crystal is specified for 7pF load capacitance. |
| 2 | GND | power_in | Ground connection (pins 2 and 4 are GND) on the ceramic package. |
| 3 | XTAL2 | passive | Crystal terminal (pins 1 and 3 are the crystal connections); drive level 100uW max. |
| 4 | GND | power_in | Ground connection (pins 2 and 4 are GND) on the ceramic package. |
