CM315DL32768DZFT from CITIZEN, in a SMD3215-2P. 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 | One terminal of the 32.768 kHz tuning fork crystal, connected internally to one side of the crystal element and to one of the two pads, with CL options of 6/7/9/12.5 pF. |
| 2 | XTAL2 | passive | Other terminal of the 32.768 kHz tuning fork crystal, connected internally to the opposite side of the crystal element, with a motional resistance of 50k ohm max and drive level of 1 uW max. |
