PCF8563-TD from TDSEMIC, in a MSOP-8. 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 | OSCI | input | Crystal oscillator input; connect one leg of a 32.768 kHz quartz crystal. |
| 2 | OSCO | output | Crystal oscillator output; connect other leg of the 32.768 kHz quartz crystal. |
| 3 | /INT | output | Active-low open-drain interrupt output; asserted when an enabled alarm or timer interrupt condition occurs; requires external pull-up. |
| 4 | VSS | power_in | Ground reference (0 V). |
| 5 | SDA | bidirectional | I²C serial data I/O (bidirectional, open-drain); supports up to 400 kbits/s; requires external pull-up. |
| 6 | SCL | input | I²C serial clock input; maximum bus frequency 400 kHz. |
| 7 | CLKOUT | output | Programmable open-drain clock output; selectable frequency of 32.768 kHz, 1024 Hz, 32 Hz, or 1 Hz; requires external pull-up. |
| 8 | VDD | power_in | Positive supply voltage; operating range 2.5 V to 5.5 V; typical quiescent current 0.25 µA at VDD = 3.0 V, TA = 25 °C with CLKOUT disabled. |
