PCF8563MM from HGSEMI, 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 | Oscillator input for connection to 32.768kHz crystal; accepts input voltage from -0.5V to VDD+0.5V. |
| 2 | OSCO | output | Oscillator output from internal 32.768kHz oscillator with internal parallel load capacitance of 15-35pF (typical 25pF); output voltage range -0.5V to +6.5V. |
| 3 | INT | tri_state | Open-drain interrupt output; output voltage range -0.5V to +6.5V and maximum sink current -1mA at VOL=0.4V with VDD=5.0V. |
| 4 | VSS | power_in | Ground; 0V reference voltage. |
| 5 | SDA | bidirectional | Open-drain I2C serial data line; accepts input voltage from VSS to 0.3VDD (low level) or 0.7VDD to VDD (high level) and maximum sink current -3mA at VOL=0.4V with VDD=5.0V. |
| 6 | SCL | input | I2C serial clock input; accepts input voltage from VSS to 0.3VDD (low level) or 0.7VDD to VDD (high level) with maximum I2C bus frequency of 400kHz. |
| 7 | CLKOUT | tri_state | Open-drain programmable clock output (selectable 32.768kHz, 1024Hz, 32Hz, or 1Hz); output voltage range -0.5V to +6.5V and maximum sink current -1mA at VOL=0.4V with VDD=5.0V. |
| 8 | VDD | power_in | Positive power supply; operating voltage range 1.2V to 5.5V for I2C bus inactive, or 1.8V to 5.5V for I2C bus active at f=400kHz. |
