PCF8563T-HXY

HXY MOSFET · Real-time Clocks (RTC) · SOP-8

PCF8563T-HXY from HXY MOSFET, in a SOP-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. Connect the 32.768 kHz quartz crystal between OSCI and OSCO. Internal load capacitance is provided (CINT typ 25 pF).
2 OSCO output Oscillator output. Second terminal of the 32.768 kHz crystal network.
3 /INT output Interrupt output, open-drain, active low. Asserted by the alarm/timer sources; requires an external pull-up to VDD.
4 VSS power_in Ground / negative supply reference (0 V).
5 SDA bidirectional I2C serial data I/O, open-drain. Requires external pull-up to VDD. Bus supports up to 400 kbit/s (fast-mode). Slave addresses: 0A3H (read) / 0A2H (write).
6 SCL input I2C serial clock input. Requires external pull-up to VDD. fSCL up to 400 kHz.
7 CLKOUT output Programmable clock output, open-drain. Selectable frequency of 32.768 kHz, 1024 Hz, 32 Hz or 1 Hz; requires an external pull-up to VDD.
8 VDD power_in Positive supply voltage, 2.5 V to 5.5 V. Absolute maximum +6.5 V. Typical IDD ~0.25 uA at VDD=3.0 V, TA=25 degC with CLKOUT disabled.
