RV-8803-C7 Pinout — SON-8 Package

Notes

• I²C Interface: Pins 1 (SDA) and 8 (SCL) form the I²C bus interface, rated for 400 kHz operation.
• Clock Output: Pin 2 (CLKOUT) provides selectable frequencies: 32.768 kHz, 1024 Hz, or 1 Hz. Pin 4 (CLKOE) enables/disables this output.
• Power: Pin 3 (VDD) and Pin 5 (VSS) are power and ground respectively. Metal lid is connected to VSS (pin 5).
• Interrupt & Event: Pin 6 (INT) provides interrupt output; Pin 7 (EVI) is the event input with time-stamp capability.
• Low Power: Typical current consumption is 240 nA @ 3 V in timekeeping mode.
