PCF85363A - Tiny Real-Time Clock/Calendar

General Description

The PCF85363A is a CMOS1 Real-Time Clock (RTC) and calendar optimized for low power consumption and with automatic switching to battery on main power loss.

The RTC can also be configured as a stop-watch (elapsed time counter).

Key Features

  • UL Recognized Component (PCF85363ATL).
  • Provides year, month, day, weekday, hours, minutes, seconds and 100th seconds based on a 32.768 kHz quartz crystal.
  • Stop-watch mode for elapsed time counting. From 100th seconds to 999 999 hours.
  • Two independent alarms.
  • Battery back-up circuit.
  • WatchDog timer.
  • Three timestamp registers.
  • Two independent interrupt generators plus predefined interrupts at every second, minute, or hour.

tamp input, and I2C-bus Rev. 3.2 — 22 September 2021 Product data sheet 1 General description The PCF85363A is a CMOS1 Real-Time Clock (RTC) and calendar optimized for low power consumption and with automatic switching to battery on main power loss. The RTC can also be configured as a stop-watch (elapsed time counter). Three time log registers triggered from battery switch-over as well as input driven events. Featuring clock output and two independent interrupt signals, two alarms, I2C interface and quartz crystal calibration, 64 byte battery backed-up RAM.
