Tiny Real-Time Clock/Calendar with 64 B RAM, Alarm Function, Battery Switch-Over Time Stamp Input and I²C-Bus

PCF85363A Active

The PCF85363A is a CMOS 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.

Product Details

Features

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 999999 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
  • 64 byte battery backed-up RAM
  • Frequency adjustment via programmable offset register
  • Clock operating voltage: 0.9 V to 5.5 V
  • Low current; typical 0.28 μA at VDD = 3.0 V and Tamb = 25 °C
  • 400 kHz two-line I²C-bus interface (at VDD = 1.8 V to 5.5 V)
  • Programmable clock output for peripheral devices (32.768 kHz, 16.384 kHz, 8.192 kHz, 4.096 kHz, 2.048 kHz, 1.024 kHz, and 1 Hz)
  • Configurable oscillator circuit for a wide variety of quartzes: CL = 6 pF, CL = 7 pF, and CL = 12.5 pF
