  • PCA85073A: Automotive Tiny Real-Time Clock/Calendar with Alarm Function and I²C-Bus
  • PCA85063A: Automotive Tiny Real-Time Clock/Calendar with Alarm Function and I²C-bus

Features

Key Features

  • To visualize the interrupt an LED (D1) is mounted. To minimize the power consumption, it can be switched off by removing the jumper J2
  • No need to solder the tiny package to a breadboard 100 mil connector for straight forward connections
  • The OM13515 allows easily demonstrating the operation of the PCx85063A with I²C-bus interface

Straight Forward Interfacing

  • Connect supply voltage (e.g. 3.3 V): VSS to pin 1, VDD to pin 2
  • Connect I²C-bus (pull-up resistor needed): SCL to pin 4, SDA to pin 3
  • Connect interrupt and/or CLKOUT if required Communicate with the RTC
