71 / 92 page ![]() NXP Semiconductors PCF85263A Tiny Real-Time Clock/calendar with alarm function, battery switch-over, time stamp input, and I2C-bus 15 Application information PCF85263A MASTER TRANSMITTER/ RECEIVER OSCI OSCO VSS SDA R aaa-010565 R SCL SDA (I2C-bus) SCL SDA SCL INTA VBAT VDD VDD 100 nF R: pull-up resistor R = tr Cb CLK VDD TS 100 nF Figure 44. Application diagram for PCF85263A The data sheet values were obtained using a crystal with an ESR of 60 kΩ. If a crystal with an ESR of 70 kΩ is used then the power consumption would increase by a few nA and the start-up time will increase slightly. 16 Test information 16.1 Quality information UL Component Recognition This (component or material) is Recognized by UL. Representative samples of this component have been evaluated by UL and meet applicable UL requirements.
