PCF8566P,112

Display Drivers Overview

The PCF8566P,112 is a CMOS Real-Time Clock (RTC) and calendar designed for low-power applications. It provides year, month, day, week, hour, minute, and second information based on a 32.768 kHz quartz crystal. The device features a 400 kHz I²C-bus interface, programmable clock output, alarm functions, and a timer. It includes an internal power-on reset and a voltage-low detector. Operating voltage ranges from 1.0 V to 5.5 V, with a typical standby current of 0.25 µA at 3.0 V.

Display Drivers Feature Summary

• Integrated real-time clock and calendar functionality providing comprehensive timekeeping data.
• Low standby current consumption suitable for battery-powered portable instruments.
• Programmable clock output and interrupt capabilities for peripheral synchronization.
• Built-in voltage-low detector and power-on reset for system reliability.

Display Drivers Applications

• Mobile phones
• Portable instruments
• Electronic metering
• Battery-operated products

Display Drivers Procurement Notes

Verify the specific suffix '112' corresponds to the DIP-8 package variant when sourcing. Confirm RoHS compliance status as some legacy listings may indicate discontinued manufacturing status. Ensure the I²C address configuration matches the target system requirements before integration.

Display Drivers Selection Notes

Select this component for designs requiring precise timekeeping with minimal power drain. The wide operating voltage range supports various logic levels. Consider the DIP-8 package constraints for PCB layout if through-hole mounting is required for the specific revision.

Display Drivers Part Context

This part belongs to NXP's PCF85xx series of real-time clocks. It serves as a standard solution for adding timekeeping capabilities to microcontroller-based systems without requiring external oscillators or complex timing circuits.

Display Drivers Replacement Considerations

PCF8563 variants are functionally similar RTCs within the same family. Verify pin compatibility and register mapping differences before substitution.
