PT7C4563LEX

Real Time Clock Overview

The PT7C4563LEX is a Real-Time Clock (RTC) module manufactured by Diodes Incorporated. It features an I2C bus interface and utilizes Binary-Coded Decimal (BCD) formats for both date and time data. The device operates within a supply voltage range of 1.3 V to 5.5 V and supports a battery backup voltage of 3 V. It is housed in an 8-pin TSSOP package designed for surface mount technology. The component functions as a clock/calendar IC, providing timekeeping capabilities with alarm features.

Real Time Clock Feature Summary

• I2C and SMBus compatible bus interface
• BCD format for time (HH:MM:SS) and date (YY-MM-DD-dd)
• Wide operating voltage range from 1.3 V to 5.5 V
• Integrated alarm functionality

Real Time Clock Applications

• Consumer electronics requiring precise timekeeping
• Industrial control systems needing RTC integration
• Automotive infotainment and monitoring units

Real Time Clock Procurement Notes

Verify the specific suffix 'LEX' against the manufacturer's official datasheet to confirm package type and tape-and-reel specifications. Ensure compatibility with system voltage levels between 1.3 V and 5.5 V. Confirm that the I2C address matches the design requirements before procurement.

Real Time Clock Selection Notes

Select this component when an I2C-connected RTC with BCD output is required. Verify that the TSSOP-8 package fits the PCB layout constraints. Check if the -40°C to +85°C or extended temperature range meets the application environment needs. Compare power consumption specs if battery life is a critical factor.

Real Time Clock Part Context

This part belongs to the PT7C4563C series of real-time clock modules. It shares core functionalities with variants like PT7C4563CLEX and PT7C4563BQ1WEX, differing primarily in packaging and automotive qualification status. The LEX suffix typically denotes a specific tape-and-reel configuration for automated assembly.

Real Time Clock Replacement Considerations

Direct substitutes include other PT7C4563 series variants such as PT7C4563CLEX or PT7C4563BQ1WEX, provided the package and temperature ratings align. Cross-reference pinouts and I2C addresses to ensure functional equivalence without hardware redesign.
