RTC-72423B3: ROHS

Real Time Clock Overview

The RTC-72423B3:ROHS is a CMOS Real Time Clock (RTC) integrated circuit manufactured by Seiko Epson. It provides clock and calendar functions in a 24-pin SOIC package. The device operates on a supply voltage range of 4.5V to 5.5V. It supports time formats including HH:MM:SS in both 12-hour and 24-hour modes. The component is RoHS compliant and lead-free, designed for surface mount applications.

Real Time Clock Feature Summary

• Provides accurate clock and calendar counting capabilities
• Supports standard parallel interface communication
• Operates within a specified voltage range of 4.5V to 5.5V
• Complies with RoHS environmental standards

Real Time Clock Applications

• General purpose real-time clocking in electronic systems
• Data logging devices requiring time stamping
• Embedded systems needing calendar functionality

Real Time Clock Procurement Notes

Verify the specific ordering suffix matches the required package and compliance status. Confirm that the 24-SOIC footprint aligns with the target PCB design. Ensure the voltage supply meets the 4.5V to 5.5V operational requirements. Check for any specific handling instructions related to the CMOS technology used in this component.

Real Time Clock Selection Notes

Select this component when a dedicated parallel interface RTC is required for 12/24 hour timekeeping. Consider the 24-pin SOIC package constraints for board layout. Evaluate the need for volatile memory characteristics inherent to this RTC type. Ensure the system power supply remains stable within the specified operating range.

Real Time Clock Part Context

This part belongs to the Epson RTC-72423 series of real-time clocks. It is distinct from other variants like the RTC-72423A which may have different packaging or reel specifications. The B3 suffix typically denotes specific manufacturing or compliance attributes defined by the manufacturer.

Real Time Clock Replacement Considerations

Direct substitutes include other parts within the Epson RTC-72423 family, such as the RTC-72423A:3:ROHS, provided the pinout and interface compatibility are verified. Cross-reference package dimensions and electrical specifications before substitution.
