RTC-72423A0:ROHS

Real Time Clock Overview

The EPSON RTC-72423A0:ROHS is a surface-mount real-time clock (RTC) module belonging to the RTC-72423 series. It provides timekeeping and calendar functions via a parallel interface, supporting both 12-hour and 24-hour formats. The device operates within a supply voltage range of 4.5V to 5.5V and features low current consumption, typically between 5µA and 10µA depending on the voltage level. It includes automatic leap year compensation and supports an operating temperature range from -40°C to +85°C.

Real Time Clock Feature Summary

• Surface-mount package (24-SOP/SOIC)
• Parallel bus interface
• Automatic leap year setting
• Low current consumption (5µA ~ 10µA)

Real Time Clock Applications

• Industrial control systems requiring precise timekeeping
• Data logging equipment
• Telecommunications infrastructure

Real Time Clock Part Context

This component is part of the Epson RTC-72423 series, which serves as the surface-mount counterpart to the through-hole RTC-72421 series. The '0:ROHS' suffix indicates compliance with RoHS standards. While functionally similar to the RTC-72423B, specific electrical tolerances or pinout variations may exist between these sub-models.

Real Time Clock Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verification against the official Epson RTC-6242/7242 Part Number Guide is required for any potential replacements.
