RX-8803SAUC0 PURE SN

Real Time Clock Overview

The RX-8803SAUC0 PURE SN is a Real Time Clock (RTC) module manufactured by Epson Timing. It features an I2C bus interface for data communication and supports date formats of YY-MM-DD-dd and time formats of HH:MM:SS:hh in both 12-hour and 24-hour modes. The device operates within a supply voltage range of 1.6 V to 5.5 V and functions reliably across a temperature range of -40°C to +85°C. It utilizes a VSOJ-12 package and does not include a battery backup switching mechanism.

Real Time Clock Feature Summary

• I2C bus interface for serial communication
• Operates on 1.6 V to 5.5 V power supply
• VSOJ-12 surface mount package
• Wide operating temperature range from -40°C to +85°C

Real Time Clock Applications

• Industrial control systems requiring precise timekeeping
• Consumer electronics with real-time clock needs
• Automotive embedded applications within specified temperature limits

Real Time Clock Procurement Notes

Verify the specific suffix 'UC' against official Epson documentation to confirm package type and availability status, as distribution listings may vary. Confirm RoHS compliance requirements if applicable to your manufacturing standards. Check for any end-of-life notifications or discontinuation notices directly from the manufacturer before finalizing procurement plans.

Real Time Clock Selection Notes

Select this component when an I2C interface is required for RTC functionality in space-constrained designs due to the VSOJ-12 package. Ensure the system voltage remains within the 1.6 V to 5.5 V range. Consider the +/-5.0 PPM accuracy typical for this series if high precision is needed, and verify that the -40°C to +85°C operating range meets environmental conditions.

Real Time Clock Part Context

This part belongs to the RX-8803LC/SA series of real-time clocks from Epson Timing. These components are designed for general-purpose timekeeping in various electronic devices. The SA variant typically denotes specific interface or performance characteristics compared to other series members like the LC version.

Real Time Clock Replacement Considerations

Direct substitutes should be sought within the Epson RX-8803 family, such as the RX-8803LCUA0, ensuring pin compatibility and interface matching. Verify that alternative parts meet the same voltage, temperature, and accuracy specifications.
