RX8111CE B0

Real Time Clock Overview

The Epson RX8111CE B0 is a real-time clock (RTC) IC featuring an I2C bus interface. It supports YY-MM-DD-dd date and HH:MM:SS (24-hour) time formats with a backup switching mechanism for continuous operation. The device operates within a supply voltage range of 1.6 V to 5.5 V and functions across a temperature range of -40°C to +85°C. Designed for surface mount installation, it is available in reel or cut tape packaging with a factory quantity of 1,000 units.

Real Time Clock Feature Summary

• I2C bus interface for digital communication
• Automatic backup switching capability
• Wide operating voltage range from 1.6 V to 5.5 V
• Surface mount package options including Reel and Cut Tape

Real Time Clock Applications

• Embedded systems requiring precise timekeeping

• Industrial equipment operating in wide temperature environments

Real Time Clock Procurement Notes

Verify the specific suffix 'B0' against official Epson documentation to confirm exact manufacturing revisions and compliance status. Confirm that the required packaging format (Reel or Cut Tape) matches the intended assembly process. Ensure the I2C address configuration aligns with the system design before finalizing orders.

Real Time Clock Selection Notes

Select this component when an I2C-compatible RTC with automatic power source switching is required. The 1.6 V to 5.5 V input range allows compatibility with various logic levels. Verify that the 10-SMD footprint dimensions fit the PCB layout constraints. Check if the standard frequency adjustment capabilities meet the system's accuracy requirements.

Real Time Clock Part Context

This part belongs to the Epson RX8111CE series of real-time clocks. The 'B0' suffix denotes a specific version within this family. Related variants include the RX8111CE AB, which shares similar core functionalities but may differ in packaging or minor specifications. All parts utilize the same underlying RTC architecture.

Real Time Clock Replacement Considerations

Direct substitutes within the RX8111CE family should be verified via datasheets. Cross-model replacements require checking pinout compatibility and I2C register mapping. No alternative part numbers are confirmed as direct equivalents without further technical validation.
