Real Time Clock Procurement Notes

Verify the specific suffix 'XB3' against official Epson documentation to confirm pinout and functional specifications, as suffixes often denote packaging or specific variant details. Ensure compatibility with the target system's I2C voltage levels given the 1.6V-5.5V operating range. Check for RoHS3 compliance status if required by regional regulations.

Real Time Clock Selection Notes

Select this component when a low-power, high-accuracy RTC is needed for space-constrained designs. The 10-SMD package suits automated surface-mount assembly. Verify that the I2C address configuration meets system requirements. Consider the -40°C to +105°C operating range for industrial or automotive environments where standard commercial grade parts may fail.

Real Time Clock Part Context

The RA8804CE belongs to Epson's RX8804 series of real-time clocks. This series is designed for applications requiring reliable timekeeping with minimal power draw. The RA8804CE XB3 is a specific variant within this family, distinguished by its packaging and potential internal configuration options defined by the manufacturer's part numbering system.
