Real Time Clock Procurement Notes

Verify the specific suffix B0 against official Epson documentation to confirm package type and tape/reel specifications. Confirm availability status as distribution channels may list restricted or obsolete stock. Ensure compatibility with existing serial 3-wire interfaces on the target PCB design before procurement.

Real Time Clock Selection Notes

Select this component when a low-pin-count RTC solution is required. The serial 3-wire interface reduces board space compared to parallel alternatives. Verify that the system logic levels align with the 1.6V to 5.5V operating range. Consider the industrial temperature rating if the application environment exceeds standard commercial limits.
