Real Time Clock Procurement Notes

Verify the specific suffix 'B06' against official Epson documentation to confirm accuracy, as datasheets may list variations such as 'XS A0' or 'XB B0'. Confirm package availability and lead times directly with authorized distributors, as stock levels fluctuate. Ensure compliance with RoHS requirements specified in the manufacturer's certificate of compliance before procurement.

Real Time Clock Selection Notes

Select this model when high stability is required, noting that the 'XS' designation typically indicates a frequency tolerance of ±3 ppm. Compare against the 'XB' variant if a ±5 ppm tolerance is acceptable for cost reduction. Verify that the I2C interface compatibility matches the host microcontroller. Ensure the operating environment stays within the -40°C to +105°C thermal limits defined for this series.
