Real Time Clock Procurement Notes

Verify the exact suffix against official Epson documentation to confirm RoHS compliance status and specific binning codes. Ensure the ordering part number matches the required package type and tape/reel specifications for your manufacturing line. Cross-reference the datasheet revision history to confirm pinout compatibility with existing designs before finalizing procurement orders.

Real Time Clock Selection Notes

Select this component when a dedicated hardware RTC is preferred over MCU internal timers for long-term accuracy. Consider the I2C interface speed limitations and pull-up resistor requirements for your bus topology. Evaluate the backup power input pin availability if continuous timekeeping during main power loss is critical for your application architecture.

Real Time Clock Part Context

This part belongs to the RX-8564LC series family of real-time clocks manufactured by Epson Toyocom. These components are widely used in consumer electronics and industrial automation where space-constrained, high-accuracy timekeeping is essential. The NB variant typically denotes specific packaging or testing configurations within the broader product line.

Real Time Clock Replacement Considerations

Direct substitutes may include other I2C-based RTCs from manufacturers like NXP or STMicroelectronics. Verify register-level compatibility and pinout alignment before swapping. Alternative Epson parts within the same series should be checked for minor electrical parameter differences.
