Real Time Clock Procurement Notes

Verify current availability status as inventory levels may fluctuate. Confirm package type matches design requirements, as this part is listed with Bulk packaging. Ensure compatibility with the 3-wire serial interface protocol during integration planning.

Real Time Clock Selection Notes

Select this component when a low-voltage RTC with a simple serial interface is required. The absence of a battery backup switch necessitates external circuitry if seamless power transition is needed. Verify that the 12-pin VSOJ form factor fits the target PCB layout constraints.

Real Time Clock Part Context

This part belongs to the RX-4571LC series of real-time clocks. It shares functional similarities with other Epson RTCs but is distinguished by its specific pin count and interface type. The 'PURE SN' suffix indicates lead-free composition without halogenated flame retardants.

Real Time Clock Replacement Considerations

Direct substitutes are not explicitly confirmed in public documentation. Consider checking the RX-4571SA series for similar functionality in different packages, though interface and pinout differences must be evaluated carefully.
