RX-8571LC:B3 PURE SN

Real Time Clock Overview

The RX-8571LC:B3 PURE SN is a Real Time Clock (RTC) manufactured by Epson Timing. It belongs to the RX-4571LC series and utilizes a Serial 3-Wire bus interface for data communication. The device operates within a supply voltage range of 1.6 V to 5.5 V and supports surface mount installation. It is designed for functionality in industrial temperature environments, specifically ranging from -40°C to +85°C. The component does not include a battery backup switching mechanism. Packaging is provided in bulk quantities.

Real Time Clock Feature Summary

Real Time Clock Procurement Notes

Verify the specific suffix B3 against official Epson documentation to confirm package dimensions and tape/reel specifications. Confirm availability status as distribution channels may vary. Ensure compatibility with existing 3-wire serial protocols before procurement.

Real Time Clock Selection Notes

Select this component when a compact RTC with low pin count is required. The 3-wire interface reduces PCB routing complexity compared to I2C or SPI alternatives. Verify that the 1.6V minimum voltage meets the system's standby power requirements.

Real Time Clock Part Context

This part is a variant within the RX-4571LC family. The LC designation typically indicates a specific leadless chip carrier or similar small outline package format suitable for automated surface mount assembly processes.

Real Time Clock Replacement Considerations

Direct replacements must support the 3-wire serial protocol and match the 1.6V-5.5V voltage window. Pinout compatibility should be verified against the official datasheet to ensure interchangeability without schematic changes.
