RX-8571LCB0 PURE SN

Real Time Clock Overview

The RX-8571LCB0 PURE SN is a Real Time Clock (RTC) IC manufactured by Epson Timing. It features an I2C reset bus interface and supports YY-MM-DD-dd date and HH:MM:SS (24 hr) time formats with reset functionality. The device includes 16 bytes of RAM storage capacity and operates without battery backup switching. It functions within a supply voltage range of 1.6 V to 5.5 V and is rated for temperatures between -40°C and +85°C. The component is housed in a VSOJ-12 package, suitable for surface mount applications.

Real Time Clock Feature Summary

• I2C Reset bus interface with 16-byte RAM storage
• Operates on 1.6 V to 5.5 V supply voltage
• VSOJ-12 surface mount package
• Temperature range from -40°C to +85°C

Real Time Clock Applications

• General purpose real-time clocking in embedded systems
• Data logging devices requiring calendar and time tracking
• Industrial equipment operating in extended temperature environments

Real Time Clock Procurement Notes

Verify the specific suffix 'PURE SN' against official Epson documentation to confirm material composition and compliance status. Confirm availability through authorized distributors as stock levels fluctuate. Ensure the VSOJ-12 package footprint matches the target PCB design before ordering.

Real Time Clock Selection Notes

Select this model when an I2C Reset interface is required rather than standard I2C. Verify that the 1.6 V minimum operating voltage aligns with the system's power rails. The VSOJ-12 package requires appropriate soldering profiles for fine-pitch surface mount assembly.

Real Time Clock Part Context

This part belongs to the Epson RX-8571LC series of real-time clocks. It shares core specifications with other variants in the family but differs in package type and interface configuration. The LC designation typically indicates specific pinout or feature sets distinct from SA or NB series counterparts.

Real Time Clock Replacement Considerations

Direct replacements include other RX-8571LC variants if package compatibility allows. Cross-reference with RX-8571SA:B3 PURE SN only if interface differences (I2C vs I2C Reset) are accommodated by the system design.
