RX-4803LC:UBB PURE SN

Real Time Clock Overview

The RX-4803LC:UBB PURE SN is a Real-Time Clock (RTC) module manufactured by Epson Timing. It operates on an I2C bus interface and provides timekeeping with a date format of YY-MM-DD-dd and time formats supporting both 12-hour and 24-hour modes. The device functions within a supply voltage range of 1.6 V to 5.5 V and supports an operating temperature range from -40°C to +85°C. It does not include a battery backup switching mechanism. The component is housed in a VSOJ-12 package and is designed for surface mount installation.

Real Time Clock Feature Summary

• I2C bus interface for digital communication
• Wide operating voltage range of 1.6 V to 5.5 V
• Industrial temperature range support (-40°C to +85°C)
• VSOJ-12 surface mount package

Real Time Clock Applications

• General purpose real-time clocking in embedded systems
• Data logging devices requiring precise time stamps
• Consumer electronics with low power requirements

Real Time Clock Procurement Notes

Verify the specific suffix 'UBB' against official Epson documentation to confirm pinout and electrical characteristics, as variations exist within the RX-4803LC family. Ensure compatibility with the target PCB footprint for the VSOJ-12 package. Confirm availability through authorized distributors, as stock levels may vary.

Real Time Clock Selection Notes

Select this component when an I2C interface is required instead of SPI. Compare accuracy specifications against other models like the RX-4803SA series if higher precision is needed. Verify that the VSOJ-12 package dimensions fit the design constraints. Check if battery backup switching is necessary for the application, as this model lacks that feature.

Real Time Clock Part Context

This part belongs to the Epson RX-4803LC series of real-time clocks. It shares the core RTC functionality with other variants in the series but differs in package type and interface configuration. The 'PURE SN' designation typically indicates lead-free and halogen-free compliance.

Real Time Clock Replacement Considerations

Direct replacements within the same series include RX-4803LC:UB0 or RX-4803LC:UB3, provided the package and interface requirements match. Cross-series replacement with the RX-4803SA requires adapting to an SPI interface and SOP-14 package.
