RX-8803LC:UB0 PURE SN

Real Time Clock Overview

The RX-8803LC:UB0 PURE SN is a Real Time Clock (RTC) manufactured by Epson Timing. It features an I2C bus interface for data communication and supports date formats of YY-MM-DD-dd and time formats of HH:MM:SS in 24-hour mode. The device operates within a supply voltage range of 1.6 V to 5.5 V and functions reliably across a temperature range of -40°C to +85°C. It utilizes a VSOJ-12 package suitable for surface mount technology (SMD/SMT). The component does not include a backup switching mechanism.

Real Time Clock Feature Summary

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

Real Time Clock Applications

• Industrial control systems requiring precise timekeeping
• Automotive electronics operating in harsh environments
• Consumer devices needing low-power real-time clock functionality

Real Time Clock Procurement Notes

Verify the specific suffix 'PURE SN' against official Epson documentation to confirm exact packaging and compliance status. Confirm that the VSOJ-12 package dimensions match the target PCB footprint. Ensure the I2C address configuration aligns with system design requirements before procurement.

Real Time Clock Selection Notes

Select this component when an I2C-connected RTC is required with a wide voltage input capability. The -40°C to +85°C rating makes it suitable for automotive or industrial applications where standard commercial grade parts may fail. Verify that the system power rails remain above 1.6 V during all operational states.
