RX-8035LC:B PURE SN

Real Time Clock Overview

The RX-8035LC:B PURE SN is a Real Time Clock (RTC) IC manufactured by Epson Timing. It features an I2C bus interface and supports date formats of YY-MM-DD-dd and time formats of HH:MM:SS in both 12-hour and 24-hour modes. The device operates within a supply voltage range of 2.4 V to 5.5 V and includes battery backup switching capabilities. It is housed in a 12-VSOJ package and functions reliably across a temperature range of -40°C to +85°C. The maximum current consumption for timing is specified at 2.5 µA when powered at 3 V.

Real Time Clock Feature Summary

• I2C bus interface with alarm functionality

Real Time Clock Procurement Notes

Verify the specific suffix 'B' against official Epson documentation, as standard listings often reference variants like ':AA', ':AC0', or ':B3'. Confirm package type and voltage specifications directly with the manufacturer or authorized distributors to ensure compatibility with system design requirements.

Real Time Clock Selection Notes

Select this component for applications requiring low power consumption and I2C connectivity. Ensure the design accommodates the 12-VSOJ surface mount package. Verify that the operating environment stays within the specified -40°C to +85°C temperature range and that the supply voltage remains between 2.4 V and 5.5 V.

Real Time Clock Part Context

This part belongs to the RX-8035LC series of real-time clocks from Epson Timing. Related variants include RX-8035LC:AA, RX-8035LC:AC0, and RX-8035SA models, which share similar interfaces but may differ in packaging, calibration, or specific feature sets.

Real Time Clock Replacement Considerations

Direct substitutes are not explicitly confirmed in public data. Consider checking Epson's internal cross-reference lists or evaluating other I2C RTCs with compatible voltage and package constraints if exact replacement is required.
