RX-8025NBAC0 PURE SN

Real Time Clock Overview

The RX-8025NBAC0 PURE SN is a Real Time Clock (RTC) integrated circuit manufactured by Epson Timing. It operates on an I2C bus interface and provides clock/calendar functions with a date format of YY-MM-DD-dd and time format of HH:MM:SS. The device supports a supply voltage range of 1.7V to 5.5V and consumes current between 1.2µA and 1.8µA at 3V to 5V. It features an alarm function and is housed in a 14-SOIC package with a width of 5.00mm. The component is designed for operation within a temperature range of -40°C to +85°C.

Real Time Clock Feature Summary

• I2C Bus Interface for simple wiring and communication
• Wide Supply Voltage Range from 1.7V to 5.5V
• Low Power Consumption of 1.2µA to 1.8µA @ 3V~5V
• Alarm Functionality integrated into the clock/calendar IC

Real Time Clock Applications

• General purpose electronic devices requiring precise timekeeping
• Industrial equipment operating in wide temperature environments
• Consumer electronics utilizing I2C communication protocols

Real Time Clock Procurement Notes

Verify the specific suffix AC0 against official Epson documentation to confirm pinout and electrical characteristics, as suffixes often denote packaging or compliance variations. Confirm availability status directly with authorized distributors, as stock levels fluctuate. Ensure the 14-SOIC footprint matches the target PCB design constraints before ordering.

Real Time Clock Selection Notes

Select this model when an I2C interface is required alongside a larger SOP-14 package for easier assembly compared to smaller footprints. The 1.7V to 5.5V operating range allows compatibility with various logic levels without additional level shifting in many standard applications. Verify that the -40°C to +85°C industrial temperature range meets the environmental requirements of the end product.

Real Time Clock Part Context

This component belongs to the RX-8025SA series of real-time clocks from Epson Timing. The 'NB' designation typically indicates specific performance or packaging variants within this family. It shares core functionalities such as I2C interface and calendar capabilities with other models in the series, differing primarily in package type and specific electrical parameters defined by the suffix codes.

Real Time Clock Replacement Considerations

Direct replacements must match the I2C interface, 14-SOIC package, and voltage range. Models like the RX-8025SA:AA0 share similar form factors but require verification of specific timing accuracy and feature sets against the original datasheet.
