RX-8025NBAC3 PURE SN

Real Time Clock Overview

The RX-8025NBAC3 PURE SN is a Real Time Clock (RTC) IC manufactured by Epson Timing. It features 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 operates within a supply voltage range of 1.7V to 5.5V and consumes a maximum current of 1.2µA to 1.8µA at 3V to 5V. It supports an operating temperature range of -40°C to 85°C and is housed in a 14-SOIC package.

Real Time Clock Feature Summary

• I2C Bus Interface for digital communication
• Clock/Calendar functionality with alarm feature
• Low power consumption (1.2µA ~ 1.8µA @ 3V ~ 5V)
• Wide operating voltage range (1.7V ~ 5.5V)

Real Time Clock Applications

Real Time Clock Procurement Notes

Verify component authenticity through authorized Epson distributors. Confirm RoHS compliance status prior to procurement. Check for end-of-life notifications as discontinuation may affect long-term availability. Ensure packaging specifications match production line requirements.

Real Time Clock Selection Notes

Select this model when an I2C interface is required for RTC functions. Verify that the 14-SOIC package fits the PCB layout constraints. Ensure the operating voltage range of 1.7V to 5.5V aligns with the system power supply. Consider the -40°C to 85°C temperature range for environmental suitability.

Real Time Clock Part Context

This part belongs to the Epson RX-8025SA series of real-time clocks. It shares functional similarities with other variants in the family, differing primarily in packaging, accuracy specifications, and specific ordering suffixes. The NBAC3 suffix indicates specific manufacturing or packaging details defined by Epson.

Real Time Clock Replacement Considerations

Direct replacements should be sought from the Epson RX-8025SA series. Cross-referencing with other I2C RTCs requires verification of pin compatibility and register mapping. No specific substitute part numbers are confirmed in public documentation.
