RA-8565SA:B PURE SN

Real Time Clock Overview

The RA-8565SA:B PURE SN is a Real Time Clock (RTC) IC manufactured by Epson Timing. It integrates a clock/calendar function with an I2C interface, housed in a 14-SOP package. The device operates within a supply voltage range of 1.8V to 5.5V and supports time formats including HH:MM:SS and YY-MM-DD-dd. It features an alarm function and consumes between 1µA and 1.8µA at 3V to 5V. The component is rated for industrial temperatures from -40°C to 125°C and complies with RoHS3 standards.

Real Time Clock Feature Summary

• I2C interface for digital communication
• Integrated clock/calendar with alarm capability
• Wide operating voltage range (1.8V ~ 5.5V)
• Industrial temperature rating (-40°C ~ 125°C)

Real Time Clock Applications

• Data logging systems requiring precise timekeeping
• Consumer electronics with calendar functions
• Industrial control equipment needing RTC synchronization

Real Time Clock Procurement Notes

This component is officially listed as End-of-Life (EOL). Distribution availability is limited or non-existent through standard channels. Verification of current stock status with authorized distributors is required before procurement planning. Alternative sourcing strategies should be considered due to the discontinued status.

Real Time Clock Selection Notes

Designers must verify compatibility with the target system's I2C bus voltage levels, given the 1.8V to 5.5V operating range. The 14-SOP package dimensions require adequate PCB space allocation. Current consumption specifications should be evaluated against battery-backed power constraints in low-power applications.

Real Time Clock Part Context

This part belongs to the RA-8565SA series of real-time clocks. It shares functional similarities with other Epson RTC models but is distinguished by its specific package type and interface configuration. The series is designed for general-purpose timekeeping applications in embedded systems.

Real Time Clock Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the EOL status, engineers should consult Epson Timing for recommended replacement components or evaluate third-party compatible RTCs with matching I2C interfaces and package footprints.
