RX-4035SA:AA3 PURE SN

Real Time Clock Overview

The Epson RX-4035SA:AA3 is a Real-Time Clock (RTC) component belonging to the RX-4035SA series. It provides timekeeping functions with support for I2C and SPI bus interfaces. The device operates within a supply voltage range of 1.6 V to 5.5 V and maintains functionality across an industrial temperature range of -40°C to +85°C. It features a surface-mount package design suitable for automated assembly processes.

Real Time Clock Feature Summary

• Supports multiple serial communication protocols including I2C and SPI
• Operates on a wide voltage range from 1.6 V to 5.5 V
• Industrial temperature rating spanning -40°C to +85°C
• Surface-mount technology (SMD/SMT) compatible packaging

Real Time Clock Applications

• Data logging systems requiring precise timestamping
• Network equipment needing synchronized clock signals
• Industrial control units operating in variable temperatures

Real Time Clock Procurement Notes

Verify the specific suffix :AA3 against official Epson documentation to confirm exact tape-and-reel specifications or binning codes. Ensure interface configuration matches system requirements, as this model supports both I2C and SPI modes. Confirm voltage levels align with the target circuit's power domain before integration.

Real Time Clock Selection Notes

Select this component when a wide operating voltage range and robust industrial temperature stability are required. The dual-interface capability allows flexibility in PCB layout and microcontroller selection. Verify that the chosen package variant fits the available board space and soldering profile constraints.

Real Time Clock Part Context

This part belongs to the Epson RX-4035SA family of real-time clocks. These components are designed for applications demanding high accuracy and low power consumption. The SA designation typically indicates specific package and performance characteristics within the broader RX series lineup.

Real Time Clock Replacement Considerations

Direct substitutes must match the I2C/SPI interface compatibility and the 1.6V–5.5V operating range. Check pinout definitions carefully, as alternative RTCs may differ in register mapping or address configurations.
