RX-8803SA:UA PURE SN

Real Time Clock Overview

The RX-8803SA:UA PURE SN is a Real Time Clock (RTC) manufactured by Epson Timing. It utilizes an I2C bus interface for data communication and supports standard date formats including YY-MM-DD-day-of-week and time formats in HH:MM:SS (24-hour). The device operates within a supply voltage range of 1.6 V to 5.5 V and functions reliably across a temperature range of -40°C to +85°C. It features a low power consumption profile suitable for battery-backed applications, though it does not include a dedicated backup switching mechanism. The component is designed for surface mount installation.

Real Time Clock Procurement Notes

Verify the specific suffix :UA against official Epson documentation to confirm pinout and package variations. Ensure compatibility with system I2C pull-up resistor values. Confirm RoHS compliance status through the manufacturer's current declaration before finalizing procurement orders.

Real Time Clock Selection Notes

Select this component when an I2C-compatible RTC is required for designs supporting voltages down to 1.6 V. Verify that the application environment stays within the specified -40°C to +85°C operational limits. Check if the absence of a hardware backup switch meets the system's power management strategy.

Real Time Clock Part Context

This part belongs to the RX-8803LC family of real-time clocks from Epson Timing. These components are widely used in embedded systems where accurate time tracking is essential without the need for complex external timing circuits. The SA variant typically denotes specific package or tape-and-reel configurations.

Real Time Clock Replacement Considerations

Direct replacements may include other Epson RX-8803 variants with compatible I2C interfaces. Verify pin-to-pin compatibility and electrical specifications before substituting. Cross-reference with major distributors for availability of equivalent RTC ICs.
