RX8111CE A0

Real Time Clock Overview

The EPSON RX8111CE A0 is a real-time clock (RTC) integrated circuit designed for precise timekeeping and calendar functions. It features an I2C bus interface for communication with host microcontrollers. The device operates within a supply voltage range of 1.6V to 5.5V and consumes a maximum current of 3µA at 3V. It supports date formats including YY-MM-DD and time formats HH:MM:SS. The component is housed in a 10-SMD, no-lead package with dimensions of 3.2x2.5mm. It includes alarm capabilities and internal RAM for data storage.

Real Time Clock Feature Summary

Real Time Clock Procurement Notes

Verify the specific suffix 'A0' against official Epson documentation to confirm packaging or tape-and-reel specifications. Check lead times as they may vary by distributor. Ensure compatibility with existing I2C address configurations in the target system design.

Real Time Clock Selection Notes

Select this component when a compact RTC with I2C interface is required. Consider the 1.6V to 5.5V operating voltage range for flexibility in power supply design. The 10-SMD package is suitable for surface-mount assembly processes. Verify temperature range requirements against the -40°C to 85°C specification.

Real Time Clock Part Context

The RX8111CE series represents Epson's line of real-time clocks offering high accuracy and low power consumption. The 'A0' suffix typically denotes specific packaging or ordering variations within the standard RX8111CE product family. This part is distinct from printer models sharing the Epson brand.

Real Time Clock Replacement Considerations

Check for direct pin-to-pin replacements within the RX8111CE family. Verify if alternative RTCs with I2C interfaces meet the same voltage and current specifications. Confirm package compatibility before substitution.
