RX8804CE XB3

Real Time Clock Overview

The RX8804CE XB3 is a Real-Time Clock (RTC) integrated circuit manufactured by Epson Timing. It features an I2C serial bus interface for communication and supports a wide supply voltage range of 1.6 V to 5.5 V. The device provides clock/calendar functions with date formats including YY-MM-DD-dd and time formats in HH:MM:SS (24-hour). It operates within a temperature range of -40°C to +105°C and consumes a maximum current of 1.5µA to 1.6µA at 3V to 5V. The component is housed in a compact 10-SMD, no-lead package measuring 3.2x2.5 mm.

Real Time Clock Procurement Notes

Verify the specific ordering suffix 'XB3' against official Epson documentation to confirm packaging details such as reel or cut tape specifications. Ensure compatibility with the target system's I2C voltage levels given the 1.6V to 5.5V operating range. Check RoHS compliance status if required by local regulations.

Real Time Clock Selection Notes

Select this component when a low-power RTC with I2C interface is required for space-constrained designs. The 10-SMD package suits surface-mount applications. Verify that the system power supply remains within the 1.6V to 5.5V range during all operational states.
