Real Time Clock datasheet and documents for RX8901CE XB B03

RX8901CE XB B03

Real Time Clock Overview

The EPSON RX8901CE XB B03 is a Real-Time Clock (RTC) module featuring an I2C bus interface. It integrates a 32.768 kHz crystal with a frequency tolerance of ±5 ppm across the operating temperature range of -40°C to +85°C. The device operates within a supply voltage range of 1.6 V to 5.5 V and consumes low power, specified at 0.24 µA in backup mode. It provides timekeeping data in YY-MM-DD-dd and HH:MM:SS formats without battery backup switching. The component is housed in a compact 3.2 x 2.5 x 1.0 mm package.

Real Time Clock Feature Summary

I2C Bus Interface for digital communication
Integrated 32.768 kHz high-stability crystal
Low power consumption of 0.24 µA
±5 ppm frequency accuracy (-40°C to +85°C)

Real Time Clock Applications

Industrial control systems requiring precise timing
Consumer electronics with real-time clock needs
Data logging devices

Real Time Clock Procurement Notes

Verify the specific suffix 'B03' against official Epson documentation to confirm pin configuration and packaging details, as distributor listings often reference similar variants like 'B06'. Ensure compatibility with system voltage levels between 1.6 V and 5.5 V. Confirm availability through authorized channels due to potential manufacturing lead times.

Real Time Clock Selection Notes

Select this model for applications requiring high accuracy (±5 ppm) and low power in a small footprint. Compare with the RX8900 series if battery backup switching or different temperature ranges are required. Ensure the design accommodates the 10-pin ceramic package dimensions of 3.2 x 2.5 x 1.0 mm.

Real Time Clock Part Context

The RX8901CE belongs to Epson's family of high-precision RTC modules. The 'XB' designation indicates the ±5 ppm accuracy grade over the industrial temperature range. This series is designed to replace traditional discrete RTC solutions by integrating the crystal oscillator directly into the package.
