RX8901CE XS A06

Real Time Clock Overview

The RX8901CE XS A06 is a Real-Time Clock (RTC) IC from Epson Timing, designed for high-precision timekeeping in surface-mount applications. It features an I2C bus interface and operates within a voltage range of 1.6 V to 5.5 V. The device incorporates a built-in crystal oscillator with a frequency tolerance of ±3.0 ppm across the -40°C to +85°C temperature range. Current consumption is specified at 1.5 µA @ 3V. The component is housed in a 10-SMD, no-lead package measuring 3.2 x 2.5 mm. It supports standard date formats (YY-MM-DD) and time formats (HH:MM:SS), including alarm functions.

Real Time Clock Feature Summary

• High precision ±3.0 ppm frequency tolerance (-40°C to +85°C)
• Low power consumption of 1.5 µA at 3V
• I2C bus interface for digital communication
• Integrated backup switching capability

Real Time Clock Applications

• Portable electronic devices requiring precise timekeeping
• Industrial equipment operating in wide temperature ranges
• Data logging systems needing timestamp accuracy

Real Time Clock Procurement Notes

Verify the specific suffix 'A06' indicates the reel packaging quantity of 2000 units per manufacturer standards. Confirm availability status as distribution channels may report limited stock or regional restrictions. Ensure compatibility with existing I2C bus voltage levels before integration.

Real Time Clock Selection Notes

Select this model when ±3.0 ppm accuracy is required over the commercial/industrial temperature range. Compare against XB variants if ±5.0 ppm tolerance suffices for cost reduction. Verify that the 10-SMD footprint matches the PCB layout constraints and that the I2C address configuration meets system requirements.

Real Time Clock Part Context

This part belongs to the RX8901CE series of real-time clock modules. It shares the same physical package and core functionality with other suffixes like A0B (bulk) or B06 (different pin function). The 'XS' designation specifically denotes the tighter ±3.0 ppm frequency stability compared to the 'XB' series.

Real Time Clock Replacement Considerations

Direct substitutes include other RX8901CE variants such as RX8901CE XB A06 for relaxed tolerance needs. Cross-reference with RX8900CE series for similar I2C RTC functionality, noting potential differences in backup switching or voltage ranges.
