I²C RTCDTCXO32.768 kHzalarm interruptwake-up timerbattery backup

RX8900CE UA is a compact EPSON I²C RTC with an integrated temperature-compensated 32.768 kHz oscillator and specified ±3.4 ppm stability over -40 °C to +85 °C.

Best for

  • Low-power clock and calendar retention
  • I²C systems requiring temperature-compensated timing
  • Wake-up timer or alarm interrupt functions

Avoid if

  • A confirmed RoHS, REACH, lifecycle, or MSL declaration is mandatory and cannot be obtained separately
  • The application requires I²C access while the device is in backup mode

Check before use

  • Confirm full EPSON ordering suffix and package compatibility
  • Confirm VDD and VBAT power-switching behavior
  • Verify startup and VLF initialization handling
