Resonators

RTCSPIIntegrated crystalTemperature compensated3225 package

SD8840 is a 10-pin 3225 real-time clock IC with an integrated crystal, digital temperature compensation, SPI control, alarms, countdown timing, and frequency output.

Best for

  • Embedded real-time clock functions
  • SPI-controlled timekeeping
  • Applications requiring integrated crystal compensation

Avoid if

  • An interface other than 4-wire SPI is required
  • A package other than 3225 is required

Check before use

  • Supply and backup or timekeeping voltage
  • SPI clock polarity and timing
  • Alarm, countdown, and interrupt requirements
  • PCB layout and reflow soldering constraints
