FRTC4100S

Clock/Timing - Real Time Clocks

RTCI2Ccalendarbattery backupSOP-832.768 kHz

FRTC4100S is an SOP-8 I2C RTC/calendar for low-power embedded timekeeping with VBAT backup switchover and a 32.768 kHz crystal interface.

Best for

  • Battery-backed embedded clocks
  • Low-power calendar and timestamp functions

Avoid if

  • A documented compliance or lifecycle status is mandatory
  • An integrated crystal oscillator without an external crystal is required

Check before use

  • Use a 32.768 kHz crystal with suitable load capacitance and series resistance
  • Ensure SDA and SCL have pull-up resistors
  • Check VCC-to-VBAT switchover behavior at the intended supply voltage
