Resonators

RTCI2CSOP-8battery backup32.768 kHz crystalNV RAM

FRTC1338S is an SOP-8 I2C RTC with battery backup, 56-byte NV RAM, an external 32.768 kHz crystal interface, and a selectable square-wave output.

Best for

  • Battery-backed timekeeping
  • I2C embedded systems
  • Compact SOP-8 RTC designs

Avoid if

  • A confirmed 1.8 V VCC operating range is required
  • An integrated crystal is required
  • More than 56 bytes of nonvolatile RAM are needed

Check before use

  • Verify VCC requirement against the intended design rail
  • Initialize the oscillator and calendar registers
  • Check crystal layout for noise and leakage
