Temperature Compensated I²C Real-Time Clock


Micro Crystal announced the release of the RV-8803-C7, the first Temperature Compensated RTC optimized for ultra-low power consumption to replace expensive batteries and super caps with low cost MLCC capacitors for battery backup operation.

The current consumption of 240nA and operation down to 1.5V significantly increases the operational life of backup supplies and allows for potential use of low cost MLCC capacitors as a short term backup solution. All this while providing accuracy of ±3.0 ppm (±0.26 seconds/day) over a temperature range of -40° to +85°C. In addition to the lowest current and best accuracy of all temperature-compensated RTCs, the RV-8803-C7 also has the smallest ceramic package in the industry with an integrated 32.768 KHz quartz crystal.

The RTC’s accurate timekeeping together with reliability of a power failure backup makes it ideal for a wide range of applications such as metering applications, embedded modules, data loggers, white goods, automotive, portable/wearable medical equipment and all types of POS systems.

  • Ultra-miniature ceramic SMD package: 3.2 × 1.5 × 0.8 mm
  • Integrated 32.768KHz Quartz Crystal
  • I²C interface
  • low current consumption of only 240nA
  • Very high accuracy from -40° to +85°C
  • AEC-Q200 qualified
