Industries Lowest Current Temperature Compensated I²C Real-Time Clock
Module from MICRO CRYSTAL

The RV-8803-C7 is 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.

Grenchen, Switzerland, 21. April 2015 – 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.
