Micro Crystal – RV-8803-C7 Module



The RV-8803-C7 Module is the first high accuracy / temperature compensated RTC optimized for ultra-low power consumption in a tiny package.

The ultra-low current consumption of 240 nA and low operating voltage down to 1.5 V significantly increases the operational life of backup supplies and allows for potential use of low cost MLCC capacitors instead of costly batteries or supercaps 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. Development tools: Demo boards and Graphical user interface are ready to support design-in.

The RTC’s accurate timekeeping in combination with its ultra-low power consumption allowing for simple power supply backup makes it ideal for a wide range of functions such as metering applications, embedded modules, data loggers, white goods, automotive, portable/wearable medical equipment and all types of POS systems.
