Extensive range of real time clocks to cater for all requirements.

Supplier: Epson

Epson logo

Technology type: Real Time Clocks

Epson’s extensive range of real time clocks should cater for all requirements. With their built in 32.768kHz watch crystal these RTCs cover all interfaces and have a wide choice of added features to choose from. With high stability , extended temperature products and those with low back up voltage and low current consumption the portfolio will ensure applications stay on time..

RX8111CE and RX4111CE (3.2x2.5mm) are new to the family. Available in I²C/SPI these small packages have the lowest current consumption and are packed with additional features including event detection.

 RX8804CE and RA8804CE are 3.2x2.5mm too but as temperature compensated offer high stability to ±1.9ppm /0+50ºC. As automotive qualified the RA8804CE can provide ±8ppm/-40+105ºC

RX6110SA (10.1x7.4mm) loaded with functionally but with the added feature of battery power switching. Low 130nA typical current consumption, 5±23ppm/+25ºC tolerance makes it a solid member of the line up.
