Low-Current Real-Time Clock Module

Low power real-time clock (RTC) module with typical current consumption of just 130 nA. Epson’s RX6110SA current consumption level is 35% lower than that of the RX-8571SA. Epson’s RX6110SA enables the reduction of hazardous substances by allowing electronic device makers to replace batteries with supercapacitors. With a 0.33F supercapacitor, The module can operate for 16 weeks and achieves an operating current one half of leading competitors by employing special low-power circuit design techniques and Epson’s unique low-leakage IC process technology.
