10.1×7.4×3.2mm real-time clock module only draws 130nA typical
14.00
With a 0.33F supercapacitor, the 10.1×7.4×3.2mm chip can operate for 16 weeks. According to the manufacturer, the RX6110SA achieves an operating current that is half that of leading competitors by employing special low-power circuit design techniques and Epson’s unique low-leakage IC process technology.
Compared to microcontroller implementations, Epson’s RX6110SA can operate eight times longer. The RX6110SA also includes a diode-less power-supply switching circuit which allows it to operate and charge from power supplies ranging from 5 V down to as low as 1.1V. In addition to keeping time, real-time clocks are used to log power-loss events and save system state when power is lost. Epson’s RX6110SA offers a rich feature set to support these needs, including a 32.768 kHz output, alarms and timers, and RAM. The RX6110SA supports both SPI-bus and I2C-bus interfaces.
