PRECISE REAL TIME CLOCK HAS WORLD’S LOWEST CURRENT DRAIN
For applications requiring ultra-low power consumption, Micro Crystal has introduced a SMD package real time clock (RTC) that typically draws just 130nA @ 3.0V. The RV-2123-C2 is ideal for compact portable devices, especially where a super capacitor is used for backup supply operation. Its ultra-wide 1.1V to 5.5V operating range provides added flexibility. Communications with other circuitry is simplified by an SPI-Bus® (SCL up to 8 MHz @ 5.0V).
