About This Product
■Summary
R2221 is a 2-wire serial interface (I2C bus) real-time clock IC. Connection with the host is made using two signal lines (SCL, SDA). 6 types of interrupt generation functions, 2 systems of alarm functions, oscillation stop detection function that can be applied to determine data validity at power-on, etc., power supply voltage monitoring function, 32kHz clock output for subclock of external microcontroller (CMOS output, control (with terminal) function, and a digital clock error correction function that allows the clock to be set with high precision.
Furthermore, since the oscillation circuit is driven at a constant voltage, there is little voltage fluctuation in the oscillation frequency, achieving ultra-low current consumption (Typ. 0.18 μA at 3V). All the resistance and capacitance for the oscillation circuit are built-in, so oscillation can be performed simply by connecting an external crystal resonator. Packages include TSSOP10G and small QFN018018-12.
