0 V (Typ.
) Product Description PT7C4372A/C are I2C bus interface-compliant real-time clocks that have been adjusted for high precision.
In addition to providing a function for generating six types of interrupts, a dual alarm function, an oscillation stop detection function (used to determine presence of valid internal data at power-on), they includes a digital clock precision adjustment function that can be used to set various levels of precision.
Since the internal oscillation circuit is driven at a constant voltage, 32-kHz clock output is stable and free of voltage fluctuation effects.
Table 1 shows the diverse functions of the two RTC circuits.
