PT7C4372C Description
PT7C4372A/C are I2C bus interface-pliant 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....
