DS1372U+

The DS1372U+ is an I2C, 32bit, binary counter clock with 64bit ID in 8 pin µSOP package. It is a 32bit binary up counter and 24bit down counter with a unique 64bit ID. The 32bit binary counter designed to continuously count time in seconds and an additional counter is provided that can generate a periodic alarm. An interrupt output can be driven when the alarm condition is met. The device includes a unique, factory lasered 64bit ROM ID. The counters, ID, configuration and status registers are accessed using an I2C serial interface. The DS1372 includes a SQW/INT open drain output that can output either a square wave at one of four predefined frequencies or it can output an active-low signal when the 24bit down counter reaches 0.
