The DS1340C-3# is an integrated circuit (IC) component manufactured by Maxim Integrated. It is a real-time clock (RTC) module that provides highly accurate timekeeping and calendar functionality to electronic devices.
One of the key features of the DS1340C-3# is its ability to maintain accurate time even in the absence of power. It has an internal lithium battery that can power the clock and calendar functions, ensuring that accurate time information is always available. This is particularly useful in applications where the device may be powered off for extended periods, such as in alarm systems or IoT devices.
The DS1340C-3# supports a wide range of timekeeping formats, including 12-hour and 24-hour time formats, as well as day, month, and year information. It also includes leap year compensation, so it can accurately handle leap years without manual intervention.
Another important feature of the DS1340C-3# is its programmability. It includes an I2C serial interface, which allows for easy communication with a microcontroller or other host devices. This interface enables the user to set and adjust the time and calendar settings, as well as perform other control functions.
The DS1340C-3# also offers a variety of alarm functions. It has two programmable time-of-day alarms that can trigger interrupt signals or wake-up signals to enable specific actions or events. These alarms can be set to trigger at specific times or repeated at regular intervals
