The DS1315E-33+ is an IC (Integrated Circuit) component that offers a real-time clock (RTC) solution with a non-volatile memory (NVRAM). It is commonly used in applications where accurate timekeeping is essential, such as data logging systems, instrumentation, and industrial equipment. The DS1315E-33+ is manufactured by Maxim Integrated.
One of the key features of the DS1315E-33+ is its ability to provide accurate timekeeping even in the absence of power. It contains a built-in lithium energy source that can power the clock and memory for an extended period without the need for an external power supply. This feature is particularly useful in environments where power failures or disruptions are common.
The DS1315E-33+ utilizes a 32kHz quartz crystal oscillator to maintain accurate timekeeping. It incorporates an internal divide-by-256 counter that generates timekeeping signals with a resolution of one second. The RTC circuitry within the DS1315E-33+ is designed to compensate for crystal frequency deviations over time, ensuring consistent and precise timekeeping.
In addition to real-time clock functionality, the DS1315E-33+ also provides non-volatile memory storage. It has 32 kilobits of non-volatile SRAM (NVSRAM), which allows data to be retained even when power is disconnected. This makes it suitable for applications where critical data needs to be preserved in the event of an unexpected power loss
