The MCP79401-I/SN is a low-cost, low-power 32-bit Real Time Clock (RTC) designed to provide a source of time and date information for a variety of applications. It is the first RTC solution to combine both a high-performance RTC core with a fully-integrated high-accuracy, low-power and low-jitter oscillator.

The MCP79401-I/SN RTC is designed to be used as an individual module in a system, and is designed to work with either an external or internal battery. It provides excellent temperature drift characteristics, making it ideal for a wide range of industrial and automotive applications. It is also suitable for use in wireless and IoT applications where high accuracy and low power are needed.

The MCP79401-I/SN RTC features a unique dual-stage oscillator design that utilizes a high-accuracy high-stability crystal, as well as an ultra-low-power power oscillator to keep the time base accurate and stable. This design allows for a wide range of accuracy levels, from 0.001 seconds to 30 seconds, and allows for a wide range of power consumption levels, from 0.1 µA to 6 µA.

The RTC is designed to work in both standalone and system modes. In standalone mode, the RTC is powered by the external battery or the on-boardinternal coin cell battery. It is capable of self-starting and will continue to operate even if power is momentarily lost. In system mode, the RTC is powered directly from the host system\'s power supply and is synchronized with the host. This allows the RTC to use the system\'s power source to control its timekeeping instead of relying on the slower and less accurate internal battery.

The RTC includes a full featured time and date calendar, with power-on-reset, digital calibration, and a variety of other features. It also includes a wide range of alarm functions, including programmable alarm sources, min/max temperature alarm, and upcoming alarm functions.

The MCP79401-I/SN RTC is pin compatible with industry-standard RTC devices, and is available in 5 different packages. It is supported by a wide range of software APIs for managing and controlling the RTC and its features.

The MCP79401-I/SN RTC is ideally suited for a wide range of industrial and automotive applications, including automotive displays and audio systems, GPS systems, personal computers, routers and switches, medical devices, and many other applications that require accurate and reliable timekeeping.

The MCP79401-I/SN RTC is a powerful and cost-effective solution for any application requiring an accurate and reliable real time clock. With its low power consumption, wide temperature operating range, wide range of accuracy levels, and wide range of features and alarms, it is an ideal choice for any product or system requiring accurate and reliable timekeeping.
