The MCP795B11-I/SL is a Real Time Clock (RTC) device used to accurately track a long period of time. It is a high-performance, low-cost, low-power device that is designed for use in embedded systems, such as industrial and automotive applications, automotive entertainment systems and in power management systems.

The MCP795B11-I/SL RTC provides a wide range of features and application flexibility. It has one-second resolution timekeeping and accuracy down to 1/10 of a second, allowing for accurate timekeeping at shorter intervals. It supports a range of time formatting options, ranging from 24-hour and 12-hour formats, to include hours, minutes and seconds depending on the application. Additionally, the MCP795B11-I/SL includes an alarm and interrupts that can be set up and programmed based on specific intervals using a crystal oscillator.

The MCP795B11-I/SL also offers additional flexibility by providing a power-saving “stop” feature. The “stop” feature enables the MCP795B11-I/SL to remain in synchronized with the reference clock, even when the main power to the system is off. This feature helps reduce the overall power consumption of the device and prevents any drift or inaccuracy caused by the loss of power.

The working principle of the MCP795B11-I/SL is based on the use of a crystal oscillator. The quartz crystal is used to provide an incredibly precise timekeeping mechanism and is the basis of the device’s accuracy. When the main power of the system is provided, an oscillation within the quartz crystal is initiated, providing the main reference clock to the device. This reference clock is divided by an internal divider circuit and the MCP795B11-I/SL stores the current time information to its internal registers. This information can then be read by an external microcontroller to provide timekeeping functions.

The MCP795B11-I/SL is designed for a wide range of industrial and automotive applications that require accurate timekeeping. It has a high resolution for timekeeping accuracy and provides a low cost and low power solution that is highly reliable. Furthermore, the “stop” feature provided by the MCP795B11-I/SL ensures that the device’s timekeeping remains accurate and synchronized, even when the main power source is absent.
