The MCP79402-I/ST clock is a low-power real-time clock (RTC) designed for embedded and consumer applications. It has an integrated crystal oscillator, an embedded 32.768 kHz quartz crystal, and an onboard voltage regulator. The MCP79402-I/ST clock is ideal for applications that require accurate timekeeping and information storage. The clock can remain accurate even when the primary power source fails.

The MCP79402-I/ST clock features a built-in rechargeable battery that keeps the clock running even when the main power source is off. The battery can be recharged when the main power source is available again. The MCP79402-I/ST clock also has an integrated stopwatch and timer functions and can generate multiple alarms. An I2C or SPI interface is used for communication with the host processor.

The MCP79402-I/ST clock is programmed through an external device or manually via the programming registers. The programming registers are in a serial device interface format (I2C). The clock’s programming registers are divided into multiple groups, consisting of a timekeeping register set, general-purpose register set, and some registers for other timekeeping functions.

The MCP79402-I/ST clock is designed to provide the host processor with reliable timekeeping information, as well as other relevant information, such as date and time, alarm settings, and various timer modes. The clock can be used to control the host processor’s power-saving functions, such as power-up, power-down, and other related events. The clock also offers an additional level of security by providing a programming interface for setting security and access rights.

The MCP79402-I/ST clock integrates an integrated temperature-compensated crystal oscillator that offers a high degree of timekeeping accuracy. The clock can maintain timekeeping accuracy over a wide range of temperature, shock and vibration levels. The accuracy of the MCP79402-I/ST clock is ± 1 ppm (parts per million).

The primary application field for the MCP79402-I/ST clock is in embedded applications, such as home and industrial automation, medical devices, and smart grid. It is commonly used as an alarm clock, a timer, or a time-tracking device. The clock can also be used in consumer applications, such as in portable media players, digital watches, and other gadgets. The MCP79402-I/ST clock is also frequently used in automotive applications, such as GPS tracking, fleet management systems, and vehicle diagnostics.

Overall, the MCP79402-I/ST clock is an ideal device for embedded and consumer applications that require accurate timekeeping and information storage. This clock offers a low power consumption, reliable accuracy, and a wide range of programming options. In addition, it has an integrated stopwatch, timer, and alarm functions, as well as additional levels of security.
