The MCP79400T-I/ST clock/timing real-time clock is an Automotive Grade, AEC-Q100 Qualified integrated circuit designed for a variety of time keeping applications. This product combines a very low power Real-Time Clock (RTC) with a high accuracy crystal oscillator, in a small package, to offer a high performance, low power Timing solution. This product offers versatile integration with the PrimeTime™ Timing Family of Automotive Grade components, enabling customers to easily and cost-effectively add a well-defined timing hierarchy to their products.

MCP79400T-I/ST clock/timing real-time clocks are designed to operate in applications that require ultra-low power consumption and high accuracy timing solutions. Applications include car navigation systems, infotainment systems, body controllers, and energy management systems. The MCP79400T-I/ST offers an advanced power management system, a long-lasting battery backup, and an advanced crystal oscillator (XO) to ensure accurate timing even in automotive grade applications.

The MCP79400T-I/ST has two main components – the Real-Time Clock (RTC) and a crystal oscillator. The RTC is responsible for keeping accurate time while the XO is used to ensure a highly accurate timekeeping system with drift times as low as 1 ppm. The RTC is powered by an integrated ultra-low power battery backup, allowing for up to 10 years of time keeping accuracy with no external power source. The XO is used to calibrate the RTC, offering a high accuracy time keeping solution.

The MCP79400T-I/ST is designed with a low power consumption in mind. The product is designed to run on a lower supply voltage, enabling the product to minimize power consumption and extend battery life in the system. Additionally, the product has an embedded power management system, allowing the system to optimize the power consumption at all times.

The MCP79400T-I/ST offers a versatile integration with the PrimeTime™ Timing Family of Automotive Grade components. This offers customers the ability to create a well-defined timing hierarchy within their product. With the addition of a PrimeTime™ Timing Slave and a PrimeTime™ Timing Master, the customer can easily integrate an external clock source, and adjust their system\'s clock rate, timing resolution, and other parameters to suit the application.

In addition to its clock and timing capabilities, the MCP79400T-I/ST also provides advanced security features such as SecureBoot, CommKey and Secure Component Lock. SecureBoot ensures that only authorized firmware can be loaded into the system, protecting it from malicious actors. CommKey ensures secure communication between the microcontroller and the device. Secure Component Lock ensures that the functionality of the device is only accessible to authorized users.

The MCP79400T-I/ST is an ideal choice for automotive and other applications requiring accurate, low-power time keeping solutions. The product combines a low power Real-Time Clock (RTC) with a high accuracy crystal oscillator in a small package. The product also offers a secure and reliable power management system, a long-lasting battery backup and a secure environment through advanced security features.
