MCP79412-I/ST

The MCP79412-I/ST is a 41-pin device from Microchip Technology that is part of a family of integrated circuits referred to as Real Time Clocks (RTCs). RTCs measure time and date with precision, and its applications range from data logging and tracking to providing time stamps for important events. The MCP79412-I/ST is an especially powerful device, as it features a battery backup and a USB interface, making it a robust and versatile solution for keeping accurate time.

The workings of RTCs are based on dedicated hardware components that rely on crystal oscillators as well as other electrical components. The oscillator, typically quartz-based, generates a steady and highly accurate frequency, allowing the microcontroller to keep track of time. The MCP79412-I/ST is powered by two power sources: a main power supply, which can be either 3V or 5V; and an lithium ion battery, which is responsible for supplying power when the main supply is not present. The device also has an integrated EEPROM, which is capable of storing up to 40 bytes of data, further increasing its functionality.

The major features of the MCP79412-I/ST include an Integrated USB Transceiver (ITC) which allows users to communicate with the device over a standard USB interface, without needing a dedicated development board. This form of communication enables the MCP79412-I/ST to be used with microcontroller platforms such as the AVR and PIC. Additionally, the device also features a real-time clock (RTC), which is capable of providing accurate time and date data, as well as a quartz-based oscillator. This enables the device to provide precise timekeeping, even when the main power supply is cut off.

The main application of the MCP79412-I/ST is as an accurate and reliable real time clock, which is suitable for a variety of applications. The device can be used in tracking and data logging systems, as its dual power source ensures that data is not lost in the event of power failure. Additionally, the device’s USB interface can be used to provide time stamps for important events, making it perfect for mission-critical applications.

In summary, the MCP79412-I/ST is an integrated circuit from Microchip Technology that is part of a family of devices known as Real Time Clocks. The device features a quartz-based oscillator, a real-time clock, a lithium ion battery and integrated USB transceiver, making it a powerful and versatile solution for keeping accurate time. The device can be used for a variety of applications, such as tracking and data logging, as well as providing time stamps for important events.
