The RTC-63423B is a Real Time Clock (RTC) device designed as a single time-keeping IC and manufactured by Ricoh, a major electronics manufacturer. The RTC-63423B is widely used for design solutions requiring precise time-keeping, such as embedded systems, industrial automation and control applications, medical devices, military and aerospace applications, home theater and entertainment systems, automotive and battery powered applications, and a wide variety of other applications. RTC-63423B is the perfect choice for a powerhouse RTC for modern designs that demand energy efficiency and reliability.

The RTC-63423B supports several features to ensure reliability and accuracy. It has an accurate time-keeping of ±1 PPM accuracy, ±1 ms per day drift rate, adjustable output frequency from 1 Hz to 1 MHz, programmable frequency proportional to temperature, dynamic frequency compensation to keep timekeeping with the dynamic temperature, and an 8-bit counting resolution. It also boasts a low power consumption of 2 mW in the standby mode. In addition, it has a very low jitter of 100 ns or better, and a wide operating temperature range of -40°C to +85°C.

The RTC-63423B has a wide range of features and functions that make it suitable for a variety of applications. It can support several operating modes, such as synchronized free running, self-calibration, and frequency drift compensation, which makes the RTC-63423B an ideal option for applications that often require higher accuracy and reliability. The device also has an internal power supply, so there is no need for an additional power supply or a backup battery when using the device in an application.

The working principle employed by the RTC-63423B follows the fundamental principles of how RTC devices operate. It receives a 48MHz clock source from an external source—often from the system’s main oscillator—and uses a programmable divider to divide the incoming frequency into output frequencies that range from 1Hz to 1MHz. It also uses an internally generated oscillator to establish a base clock frequency and to perform dynamic frequency compensation, which is used to adjust the output frequencies to generate accurate timing data in response to temperature changes. This allows the device to maintain its accuracy over time and in different environments, thus making it a suitable choice for applications that require extreme accuracy and reliability.

The RTC-63423B provides many advantages to users. Its ability to accurately measure and adjust time helps to prevent minor timing inaccuracies that could lead to problems with other system components, leading to enhanced reliability and accuracy of the overall system. Additionally, its low power consumption further enhances its desirability in battery-powered applications. Finally, its wide operating temperature range ensures that it can be used in a range of environments. As such, the RTC-63423B is an ideal choice for a wide variety of applications requiring reliable and accurate timekeeping.
