Working Principle

The MCP795B22-I/ST Real Time Clock utilizes an internal oscillator to time the clock with very low power consumption. It operates from a 3V or 5V supply, and can be configured to either drive or receive external clock or data signals. The device is capable of driving and receiving one clock stop pulse or external clock from another RTC device out of the MCP795B22-I/ST. Furthermore, the MCP795B22-I/ST is able to measure external clock pulses with a frequency of up to 1MHz.

The MCP795B22-I/ST can be configured to measure temperature by utilizing its integrated 32kHz crystal. This crystal can be used to measure external temperature to an accuracy of 0.25°C using standard internal Digital-to-Analog Converter (DAC) calculations. Additionally, the MCP795B22-I/ST can also be coupled with an external temperature sensor such as the MCP902s/s/s.

The MCP795B22-I/ST can be programmed to provide several timekeeping functions such as Alarm, Timer and Interrupt. The Alarm can be used to generate an interrupt or timer expire at specified times, while the Timer and Interrupt functions can be used to control external events such as sample rate changes of an external analog to digital converter. All these functions can be programmed to an accuracy of ±1 minute.

The MCP795B22-I/ST can be monitored with an I2C interface. This allows the user to monitor the RTC status and values from an external computer or micro-controller. The I2C interface is also used to configure parameters such as clock rate and memory enables.

In summary, the MCP795B22-I/ST Real Time Clock offers high precision timing and temperature measurement solutions for a wide range of embedded applications. It can be configured to drive and receive external clock and data signals and measure external temperature with a high degree of accuracy. It is also able to provide several timekeeping functions such as alarm, timer and interrupts, which are all programmable with an accuracy of ±1 minute. Finally, the device can be monitored with an I2C interface, allowing the user to control and monitor the RTC from an external computer or micro-controller.
