MCP795B20T-I/SL

The MCP795B20T-I/SL is a Real Time Clocks device, it is an important component of a mission-critical system such as a personal computer. A Real Time Clock (RTC) is a hardware device that stores time and date information and is especially useful in applications that need to keep track of time. The MCP795B20T-I/SL device is a tiny RTC with a rugged low-power design, providing a full-featured clock with an integrated temperature-sensing circuit. It supports both SPI/QSPI and I2C interfaces, allowing flexible configuration of communication protocols.

Application field

The MCP795B20T-I/SL has many application fields. It can be used in a wide range of consumer and industrial electronic products such as digital televisions, DVD players, electronic games, satellite receivers, VoIP products, automated test equipment, networking and storage equipment and PC motherboards. It can also be used as a timing device in automotive applications such as automotive infotainment systems, vehicle tracking and navigation devices, and vehicle infotainment displays.

Working principle

The MCP795B20T-I/SL device is based on a programmable oscillator and a temperature-sensing circuit that can be used to accurately measure elapsed time. The programmable oscillator operates at a frequency of 32.768 kHz, which is ideal for applications that need to keep track of time. The temperature-sensing circuit allows the device to accurately measure temperatures and make calculations based on that data. The device is also able to automatically adjust to changes in temperature and make periodic corrections to its timing.

The MCP795B20T-I/SL also features an on-chip RAM with a 6-bit time and date counter. The time and date counter keeps track of the current time and date, which can be accessed and programmed by the user. The on-chip RAM also includes alarm registers, which can be programmed to trigger an alarm at a specified time or date. Finally, the device also supports multiple wake-up sources, including real time wake-up, external interrupt wake-up, and auto-wake-up.

The MCP795B20T-I/SL is an excellent choice for applications requiring a reliable and accurate time reference. It is also ideal for applications that require low power consumption and robust operation in extreme environments. The device is available in both commercial and automotive grade, allowing it to be used in a wide range of applications.
