Real Time Clock (RTC)
A real-time clock (RTC) is a computer clock (most often in the form of an integrated circuit) that keeps track of the current time.
Product & engineering
Understand the product.
A real-time clock (RTC) is a computer clock (most often in the form of an integrated circuit) that keeps track of the current time.
Although the term often refers to the devices in personal computers, servers and embedded systems, RTCs are present in almost any electronic device which needs to keep accurate time. Meanwhile, with the improvement of technical, the new RTC possesses more complex functions, and the bulk became much more tiny (2mm×2mm×0.85mm). Electronic devices utilize real time clock modules to serve the purpose of tracking current time, one real time clock module is normally a circuit containing real time clock chip, capacitance, diode and so on. This report only focuses on Real Time Clock Chip, which is the product shown below. Since the manufacturers refer these chips as RTC（Real Time Clock），this report uses the same addressing. Therefore, when the report mentions real time clock in the following chapters, the report only refers to the chip, not the module.
