The PCF8563BM/TR is an SOP-8 Real-time Clock (RTC) manufactured by HGSEMI that is designed to serve as a time keeping device for a variety of embedded systems. This integrated circuit features a wide supply voltage range of 2.4V to 5.5V, supports an extended temperature range from -40°C to +85°C, has low power consumption (less than 1.2 µA in backup mode), and is RoHS compliant. The PCF8563BM/TR provides a periodic interrupt and alarms, making it suitable for applications such as the timing of data communication applications, alarming, and general-purpose applications. The device comes in a small SOP-8 package, making it suitable for applications where board space is limited.
