The PT7C4563BUEX is a low-power real-time clock (RTC) from Quarktwin Technology Ltd. designed for applications requiring accurate timekeeping and calendar functions. It operates with an external 32.768 kHz quartz crystal and supports high-ESR crystals up to 100 kOc. The device communicates via a 2-wire I¬=C bus, supporting high-speed mode at 400 kHz. This RTC includes features such as a programmable square wave output, time and calendar counters (in BCD format), and an oscillator stop flag. It provides a low backup current of approximately 400 nA at 3.0V and operates within a voltage range of 1.3V to 5.5V. The device is suitable for a wide temperature range from -40¬8C to 85¬8C, making it versatile for various environmental conditions. The PT7C4563BUEX is available in multiple package options, including MSOP-8, which facilitates integration into compact designs. Its automatic date adjustment for months with fewer than 31 days and leap year corrections enhance its functionality for time-sensitive applications.
