### Overview

C5505 includes a Real Time Clock (RTC) with its own separated power supply and isolation circuits. The separate supply and isolation circuits allow RTC to run while the rest of the C5505 device is powered off. All RTC registers are preserved and the counter continues to operate when the C5505 device is powered off. The RTC also has the capability wakeup the Power Management and apply power to the rest of the C5505 through an alarm, periodic interrupt, or external WAKEUP signal. The RTC includes the following features: Time Information (seconds, minutes, and hours) in binary codec decimal(BCD), 24 hour mode,millisecond time correction Calendar Information (day, month, and year) in BCD,100-year calendar, up to the year 2099,leap year compensation.

Interrupt generation,Periodic interrupt: every millisecond, second, minute,hour Alarm interrupt: precise time of day. 32KHz Oscillator with frequency calibration.
