  • Description

    The CDP1879 real-time clock supplies time and calendar information from seconds to months in BCD format. It consists of 5 separately addressable and programmable counters that divide down an oscillator input. The clock input can have any one of 4 possible frequencies, allowing flexibility in the choice of crystal or external clock sources. Using an external 32kHz clock source, timekeeping can be performed down to 2.5V (see Standby (Timekeeping) Voltage Operation).
