Description
This ultra small RTC Module has been specially designed for miniature and
cost sensitive high volume applications.
The SMT ceramic package combines the 32.768kHz crystal unit with the
CMOS-based oscillator and real-time-clock circuitry. The clock function
provides tenths/hundredths of seconds, seconds, minutes and hours. The
calendar function tracks date, month, year and century with automatic
leap year compensation. Programmable CLKOUT frequencies, alarm
settings and watchdog function increase flexibility.
