Programmable alarm, timer and interrupt Low power consumption, low ageing Block Diagram Available on T&R - 1k or 3k pcs per reel. Evaluation / development board & manual available on request The I2C-Bus is a trademark of Philips Electronics NV 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.
