Ordering Information

 Standard.  Optional - Please specify required code(s) when ordering Specifications  Available on T&R - 1k or 3k pcs per reel  Evaluation / development board & manual av ailable on request  The I2C-Bus is a trademark of Philips Electronics NV Block Diagram This RTC IC has been specially designed to achieve an ultra-low power consumption of typically 130nA @ VDD 3.0V in time-keeping mode. It combines a 32.768kHz crystal unit with a CMOS based oscillator and real- time clock circuit. The calendar function tracks year, month, date and day of the week with built-in century and leap-year flags. The clock function tracks minutes and seconds in 24-hour format. Programmable alarm setting, dual timer functions and integrated switchover circuitry increase flexibility.  Manufactured by Micro Crystal  Stocked & distribut ed by Golledge
