CBM1307 OPERATION INSTRUCTION FEATURES  GENERAL DESCRIPTION CBM1307 is essentially the binary – Count of seconds, minutes, hours, week days, date, months and years decimal digital watch with a calendar, it has with the consideration of the leap years (before 56 bytes of the power self-sufficient static RAM and possesses the 2100);  additional low power consumption. The addresses and 56 bytes of the power self-sufficient RAM data for the data storage; are applied consecutively via the two-wire bi-directional bus. The microcircuit  Two-wire consecutive interface;  Programmable rectangular output signal; minutes and seconds, count of week days,  Automatic determination of the supply date, month and year. The last day of the voltage drop and the switching diagram; month is automatically adjusted for the Consumption of less than 500nА in the months of less, than 31 days, including  is intended for count of the real time in hours, correction for the leap year. The watches back-up supply mode with the operating function in the 24-hour format or in the generator;  Temperature range of the 12-hour format with the AM / PM-indicator. industrial CBM1307 has the built-in power supply application: -40℃ – +85℃  control circuit, which determines the supply Accuracy is better than ±1 minute per disruption and automatically switches over month the device into the battery mode.
