DS1306

Serial real -time alarm clock provides a complete BCD clock calendar, which can be accessed through simple serial interfaces. The clock/calendar provides information on seconds,, time, day, day, month, and annual information. At the end of the month, the date is automatically adjusted to less than 31 days, including the correction of the leap year. The clock runs in a 24 -hour or 12 -hour format and has an AM/PM indicator. In addition, 96 -byte non -easy loss RAMs are used for data storage.

The interface logic power supply input pin (VCCIF) allows DS1306 to drive SDO and 32 kHz pins to the level compatible with the interface logic. This allows easy interfaces with 3 volt logic in a mixed power supply system. DS1306 provides dual power and battery input pins. Dual power supports a programmable trickle charging circuit, which allows charging energy (such as super capacitors or charging batteries) as a spare power supply. The VBAT pin allows the device to back up by the non -rechargeable battery. DS1306 is fully working between 2.0 and 5.5 volts.

DS1306 provides two programming alarms of a programmable day. Each alarm can be interrupted in a programming combination of seconds, minutes, hours, and sky. If you want to ignore one under the alarm conditionsOne or multiple fields can insert the not care " state into it. It also provides 1hz and 32 kg of clock output.

DS1306 supports direct interface with Motorola SPI serial data port or standard 3 -line interface. An easy -to -use address and data format is implemented. Among them
