Описание

The DS1306EN+ is a serial alarm Real-time Clock (RTC) provides a full binary coded decimal (BCD) clock calendar that is accessed by a simple serial interface. The clock/calendar provides seconds, minutes, hours, day, date, month and year information. The end of the month date is automatically adjusted for months with fewer than 31 days, including corrections for leap year. The clock operates in either the 24-hour or 12-hour format with AM/PM indicator. In addition, 96-byte of NV RAM are provided for data storage. An interface logic-power supply input pin (VCCIF) allows the DS1306 to drive SDO and 32kHz pins to a level that is compatible with the interface logic. This allows an easy interface to 3V logic in mixed supply systems. The DS1306 offers dual-power supplies as well as a battery-input pin. The dual-power supplies support a programmable trickle charge circuit that allows a rechargeable energy source (such as a super cap or rechargeable battery) to be used for a backup supply.

• Completely manages all timekeeping functions - 96-byte, battery-backed NV RAM for data storage
• Standard serial port interfaces with most microcontrollers
• Multiple power supply pins ease adding battery for backup
• Underwriters Laboratories® (UL) recognized
