DESCRIPTION
The DS1306 Serial Alarm Real Time Clock provides a full BCD clock calendar which is accessed via 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 less 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 bytes of nonvolatile RAM are provided for data storage.
An interface logic power supply input pin (VCCIF) allows the DS1306 to drive SDO and 32 kHz pins to a
level that is compatible with the interface logic. This allows an easy interface to 3-volt 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 which allows a rechargeable energy source (such
as a super cap or rechargeable battery) to be used for a backup supply. The VBAT pin allows the device to
be backed up by a non-rechargeable battery. The DS1306 is fully operational from 2.0 to 5.5 volts.
Two programmable time of day alarms are provided by the DS1306.
Each alarm can generate an
interrupt on a programmable combination of seconds, minutes, hours, and day. “Don’t care” states can be
inserted into one or more fields if it is desired for them to be ignored for the alarm condition. A 1 Hz and
a 32 kHz clock output are also available.
The DS1306 supports a direct interface to Motorola SPI serial data ports or standard 3-wire interface. An
easy-to-use address and data format is implemented in which data transfers can occur 1 byte at a time or
in multiple-byte burst mode.
OPERATION
The block diagram in Figure 1 shows the main elements of the Serial Alarm RTC.
