The DS1344D-33+T&R is a Low current SPI/3-wire RTC in 14 pin TDFN package. This time keeping device provides an extremely low standby current permitting longer life from backup supply source. It also supports high ESR crystals, broadening pool of usable crystals for devices. The clock/calendar provides seconds, minutes, hours, day, date, month & year information. The date at end of month is automatically adjusted for months with fewer than 31 days, including corrections for leap year. The clock operates in either 24hr or 12hr format with an AM(complementary)/PM indicator. Address & data are transferred serially through an SPI or 3-wire interface. Two programmable time of day alarms are provided. Each alarm can generate an interrupt on 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.

• Supply voltage range is 3V to 5.5V
• Operating temperature range from -40°C to 85°C
• Interrupt outputs operate when device is powered by either VCC or VBAT
• Low timekeeping current of 350nA, power-fail & switch circuitry
• Compatible with crystal ESR up to 100Kohm, trickle-charge capability
• Versions available to support either 12.5pF crystals
• Burst mode for reading/writing successive addresses in clock/RAM
• 96byte battery-backed NV RAM for data storage
• UL recognized
• Support Motorola SPI modes 1 and 3 or standard 3-wire interface
