DS1307 DS1307 64 x 8, Serial, I2C Real-Time Clock GENERAL DESCRIPTION FEATURES The DS1307 serial real-time clock (RTC) is a lowpower, full binary-coded decimal (BCD) clock/calendar plus 56 bytes of NV SRAM. Address and data are 2 transferred serially through an I C, bidirectional bus. 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 12hour format with AM/PM indicator. The DS1307 has a built-in power-sense circuit that detects power failures and automatically switches to the backup supply. Timekeeping operation continues while the part operates from the backup supply.          Real-Time Clock (RTC) Counts Seconds, Minutes, Hours, Date of the Month, Month, Day of the week, and Year with Leap-Year Compensation Valid Up to 2100 56-Byte, Battery-Backed, General-Purpose RAM with Unlimited Writes 2 I C Serial Interface Programmable Square-Wave Output Signal Automatic Power-Fail Detect and Switch Circuitry Consumes Less than 500nA in Battery-Backup Mode with Oscillator Running Optional Industrial Temperature Range: -40°C to +85°C Available in 8-Pin Plastic DIP or SO Underwriters Laboratories (UL) Recognized TYPICAL OPERATING CIRCUIT VCC PIN CONFIGURATIONS VCC TOP VIEW CRYSTAL VCC RPU VCC X1 RPU SQW/OUT X2 VBAT X1 SCL X2 VCC GND VCC SQW/OUT X2 SCL VBAT SDA GND SCL SDA SQW/OUT SO (150 mils) CPU X1 PDIP (300 mils) DS1307 SDA GND VBAT RPU = tr/Cb ORDERING INFORMATION PART DS1307+ DS1307N+ DS1307Z+ DS1307ZN+ DS1307Z+T&R DS1307ZN+T&R TEMP RANGE VOLTAGE (V) 0°C to +70°C -40°C to +85°C 0°C to +70°C -40°C to +85°C 0°C to +70°C -40°C to +85°C 5.0 5.0 5.0 5.0 5.0 5.0 PIN-PACKAGE TOP MARK* 8 PDIP (300 mils) 8 PDIP (300 mils) 8 SO (150 mils) 8 SO (150 mils) 8 SO (150 mils) Tape and Reel 8 SO (150 mils) Tape and Reel DS1307 DS1307N DS1307 DS1307N DS1307 DS1307N +Denotes a lead-free/RoHS-compliant package. *A “+” anywhere on the top mark indicates a lead-free package.
