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 SOP Underwriters Laboratories (UL) Recognized ORDERING INFORMATION Package Type MARKING Packing Packing Qty DS1307N DEVICE DIP8L DS1307 TUBE 2000/box DS1307M/TR SOP8L DS1307 REEL 2500/reel DS1307ZN DIP8L DS1307Z TUBE 2000/box DS1307ZM/TR SOP8L DS1307Z REEL 2500/reel TYPICAL OPERATING CIRCUIT PIN CONFIGURATIONS VCC TOP VIEW VCC VCC RPU VCC X1 CRYSTAL RPU SQW/OUT X2 VBAT X1 SCL CPU X2 VCC GND SQW/OUT SOP8 X1 VCC SQW/OUT X2 SCL VBAT SDA GND SCL SDA DIP8 DS1307 SDA GND VBAT RPU = tr/Cb http://www.hgsemi.com.cn 1 2018 MAY V1.0  PDF
