INTRODUCTION:
SD1307 is a low power, full BCD clock with 56 bytes of non-volatile RAM Calendar, factclock chip, address and data transmission through two-line bidirectional serial bus, core thefilm can provide information such as seconds, minutes, and hours. The number of days in eachmonth can be automatically adjusted. Leap year compensation function, AM/AM logo hugeeast clock work with 24 or 12 hour mode, The chip has a built-in current sensing circuit, with power-down detection and battery switching functions.
– DS130712C real-time clock chip(RTC)
– 4C32 32K 12C EEPROM memory
– LIR2032 lithium battery with charging circuit. Solve the problem that DS1307 can’t read and write with backup battery. It can provide DS1307 with timing for 1 year.
– Compact design, 27mm * 28mm * 7mm
– Lead out the clock pin of DS1307 to provide the clock signal for the micro controller. Can cascade other i2C equipment
