Tiny RTC I2C DS1307 real time clock + EEPROM AT24C32 module

Tiny RTC I2C DS1307 real time clock + EEPROM AT24C32 module 2 in 1 module, memiliki IC RTC (Real Time Clock) dan EEPROM AT24C32. Real Time Clock berguna sebagai penghitung jam dan tanggal. Sangat berguna untuk project jam digital. EEPROM AT24C32 adalah EEPROM berkapasitas 32kB. Sangat cocok untuk menyimpan data atau nilai pada saat main system tidak diberi supply power. Menggunakan baterai CR2032 rechargeable. untuk baterai terisi penuh DS1307 tdapat mempertahankan perhitungan waktu sampai 1 tahun. Ukuran : 27mm * 28mm * 8.4mm DS1307 is a low power, with 56 bytes of non-volatile RAM clock calendar full BCD code real-time clock chip, the address and data via a two-wire bidirectional serial bus transmission, the chip provides seconds, minutes, hours and other information , the number of days of each month can be automatically adjusted. And there is a leap year compensation. AM / PM flag determines clock operates in 24 hours or 12 hours mode, the chip has a built-in power-sense circuit, brownout detect, and battery switching function. Available on the second, hour, minute, number of days per month, month, week, count the number of days, and has a leap year compensation. Record on the line in 2100. 56 bytes of non-volatile RAM Two-wire serial interface Programmable square-wave output Automatic power-down detection and switching circuit In battery backup mode, power consumption is less than 500nA
