This Real Time Clock (RTC) is a low-power, full Binary-Coded Decimal (BCD) clock/calendar that also features 56 bytes of non-volatile SRAM. Data communication is handled by a bidirectional I²C serial interface. The data supplied by the clock function includes seconds, minutes, hours, day, date, month and year. The device also has automatic month-end adjustments for non-31 day months and for leap years. The clock will operate in 12- or 24-hour format and has an AM/PM indicator. This RTC has built-in power-sense circuitry that detects power failures and automatically switches to a backup supply, keeping timekeeping functions active. * 0°C to +70°C Commercial temperature range * Surface mounting SO-8 package * 56 byte Battery-backed NV SRAM for data storage * I²C Serial interface * Programmable square-wave output signal * Automatic power-fail detect and switchover circuitry * Consumes <500nA in battery-backup mode with oscillator running https://elecena.pl/product/27213641/maxim-ds1307z-linear-ic-soic8-real-time-clock 2024-11-10 https://elecena.pl/product/27213641/maxim-ds1307z-linear-ic-soic8-real-time-clock 2025-03-22 https://elecena.pl/product/27213641/maxim-ds1307z-linear-ic-soic8-real-time-clock 2025-05-20 https://elecena.pl/product/27213641/maxim-ds1307z-linear-ic-soic8-real-time-clock 2025-06-27 https://elecena.pl/product/27213641/maxim-ds1307z-linear-ic-soic8-real-time-clock 2025-07-17 https://elecena.pl/product/27213641/maxim-ds1307z-linear-ic-soic8-real-time-clock 2025-08-26 https://elecena.pl/product/27213641/maxim-ds1307z-linear-ic-soic8-real-time-clock 2026-06-14 https://elecena.pl/product/27213641/maxim-ds1307z-linear-ic-soic8-real-time-clock 2026-07-08 https://elecena.pl/product/27213641/maxim-ds1307z-linear-ic-soic8-real-time-clock 2026-08-23
