The DS12885QN+ is a real-time clock (RTC) integrated circuit (IC) component developed by Maxim Integrated. It is a high-precision and low-power module designed to keep track of time and date in various electronic systems. Here is an overview of the key features offered by this IC component:
1. Real-Time Clock: The DS12885QN+ includes a built-in real-time clock that provides highly accurate timekeeping capabilities. It uses a 32.768 kHz quartz crystal oscillator, ensuring precise time measurement.
2. Non-Volatile RAM: This IC component incorporates 114 bytes of non-volatile RAM (NV SRAM), which can be used to store critical data even when the power supply is disconnected. This feature is particularly useful in applications where data retention is crucial.
3. BCD Timekeeping: The DS12885QN+ represents time and date information in Binary-Coded Decimal (BCD) format. It supports hours, minutes, seconds, days, months, and years in BCD encoding, enabling easy integration into various systems.
4. Alarm and Interrupt Functions: The IC component includes two programmable time-of-day alarms, which can be configured to trigger an interrupt or square wave output. This functionality allows the device to provide alert notifications according to a predefined schedule.
5. Unique Serial Number: Each DS12885QN+ IC module has a globally unique 48-bit serial number programmed at the factory
