The DS12C887+ is a real-time clock (RTC) integrated circuit (IC) component designed by Maxim Integrated. It offers accurate timekeeping and various additional features for use in electronic systems.
Key Features of the DS12C887+ include:
1. Real-Time Clock: The DS12C887+ provides accurate time and date information in seconds, minutes, hours, days, months, and years. It supports both the 12-hour and 24-hour formats.
2. Battery Backup: This IC has a built-in battery backup system that allows it to maintain accurate time and date even during power outages. It supports a lithium coin cell battery for backup power supply.
3. Non-Volatile RAM: The DS12C887+ features 114 bytes of battery-backed non-volatile RAM (NVRAM). This memory can be used to store system data, critical settings, and information that needs preservation during power loss.
4. Alarm Functionality: It includes an alarm with a programmable frequency and a dedicated alarm output pin. This feature enables the IC to generate interrupts or provide a signal when a specific time or condition is reached.
5. Square Wave Generator: The DS12C887+ can generate periodic square wave signals with selectable frequencies, facilitating applications that require frequency generation or timekeeping signals.
6. Programmable Components: It provides various programmable counters and timers for customization based on specific application requirements
