The DS1685E-3+ is an IC (integrated circuit) component developed by Maxim Integrated. It is a real-time clock (RTC) and supervisor chip that offers various features and functionalities. This IC component is designed for use in a wide range of electronic devices that require accurate timekeeping and system monitoring capabilities.
One of the key features of the DS1685E-3+ is its real-time clock. It includes an integrated quartz crystal oscillator that provides precise timekeeping functionality. The RTC continuously tracks the time, date, and day of the week, even in the absence of power supply.
The DS1685E-3+ also incorporates a supervisor function, which monitors the system for voltage levels, power-fail conditions, and low battery situations. It has programmable voltage thresholds that detect power interruption or undervoltage events. When such events occur, the chip can generate a reset signal to the microcontroller, allowing proper system shutdown or preventing data loss.
This IC component is equipped with non-volatile memory (NVRAM) that enables short-term data storage during power interruptions. The DS1685E-3+ offers up to 1,024 bytes of non-volatile SRAM, which can be used to save critical information like system status, user preferences, or sensor data.
Additionally, the DS1685E-3+ integrates a watchdog timer. This feature allows the system to be monitored for software or hardware malfunctions
