The DS1305E+T&R is an integrated circuit (IC) component developed by Maxim Integrated. It is mainly used as a real-time clock (RTC) and calendar, providing accurate timekeeping functions for various electronic devices. This IC is packaged in a small, surface-mount 8-pin TSSOP package and operates with a wide supply voltage range from 2.7V to 5.5V.
Key Features of the DS1305E+T&R:
1. Real-time Clock: The DS1305E+T&R offers a real-time clock feature, which accurately keeps track of hours, minutes, and seconds. It also provides a calendar that includes the day, date, month, and year.
2. Battery Backup: This IC incorporates a battery backup circuitry that allows it to retain timekeeping data even in the absence of the main power supply. This ensures uninterrupted timekeeping during power outages.
3. Trickle Charger: The DS1305E+T&R includes a trickle charger circuit, which charges an external capacitor to back up the power supply in the absence of the main power source. This feature ensures reliable operation during power interruptions.
4. Programmable Alarms: It offers two programmable alarms that can be set to trigger at specific times, acting as reminders or activating other system functions. Each alarm can be individually configured for the desired time and day
