DS1747-70

The DS1747-70 is an Integrated Circuit (IC) component that serves as a real-time clock/calendar with non-volatile (NV) RAM. It is part of the DS17xx family of ICs developed by Maxim Integrated. This component offers reliable timekeeping and data storage capabilities to various electronic devices. Below are the key features and an overview of the DS1747-70: 1. Real-Time Clock (RTC): The DS1747-70 provides accurate timekeeping with a dedicated oscillator, which ensures precise timing across a wide temperature range. It maintains accurate time even during power interruptions or when the main power supply is disconnected. 2. Non-volatile RAM: This IC integrates non-volatile static RAM (NV SRAM), which allows the retention of data even without a continuous power supply. The NV SRAM provides byte-level random access, making it ideal for storing critical data and system parameters. 3. Battery Backup: The DS1747-70 includes a battery backup input that enables the use of an external lithium coin cell, ensuring that the clock and SRAM are powered even when the primary power source is unavailable. This ensures uninterrupted operation and data storage. 4. Trickle Charge Functionality: In order to maintain the external battery's charge level, this IC incorporates a trickle-charge capability. This feature ensures the long-term viability of the backup power source
