The DS1747WP-120 is an Integrated Circuit (IC) component primarily used in electronic systems and devices that require non-volatile timekeeping and data storage. It is a combination of a real-time clock (RTC) and a static random-access memory (SRAM), allowing it to provide accurate timekeeping along with data storage functionalities. Below are the key features and an overview of the DS1747WP-120 IC component:
1. Real-Time Clock:
- The DS1747WP-120 includes a built-in real-time clock that provides precise timekeeping information.
- It has a dedicated 32-bit counter that increments every second, supported by an on-board crystal oscillator for accurate timekeeping.
- The clock supports hours, minutes, and seconds, along with day, date, month, and year values.
2. Non-Volatile SRAM:
- The IC integrates a non-volatile SRAM, which retains data even during power loss or system shutdown.
- The non-volatile nature of the SRAM eliminates the need for battery-backed systems to store critical data.
- It has a storage capacity of 32 kilobytes (32K) and operates on a 120ns access time.
3. Battery Backup:
- The DS1747WP-120 utilizes an external battery backup to retain data during power interruptions.
- The battery supply ensures that the RTC keeps running and that the SRAM retains data when the main power source is disconnected
