The DS1744-70IND+ is an integrated circuit (IC) component developed by Maxim Integrated. It is a part of the DS1744 family of timekeeping solutions and offers several key features. Let's delve into its overview and significant characteristics.
The DS1744-70IND+ is a real-time clock (RTC) IC with an integrated non-volatile static RAM (NVSRAM). This device operates by combining a high-precision oscillator, calendar functionality, and a small amount of non-volatile memory on a single chip.
One of the notable features of the DS1744-70IND+ is its ability to provide extremely accurate timekeeping, with ±2 minutes per year typical accuracy. This precision makes it suitable for applications that require accurate time-stamping, event scheduling, and data logging.
The IC incorporates a 4-bit parallel interface, allowing easy integration with various microcontrollers or processors. Its non-volatile RAM offers 16 kilobits (2 kilobytes) of storage capacity and is organized as 16 separate 128-bit pages, enabling flexible data storage and retrieval.
The DS1744-70IND+ also supports battery backup, ensuring that the clock and critical data remain operational even during power loss or system shutdowns. It utilizes a lithium coin-cell battery to maintain time and memory functionality, offering long-term reliability and low power consumption.
Furthermore, this IC component incorporates a programmable watchdog timer, which allows the users to monitor system activity
