Maxim Integrated DS1746-70IND

The DS1746-70IND is a robust, high-performance real-time clock (RTC) with a built-in microprocessor monitor from Maxim Integrated. It is specifically designed to cater to the demanding requirements of industrial applications, providing both reliability and precision in timekeeping. The DS1746-70IND combines multiple functions into a single package, including a full-function RTC, an NV SRAM controller, a microprocessor monitor, and a crystal, all encapsulated in a convenient 34-pin PowerCap Module (PCM) package.

One of the key features of the DS1746-70IND is its integrated 64KB of NV SRAM, which offers nonvolatile data retention without the need for an external battery. This is particularly useful for preserving critical data during power loss events. The device ensures that all data is maintained intact and readily available upon power restoration, a crucial factor for mission-critical systems.

The RTC component of the DS1746-70IND is designed to maintain accurate time and date information, ranging from seconds to years, including leap year compensation up to the year 2100. It is ideal for applications that require precise timekeeping, such as data logging systems, industrial machines, and other time-sensitive devices.

Additionally, the DS1746-70IND features a microprocessor monitor which offers watchdog and power-on reset functions. These functions are essential for ensuring system stability and reliability by monitoring system operation and initiating a reset in case of a malfunction or erratic behavior.

The device operates over an industrial temperature range of -40°C to +85°C, making it suitable for harsh environments where standard RTCs might fail. Its robustness and durability are further emphasized by its PowerCap Module packaging, which is designed to withstand the rigors of industrial use.

The DS1746-70IND is a versatile and essential component for systems that cannot afford downtime and require accurate timekeeping and data integrity at all times. With its combination of RTC, NV SRAM, and system monitoring capabilities, it represents a comprehensive solution for a wide range of industrial applications.
