The DS1746W-120+ is an integrated circuit (IC) component that belongs to the DS1746 series of timekeeping RAM. This component is manufactured by Maxim Integrated Products, a renowned semiconductor company. It combines a real-time clock (RTC) with battery-backed SRAM in a single package, providing accurate timekeeping and non-volatile memory functionality.
Key features of the DS1746W-120+ include:
1. Real-Time Clock (RTC): The built-in RTC accurately tracks the current time and date, including leap years. It operates in a 12-hour or 24-hour format and provides programmable alarms.
2. Battery-Backed SRAM: The DS1746W-120+ integrates non-volatile SRAM, which retains data in case of power loss. This feature is especially useful for applications requiring data persistence.
3. I2C Interface: The IC communicates through an I2C interface, enabling easy integration with microcontrollers, processors, or other peripheral devices. The interface supports two-wire communication at various speeds.
4. Extensive Operating Temperature Range: The DS1746W-120+ operates reliably in rugged environments, with an extended temperature range of -40°C to +85°C. This allows it to be used in a wide range of industrial and automotive applications.
5. Low Power Consumption: The component is designed to minimize power consumption, enabling efficient operation in battery-powered devices
