DS1248W-120IND+

The DS1248W-120IND+ is a real-time clock (RTC) module available from Dallas Semiconductor/Maxim Integrated, designed for today’s always-connected computing environment. It integrates several important functional components: a real-time clock (RTC), an alarm, a battery-backed memory, a watchdog timer (WDT), a power supply, a temperature sensor, and oscillator circuitry, into one package. The DS1248W-120IND+is engineered to be compact, low-power, and highly reliable. It allows users to easily add time-stamping capability to applications in a variety of systems.

Real-time clocks are essential components of systems that require accurate timekeeping, such as power-sensitive devices, such as smartphones and tablet computers, medical equipment, industrial controls, automotive applications, and embedded systems. A real-time clock represents the system’s clock and provides an accurate time reference from which other system components can synchronize their operation. The DS1248W-120IND+ is an excellent choice for applications that require a low-power and precise timekeeping system.

The DS1248W-120IND+ is designed to fit into a variety of applications and offers a wide range of features. It is designed to be low-power, with a maximum supply current of only 80 microamps. It integrates two independent real-time clock and alarm counters, two digital thermometer channels, a battery-backed RAM, and an integrated watchdog timer. The timekeeping accuracy of the RTC is ±2.5 ppm at full operation, making it an excellent choice for low-power, precise timekeeping applications. It also offers an integrated temperature sensor, which is often useful in applications such as temperature logging and control. Additionally, it has an integrated power supply, which makes it easy to connect to a variety of voltage sources and minimizes the need for external components.

The DS1248W-120IND+ also includes a highly reliable watchdog timer (WDT). The WDT can be programmed to reset the system if it fails to receive notification from the host processor within a certain period of time. This is useful for applications that require reliable monitoring, such as medical and industrial systems. Additionally, the device has a wide operating temperature range from -40°C to 85°C, making it ideal for applications in extreme environments.

The DS1248W-120IND+ is a low-power and reliable RTC that can easily add time-stamping capability to a variety of applications. Its features make it an ideal choice for applications that require precise timekeeping and reliable monitoring. Additionally, its integrated power supply and temperature sensor increase system design flexibility and expand the range of applications that can benefit from its use.
