DS1672 Description

The DS1672 incorporates a 32-bit counter and power-monitoring functions. The 32-bit counter is designed to count seconds and can be used to derive time-of-day, week, month, and year by using a software algorithm. A precision, temperature-compensated reference and comparator circuit monitors the status of Vcc. When an out-of-tolerance condition occurs, an internal power-fail signal is generated that forces the reset to the active state. When Vcc returns to an in-tolerance condition, the reset signal is kept in the active state for a period of time to allow the power supply and processor to stabilize.

The DS1672 provides a 32-bit counter that increments once-per-second. The counter data is accessible via an I²C serial interface. A precision, temperature-compensated, voltage reference and comparator circuit monitors Vcc. The DS1672 operates as a slave device on the I²C bus. Access is obtained by implementing a START condition and providing a device identification code followed by a register address. Subsequent registers can be accessed sequentially until a STOP condition is executed.

This article provides you with a basic overview of the DS1672 Binary Counter RTC, including its pin descriptions, features and specifications, etc., to help you quickly understand what DS1672 is.

  • Type
    Binary Counter
  • Voltage - Supply

    Voltage - Supply refers to the range of voltage levels that an electronic component or circuit is designed to operate with. It indicates the minimum and maximum supply voltage that can be applied for the device to function properly. Providing supply voltages outside this range can lead to malfunction, damage, or reduced performance. This parameter is critical for ensuring compatibility between different components in a circuit.

    2.7V~3.3V
  • Base Part Number

    The "Base Part Number" (BPN) in electronic components serves a similar purpose to the "Base Product Number." It refers to the primary identifier for a component that captures the essential characteristics shared by a group of similar components. The BPN provides a fundamental way to reference a family or series of components without specifying all the variations and specific details.

  • Interface

    In electronic components, the term "Interface" refers to the point at which two different systems, devices, or components connect and interact with each other. It can involve physical connections such as ports, connectors, or cables, as well as communication protocols and standards that facilitate the exchange of data or signals between the connected entities. The interface serves as a bridge that enables seamless communication and interoperability between different parts of a system or between different systems altogether. Designing a reliable and efficient interface is crucial in ensuring proper functionality and performance of electronic components and systems.

  • Date Format

    The international standard recommends writing the date as year, then month, then the day:?YYYY-MM-DD.

    Binary
  • Current - Timekeeping (Max)

    The parameter "Current - Timekeeping (Max)" in electronic components refers to the maximum current that a device can draw while performing timekeeping functions. Timekeeping functions typically involve maintaining accurate time and date information within a device, such as in a real-time clock (RTC) or a microcontroller with a built-in clock. The maximum current specified for timekeeping is important for determining the power consumption of the device when it is in standby or low-power modes, as excessive current draw can drain the battery quickly. Designers need to consider this parameter when selecting components for battery-powered devices to ensure efficient power management and longer battery life.

  • Voltage - Supply, Battery

    Voltage - Supply, Battery refers to the nominal voltage level provided by a battery to power electronic components or circuits. It indicates the standard voltage output that a battery can deliver under typical operating conditions. This parameter is crucial for ensuring compatibility between the battery and the electronic device, as it affects performance and functionality. The voltage supply rating helps in selecting the appropriate battery for specific applications, ensuring that the device operates efficiently and safely.

    1.3V~3.63V
  • Features

    In the context of electronic components, the term "Features" typically refers to the specific characteristics or functionalities that a particular component offers. These features can vary depending on the type of component and its intended use. For example, a microcontroller may have features such as built-in memory, analog-to-digital converters, and communication interfaces like UART or SPI.When evaluating electronic components, understanding their features is crucial in determining whether they meet the requirements of a particular project or application. Engineers and designers often look at features such as operating voltage, speed, power consumption, and communication protocols to ensure compatibility and optimal performance.In summary, the "Features" parameter in electronic components describes the unique attributes and capabilities that differentiate one component from another, helping users make informed decisions when selecting components for their electronic designs.

    RoHS means “Restriction of Certain Hazardous Substances” in the “Hazardous Substances Directive” in electrical and electronic equipment.

    ROHS3 Compliant
  • Lead Free

    Lead Free is a term used to describe electronic components that do not contain lead as part of their composition. Lead is a toxic material that can have harmful effects on human health and the environment, so the electronics industry has been moving towards lead-free components to reduce these risks. Lead-free components are typically made using alternative materials such as silver, copper, and tin. Manufacturers must comply with regulations such as the Restriction of Hazardous Substances (RoHS) directive to ensure that their products are lead-free and environmentally friendly.
