Overview of ST-LINK/V2

The ST-LINK/V2 is an in-circuit debugger and programmer for the STM8 and STM32 microcontrollers. The single-wire interface module (SWIM) and JTAG/serial wire debugging (SWD) interfaces are used to communicate with any STM8 or STM32 microcontroller located on an application board. In addition to providing the same functionalities as the ST-LINK/V2, the ST-LINK/V2-ISOL features digital isolation between the PC and the target application board. It also withstands voltages of up to 1000 Vrms.

  • 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.

    USB
  • Data Bus Width

    The data bus width in electronic components refers to the number of bits that can be transferred simultaneously between the processor and memory. It determines the amount of data that can be processed and transferred in a single operation. A wider data bus allows for faster data transfer speeds and improved overall performance of the electronic device. Common data bus widths include 8-bit, 16-bit, 32-bit, and 64-bit, with higher numbers indicating a larger capacity for data transfer. The data bus width is an important specification to consider when evaluating the speed and efficiency of a computer system or other electronic device.

  • Evaluation Kit

    An Evaluation Kit is a collection of hardware and software components designed to help engineers and developers assess and test the functionality of a particular electronic component or system. It typically includes a development board, sample code, utilities, and documentation to facilitate development and prototype testing. Evaluation Kits enable users to quickly prototype applications, evaluate performance characteristics, and determine compatibility with other systems. They are commonly used in the design and development phases of electronic projects to simplify the integration of complex components.

    Yes
  • Core Architecture

    In electronic components, the term "Core Architecture" refers to the fundamental design and structure of the component's internal circuitry. It encompasses the arrangement of key components, such as processors, memory units, and input/output interfaces, within the device. The core architecture plays a crucial role in determining the component's performance, power efficiency, and overall capabilities. Different core architectures are optimized for specific applications and requirements, such as high-speed processing, low power consumption, or specialized functions. Understanding the core architecture of electronic components is essential for engineers and designers to select the most suitable components for their projects.

  • REACH SVHC

    The parameter "REACH SVHC" in electronic components refers to the compliance with the Registration, Evaluation, Authorization, and Restriction of Chemicals (REACH) regulation regarding Substances of Very High Concern (SVHC). SVHCs are substances that may have serious effects on human health or the environment, and their use is regulated under REACH to ensure their safe handling and minimize their impact.Manufacturers of electronic components need to declare if their products contain any SVHCs above a certain threshold concentration and provide information on the safe use of these substances. This information allows customers to make informed decisions about the potential risks associated with using the components and take appropriate measures to mitigate any hazards.Ensuring compliance with REACH SVHC requirements is essential for electronics manufacturers to meet regulatory standards, protect human health and the environment, and maintain transparency in their supply chain. It also demonstrates a commitment to sustainability and responsible manufacturing practices in the electronics industry.

    No SVHC
  • Radiation Hardening

    Radiation hardening is the process of making electronic components and circuits resistant to damage or malfunction caused by high levels of ionizing radiation, especially for environments in outer space (especially beyond the low Earth orbit), around nuclear reactors and particle accelerators, or during nuclear accidents or nuclear warfare.

    No
  • RoHS Status

    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.
