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.

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.
SHARC
Boundary Scan
Boundary scan is a testing technique used in electronic components to verify the interconnections between integrated circuits on a printed circuit board. It allows for the testing of digital circuits by providing a way to shift data in and out of devices through a serial interface. This method helps in identifying faults such as short circuits, open circuits, and incorrect connections without the need for physical access to the individual components. Boundary scan is commonly used during manufacturing, testing, and debugging processes to ensure the quality and reliability of electronic products.
YES
Low Power Mode
Low Power Mode is a feature found in electronic components, such as microcontrollers, processors, and devices, that allows them to operate at reduced power consumption levels. When activated, the component typically reduces its clock speed, voltage, or disables certain functions to conserve energy. This mode is often used to extend battery life in portable devices or reduce overall power consumption in energy-efficient systems. Low Power Mode can be triggered automatically based on certain conditions, such as low battery levels, or manually by the user or software. It is a crucial feature in modern electronics to balance performance with energy efficiency.
NO
Integrated Cache
Integrated Cache refers to a type of memory storage that is built directly into a microprocessor or other electronic component. It is used to temporarily store frequently accessed data and instructions to speed up processing and reduce latency. The integrated cache is designed to provide quick access to data that the processor needs to perform its tasks efficiently. By storing data closer to the processor, the integrated cache helps improve overall system performance by reducing the time it takes to retrieve information from the main memory. The size and speed of the integrated cache can have a significant impact on the performance of the electronic component, making it an important parameter to consider when evaluating the capabilities of a device.
YES
Voltage - I/O
Voltage - I/O is a parameter that refers to the voltage levels at the input and output pins of an electronic component, such as an integrated circuit or a semiconductor device. It specifies the range of voltages that the component can accept at its input pins and the voltages it will output at its output pins under normal operating conditions. This parameter is crucial for ensuring proper functionality and compatibility with other components in a circuit. It helps designers determine the appropriate voltage levels to use when interfacing with the component to prevent damage and ensure reliable operation.

Non-Volatile Memory
Non-Volatile Memory refers to a type of storage technology that retains data even when power is turned off. It is essential for preserving important information in electronic devices, such as computers and smartphones. Common examples of non-volatile memory include Flash memory, EEPROM, and ROM. This characteristic makes non-volatile memory crucial for applications where data integrity and retention are required without a continuous power supply.
External
Voltage - Core
Voltage - Core is a parameter that refers to the voltage required to power the core of an electronic component, such as a microprocessor or a graphics processing unit (GPU). The core voltage is essential for the proper functioning of the component, as it provides the necessary power for the core to perform its operations. The voltage level is typically specified by the manufacturer and must be within a certain range to ensure the component operates reliably and efficiently. Monitoring and controlling the core voltage is crucial in maintaining the stability and performance of the electronic component.
1.10V
On Chip Data RAM
On Chip Data RAM refers to a type of memory that is integrated directly onto a microprocessor or other integrated circuit. This RAM is used for storing data temporarily while the device is in operation, allowing for quick access and retrieval of information. On Chip Data RAM is typically faster than external memory due to its proximity to the processor, which helps improve overall system performance. It is commonly used in various electronic components such as microcontrollers, CPUs, and DSPs to facilitate efficient data processing and manipulation.

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.
