The ASMedia ASM3142 is a USB 3.1 Gen 2 (also known as USB 3.2 Gen 2) controller chip manufactured by ASMedia Technology Inc., a Taiwanese fabless semiconductor company. The ASM3142 is commonly used in motherboards and expansion cards to provide high-speed USB connectivity for various devices.
USB 3.1 Gen 2 is the second iteration of USB 3.1 and offers significantly faster data transfer rates compared to its predecessors. The ASM3142 controller is designed to fully support the USB 3.1 Gen 2 standard, providing a maximum data transfer rate of up to 10 Gbps (gigabits per second). This increased bandwidth allows for faster data transfer and improved performance for compatible devices like external storage drives, high-resolution cameras, and other peripherals.
The ASM3142 chip is backward compatible with previous USB standards, such as USB 3.1 Gen 1 (USB 3.0) and USB 2.0. This means it can also handle devices using older USB specifications at their respective speeds.
ASMedia has been a well-known supplier of USB controller chips, and their ASM3142 chip has been widely adopted by various motherboard manufacturers and hardware developers. The popularity of USB 3.1 Gen 2 and the ASM3142 controller has further driven the adoption of high-speed USB connectivity in modern computer systems, enhancing data transfer capabilities and supporting the needs of fast-paced computing and data-intensive applications.
