CYUSB3326-BVXC

Embedded - Microcontrollers - Application Specific

The CYUSB3326-BVXC is an advanced software-programmable USB-seamless bridge microcontroller, which is intended to bridge traffic between existing USB 2.0-compliant peripheral devices and the newer USB 3.0-compliant previous devices or other USB 2.0-compliant peripheral devices. It is equipped with several features and provides a range of mixed-mode USB 2.0 and USB 3.0 interfaces, making it a convenient solution for those looking to bridge between old and new. Additionally, basic knowledge of embedded microcontroller programming, such as C and assembly, are beneficial for implementing this product.

CYUSB3326-BVXC is suitable for a variety of USB 3.0 applications. It is commonly used for providing an upgrade path for older USB 2.0 peripheral devices, by allowing them to be connected to newer USB 3.0 hosts. Other applications include bridging between a USB 3.0 host controller and a USB 2.0 device, or between two USB 2.0 devices; in this case it functions as a USB 2.0 bridge. It is also useful for transferring data between two different USB buses, as well as providing a modified VID and PID list to enable the connection of USB 3.0 devices to a USB 2.0 host.

CYUSB3326-BVXC offers several features which make it a versatile device. This includes flexible I/O routing, which allows the user to assign up to four arbitrary I/Os to any of the four available USB-seamless interface pins. Additionally, it supports power switching, where it enables the user to match the power requirements of the device to the target host\'s capability. It is also equipped with a very powerful feature called Multi-Port Virtualization, which allows the user to consolidate multiple USB peripherals into a single virtual device for aggregated bandwidth and efficient device management, such as multiple endpoints, multiple interfaces and multiple device classifications.

CYUSB3326-BVXC also provides scalability and flexibility, as any number of resources such as RAM and FPGA are shareable across multiple USB ports, enabling the user to extend the capabilities of the device, further eliminating the need for additional components or external controllers. Additionally, it supports multiple channels and simultaneous USB operations, allowing for the expansion of USB tasks over different ports.

In terms of working principle, CYUSB3326-BVXC operates in either write or read mode. In write mode, the interface is integrated into the peripheral, and data transmission is initiated from the peripheral to the host. In read mode, the interface is integrated into the host, and data transmission is initiated from the host to the peripheral. The user must configure the interface to both the peripheral and the host before data transmission can take place. In addition, the user is responsible for implementing the appropriate signal lines for transfers of data between the host and the peripheral.

CYUSB3326-BVXC provides an effective and convenient solution for bridging between USB 2.0 and USB 3.0 hosts and peripherals. It features several features that make it an ideal device for a wide range of application-specific scenarios. Additionally, its scalability and flexibility make it a great choice for those looking to expand their USB capabilities quickly and efficiently.
