Microchip USB Bridges

USB Bridges

Our USB bridge controllers provide an ultra-fast interface between a USB host and popular Flash media card formats, UART, SPI and Smart Card interfaces. These low-pin count, configurable and turnkey bridges are simple to implement and cost effective to deploy. They also can be used in conjunction with our Hi-Speed Inter-Chip (HSIC)-based USB 2.0 hub controllers for applications that demand low power consumption, a small device size and a cost-reduced BOM without compromising on performance or features. Ideal for enabling card reader functionality in low-power embedded applications, these small-footprint ICs can be used in many different applications including multi-function printers, set-top boxes, automobile audio systems, user authentication and point-of-sale terminals.
