Fresco Logic FL1100 is a USB 3.0 host controller chip. It is designed to provide high-speed USB connectivity to desktop computers and laptops that lack built-in USB 3.0 support. USB 3.0, also known as SuperSpeed USB, offers significantly faster data transfer rates compared to its predecessor, USB 2.0.
The FL1100 chip is used in various expansion cards and motherboards to upgrade existing systems to support USB 3.0 peripherals, such as external hard drives, flash drives, and other devices. It is backward compatible with USB 2.0 and USB 1.1 devices, allowing users to connect both old and new USB peripherals.
