GL3466

USB 3.2 Gen1 Stand-Alone Scanner Controller
Genesys Logic’s single-chip GL3466 is a high speed, high performance, and rich scalability controller for standalone scanner. It is designed for bus-powered, portable or fast sheet-fed scanner controller. It successfully integrates ARM11 CPU, scanner function ASIC, JPEG encoder/decoder, USB 3.2 Gen1 device and USB 2.0 EHCI hosts controller into one single-chip. With its high performance design architecture, GL3466 is ready for supporting CIS or CCD image sensors (600~9600dpi resolution) that are used in ADF sheet-fed and DC motor scanner.
