GENERAL DESCRIPTION

The GL824/824C USB On-The-Go (OTG) Dual-Role-Device controller which include Milti-I/F and ATA/ATAPI interface is a highly integral microprocessor, which optimized and specially designed for embedded system, portable device, multi-function peripheral and consumer products with External uP interface, SSI, I2C and Flash cards interface.Using the GL824, developers can create OTG-compliant dual-role products capable of point-to-point communication. Its focus on power efficiency makes the GL824 ideal for set top box, DVD player, PDA, PMP, Digital TV and home entertainment with USB OTG and Flash card reader.
