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. The GL824/GL824C had USB 2.0 Multi-I/F and SD/MMC/MS/MSPro Interface Flash Card Reader Controller. It supports USB 2.0 high-speed transmission to: CompactFlash TM(CF) Type I/II, Micro Drive, Secure Digital^TM (SD), Mini SD^TM, MultiMediaCard^TM (MMC), RS MultiMediaCard^TM (RS MMC), HS-MMC, MMC-Mobile, Memory Stick^TM (MS), Memory Stick Duo^TM (MS Duo), High Speed Memory Stick^TM (HS MS), Memory Stick Pro^TM (MS Pro), Memory Stick Pro^TM Duo(MS Pro Duo) Memory Stick ROM, SmartMedia^TM (SM) 5V/3.3V, and xD-Picture Card^TM (xD) on one chip (GL824C are SD/MMC/MS/MSPro I/F only). The GL824/GL824C also embeds a powerful 8-bit MCU engine to handle the operations among the USB host, peripheral, OTG and ATA/ATAPI controllers. Provide flexibility Card-to-HDD, HDD-to-Card, USB-to-HDD, HDD-to-USB, USB-to-Card and Card-to-USB multi-path copy back bridge.
