GL816 USB 2.0 Flash Card Reader Controller

CHAPTER 1 GENERAL DESCRIPTION

The GL816 is a highly integrated, flexible application USB 2.0 Multi-Interface Flash Card Reader controller.

It supports USB 2.0 high-speed transmission to PCMCIA, CompactFlash TM (CF), Micro Drive,

SmartMediaTM (SM), Secure Digital TM (SD), Multi Media Card TM (MMC), and MemoryStick TM (MS)

interface on one chip. Besides the flash card interface controller each, the GL816 integrates Genesys Logic

own design USB 2.0 high-speed UTMI (USB 2.0 Transceiver Macrocell Interface) transceiver. As a single

chip solution for USB 2.0 multi flash card reader, the GL816 complies with Universal Serial Bus specification

rev. 2.0, USB Storage Class specification ver.1.0, and flash card interface specification each.

The GL816 can support different kinds of multi-interface combinations. For the best performance

consideration, the GL816 integrates high efficiency card interface hardware engine for data transfer, and the

48MHz feature-enhanced 8051 micro-controller. The GL816 also supports firmware upgrade via USB

interface, and external flash read/ write for firmware upgrade and other applications. With the advanced

mobile consideration in the IA application, the GL816 can support Inter-Media transfer, it means that the data

transfer between different cards doesn’t need the support of USB host in PC system.

The GL816 equips dedicated power control pins for different cards and power / busy indication. And the pin

assignment design fits to card sockets to provide easier PCB layout. With 8 additional GPIOs, and firmware

controllable CD, CE pins, the GL816 can be programmed to fit your various design in USB 2.0 high speed

multi-interface flash card reader applications.
