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

(CF), Micro Drive, SmartMedia

(SM), Secure Digital

(SD), Multi Media Card

(MMC), and MemoryStick

(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.
