Micro, and xD-Picture Card (xD) on one chip. As a single chip solution for USB 2.0 flash card reader, the
GL827S complies with Universal Serial Bus specification rev. 2.0, USB Storage Class specification ver.1.0, and
flash card interface specification each.
The GL827S can support different kinds of interfaces in single slot and integrates a high speed 8051
microprocessor and a high efficiency hardware engine for the best data transfer performance between USB
and flash card interfaces.
The GL827S pin assignment design fits to card sockets to provide easier PCB layout. 48 Pin LQFP (7mm x
7mm) , QFN28 (5mm x 5mm) and QFN24 (4mm x 4mm) are available package types.
