1. Description
The MA8168A is a new generation high performance USB 2.0 multiple slots single Lun (Logical Unit
Number) card reader which supports multiple cards which includes most updated Secure Digital Card (SD3.0),
MultiMedia Card, xD-Picture Card, Memory Stick, Memory Stick Pro, Memory Stick PRO-HG Duo, Memory
Stick XC-HG, Compact Flash, Smart Media Card, and Micro Drive. The MA8168A integrates USB 2.0
transceiver, MCU, DC-DC regulators and memory card access unit into a single chip. In order to provide best
performance, MA8168A integrates a high speed 8051 microprocessor and a high efficiency hardware engine
for best data transfer performance between USB and various memory card interfaces.
In order to meet market standard, MA8168A integrates power MOSFET to improve ESD performance,
over current protection design to prevent from short current. For reducing BOM cost, MA8168A reserve
flexibility to remove external 12Mhz Xtal on PCB, which means the clock source is generated from MOAI’s
proprietary on chip clock design.
