• Manufacturer: AMECO

1 INTRODUCTION
The MW6208 is a USB 2.0 high-speed Flash Drive controller. The USB 2.0 high-speed interface
including PHY and function supports USB 2.0 Mass Storage Device Class.
The Mass Storage Controller Interface combined with the Reed-Solomon Encoder/Decoder
on-the- fly correction (5-byte on 528-byte data blocks) provides a flexible, high transfer rate
solution for interfacing a wide of range Flash memory device types. The internal 60 MHz PLL
driven by the 12MHz Oscillator is used to generate the 480MHz frequency for the USB 2.0
PHY.
The Integrated 80C51 MCU runs the application program from the internal ROM and RAM.
USB data and patch code are stored in internal RAM.
I/O ports provide functions for EEPROM, LED and write protect switch control. The internal
5.0V to 3.3V and 3.3V to 1.8V voltage regulator provides the 3.3V and 1.8V supply voltage to

the digital part of the circuit.
MW6208 has optimized internal structure and techniques designed special for MLC
process. With dual-channel and up to 5bytes ECC support, make MLC present excellence
performance as SLC NAND Flash.
MW6208 supports all the FLASH on the today’s market. Include normal SLC/MLC
NAND flash, AND/AG-AND and Super-AND flash produced by Renesas, Or-NAND
flash produce by Micron. It supports 8bit/16bit bus spec, with big/small or large page type of
all kinks of FLASH. With advanced I/O pad process, the controller can support wide I/O
voltage range from 1.8V to 3.3V LVCMOS logic.
MW6208 has a very flexible and configurable interface and internal resource for future
FLASH compatible.
MW6208 supports boot from NAND flash, I
C bus or GPIO logic. Which make support

for future flash process be possible. The firmware can be downloaded to NAND flash
or E
PROM via on chip bus logic. The boot-loader resided in the inner ROM will load the

outer codes if necessary.
The code in the NAND or E
PROM can be used for multi-purpose. For example,

implement user-defined functions such as USB finger-scanner, USB-Key and USB-Ad
Disk. In such application, mounting E
PROM via On-Chip I
C bus prefer to a NAND

flash device.
MW6208 has a UID generating unit implemented by especial process. Which can generate
a Unique Identify Code for each die. The UID is 64bits long and can be read out by
private command. The ID can be used for the application that requires high security.
For example, finance market, personal identify, high security data storage, protecting
your Intellectual Property and so on.
MW6208 has consider this impenetrate its design cycle. Now our controller has optimized
hardware unit for fast and efficiency disk scanning. It provides scan patterns like
memory BIST algorithm. And there are several scan pattern can be configured by user.
With our special hardware support, the disk scanning will achieved the fastest speed and
highest efficiency.
