The controller's firmware supports the latest NAND flash technology from multiple vendors, and is optimized for the highest performance and reliability. The USB controller consists of the functional blocks as shown in Figure 3. The blocks are described in the paragraphs following the figure. Figure 3: Controller block diagram 3.1.1 Controller Internal Components Microcontroller which serves as the hardware backbone for the flash controller algorithm. USB 2.0 Interface Controller with high speed (480 Mbps) device function. This block interfaces with the host system via the USB interface. Flash Interface Controller that serves as the interface to the NAND flash components. It supports all the major NAND flash memory manufacturers. Flash Storage Management Algorithm Block is responsible for the flash management, including wear leveling, bad block management, and Error Correction. ECC block is responsible for on-the-fly error and correction. Sector Buffer for optimized performance. SRAM for running controller firmware fast and efficient. ROM for storing controllers boot code. 61000-07007-104, April 2011 7 SLUFDxxxU2TU(I) Datasheet Industrial Grade USB Flash Drive 3.1.2 Controller External Components In addition to the functional blocks shown in Figure 3, the Industrial Grade UFD has the following external components: SLC NAND Flash for the most reliable data storage. Crystal Oscillator 12Mhz, as the main clock source. 3.2 Flash Management Since the Industrial Grade UFD provides a standard USB interface to the host, no software integration is required, providing the shortest time-to-market for design engineers. The firmware of the embedded USB 2.0 controller contains STEC's advanced flash memory management algorithms to ensure the most optimum device performance, reliability and endurance. It was designed to maximize the benefits of flash memory, while at the same time overcoming inherent NAND flash limitations. Implemented in firmware are the below features: Flash file system management Bad-block management Wear-leveling Performance optimization 3.2.1 Bad Block Management Inherent to NAND flash technology are areas (blocks) on the media that cannot be used for storage because of their high error rate. These so-called "bad blocks" are already identified by the flash vendor during manufacturing, but can also be accumulated over time during device operation. The U2 controller contains a table that lists all the bad blocks on the device (Bad Block Table), and automatically maps out these blocks upon system initialization. During device operation it ensures that newly accumulated bad blocks are also mapped out and added to the Bad Block Table. Bad block management is 100% transparent to the host application, which will not be aware of the location or existence of bad blocks on the media. 61000-07007-104, April 2011 8 SLUFDxxxU2TU(I) Datasheet Industrial Grade USB Flash Drive 3.2.2 Wear Leveling The SLC NAND flash devices that are being used in the USB Flash Drive are guaranteed for 100,000 Write/Erase cycles per block. This means that after approximately 100,000 erase cycles, the erase block has a higher probability for errors than the error rate that is typical to the flash. While 100,000 write/erase cycles may be good for consumer data storage, such as digital cameras, MP3 players, etc., it is not sufficient for industrial and embedded applications where data is constantly written to the device and long product life is required. For example, operating systems that use a file system, will update the File Allocation Table (FAT) every time a write is done to the device. Without any wear leveling in place, the area on the flash where the FAT table is located would wear out faster than other areas, reducing the lifetime of the entire flash device. To overcome this limitation, the flash management algorithm needs to make sure that each block in the device ages, i.e. is "worn out", at the same rate. The built-in wear leveling scheme makes sure that with every write to the flash, the youngest block is used. This ensures that the full flash media is used uniformly, so that one area of the flash will not reach the endurance limits prematurely before other areas. 3.2.3 Error Correction/Detection The USB 2.0 controller implements an advanced Error Correction scheme, based on the BHC error correct algorithm. The ECC engine can correct up to 12-bits per 512 Bytes (symbol based). To ensure the fastest performance, correction is done on-the-fly, in hardware only. Each time the host application writes a sector of 512 bytes to the Industrial Grade UFD, a unique ECC signature is created by the ECC engine and written together with the data to the flash. When the data is read back by the host, the ECC engine creates again the unique ECC signature. It will then compare the original written signature with the newly created signature, and sets an error flag if the two signatures are not the same. Correction of the data is done on-the-fly when the error flag is set, and the data presented to the host will be the same as the original written data an Uncorrectable Bit Error Rate (UBER) of less 14 than 1 in 10 bits, read. 61000-07007-104, April 2011 9 SLUFDxxxU2TU(I) Datasheet 3.3 Industrial Grade USB Flash Drive OS Support The Industrial Grade UFD is recognized as a removable drive and supports the following Operating Systems, as listed in Table 5. Table 5: Supported Operating Systems Operating System Version Windows 98/2000/XP/Vista/Windows 7 Windows XP Embedded Service Pack 2007 Windows CE 4.2 and 5.0 Windows for POS (WEPOS) VxWorks 6.1 and up Linux Kernel 2.4 and up Note: Windows 98 requires driver. 3.3.1 Using USB Flash Drive with XP Embedded When using USB Flash Disk Drive with Windows XP Embedded, it is recommended that the Enhanced Write Filter (EWF) feature is implemented. The EWF intercepts calls at the sector level, and thereby eliminates many file system updates/writes to the flash. Windows XP Embedded Service Pack 2 Feature Pack 2007 introduced an additional write protect feature, called File Based Write Filter (FBWF). The new FBWF function write-protects embedded devices at the file level, in contrast to the EWF, which has been protecting devices at the sector level. FBWF and EWF, combined with the built-in wear leveling algorithm, ensure that the maximum life span of the flash device is achieved. 61000-07007-104, April 2011 10 SLUFDxxxU2TU(I) Datasheet 3.4 Industrial Grade USB Flash Drive Unique Serial Number During manufacturing stage, a unique serial number is written to the USB Flash Disk that includes a date code related to the time of manufacturing.
