| The World's Fastest USB 2.0 Flash Disk Controller by Silicon Motion Silicon Motion has announced that it has achieved successful customer implementation of the world's fastest USB 2.0 flash disk controller. The company said that its customers have already produced products based on its SM321E and SM324 USB 2.0 flash disk controller chips. Silicon Motion revealed that its customers will release in March new products which will include USB 2.0 flash disk drives with built-in fingerprint sensors and capacity displays based on the SM321E and SM324 flash disk controller chips. The introduction of Silicon Motion's new controllers has raised the bar for the industry's offerings of USB 2.0 flash disk product lines. The SM324 supports dual-channel data transfer at read speeds of 233x (35MB/sec) and write speeds of 160x (24MB/sec), making it the fastest USB 2.0 flash disk controller in the market. The SM324 also has serial peripheral interface (SPI) which allows for not only Master and Slave modes, but gives customers the flexibility to develop more functionality into their USB flash disk (UFD) products such as GPS, fingerprint sensor, Bluetooth and memory-capacity display. In addition to providing faster speed and more functionality than any other UFD controller, Silicon Motion's SM321E and SM324 controllers support more types of flash memory than alternatives offered by other semiconductor companies. Supported memory include SLC and MLC NAND flash from Samsung, Hynix, Toshiba and ST Micro as well as flash products from Renesas, Infineon and Micron. Silicon Motion's SM321E and SM324 UFD controllers also offer high system integration including Power-On-Reset and Regulator in the chip. Post-fabrication support is provided by in-system programming (ISP) which allows for firmware upgrades. Fabrication of the chips is done on a 0.16-micron CMOS process, putting it at the cutting edge of semiconductor fabrication technology and improving both power consumption and performance. Both the SM321E and SM324 UFD controllers support Windows (XP/2000/ME/98/98SE), Mac (OS 9 and X) and Linux (kernel 2.4 and above) operating systems. The SM321E is available in a 48-pin LQFP package and a 44-pin LGA package. The SM321E supports up to 4 SLC or MLC NAND flash chips with 4 bytes / 528 bytes ECC. The SM324 is available in a 64-pin LQFP package. The SM324 supports 8 SLC or MLC NAND flash chips with 4 bytes / 528 bytes ECC. write your comments about the article :: © 2006 Computing News :: home page |
