芯片简介：
联盛半导体(USBest)主要由联电(UMC)与硅统于2002年12月策略合作成立的，是联电集团旗下的IC设计公司，定位以『记忆储存装置』及『接口传输技术』作为产品发展的主轴，2003年11月领先市场以 0.18微米制程开发出颗粒最小、读写速度快的随身碟控制芯片，目前已是市场上主要的供应厂商。
随身碟（U盘）、卡片阅读机（读卡器）、快闪记忆卡（SD卡控制器）是联盛(USBest)的主力产品。
读卡器（Card Reader）控制器系列IC，是联盛（USBest）未来的主力产品，其优势在于产品全面，在读/写速度、稳定性、兼容性等方面，与同类产品相比处于领先地位：UT330、UT335、UT336、UT311系列。尤为值得关注的是增加了智能卡（Smart Card Reader）读卡器及手机卡（SIM Card Reader）读卡器功能的UT360、UT367系列产品，为客户提供了更大的价值。
UT330
The UT330 is a USB 2.0 Multi Interface Flash Card Reader Controller by a highly integrated single chip solution that enables users to enjoy high-speed transmission between buses of USB 2.0 and versatile flash card interfaces with up-to-date specification for each.
The UT330 enables PC/NB, MFP, DVD, TV… that with USB 2.0 to read/write various type of flash media cards including CompactFlash™ (CF) TypeI/II, Micro Drive (MD), Security Digital™ (SD), MiniSD™, MicroSD, TransFlash™ (T-Flash), High Speed SD (HS-SD), High Capacity SD (SDHC), MultiMediaCard™ (MMC), Reduced Size MultiMediaCard™ (RS-MMC), High Speed MMC (HS-MMC), MMCmobile™, MMCplus™, MMCmicro, High Capacity MMC (HC-MMC), Memory Stick™ (MS), Memory Stick Duo™ (MS Duo), High Speed Memory Stick™ (HS-MS), Memory Stick PRO™ (MS-PRO), Memory Stick PRO™ Duo (MS-PRO Duo), Memory Stick PRO™ Duo HG (MS-PRO Duo HG), Memory Stick ROM, Memory Stick Micro (M2™), SmartMedia™ (SM), and xD-Picture Card™ including Type M and Type H on a single chip. It also supports Microsoft Windows Vista™ EMD ReadyBoost™ function in order to speed up PC/NB system by utilizing the available space on the memory card.
The UT330 integrates a high speed 1T 8051 microprocessor and a high efficiency DMA hardware engine for the best data transfer performance between USB and flash card interfaces. Bedsides, it also builds in five MOSFET switches for power control of each card and POR (Power On Reset) circuit to save BOM cost. A serial EEPROM interface is provided to store customized information such as VID/PID, serial number, string, LUN number corresponding supported card type, LED number and blinking style… and so on.
The UT330 supports dual independent SD/MMC interfaces for concurrent access between SD/MMC and MicroSD/MMCmicro/T-Flash. With external NOR flash read/write interface, the UT330 supports firmware upgrade ISP (In System Programming) function via USB interface.
The UT330 complies with USB specification Rev. 2.0 and USB Mass Storage Class specification Rev. 1.0 such as to be easily supported without additional driver under Windows ME/2000/XP/Vista, Mac OS 10.x above, and Linux Kernel 2.4 above. With device driver installed, it can be supported on Windows 98/98SE and Mac OS 9.x as well.
The UT330-LF is packaged with 128-pin LQFP (14mm x 14mm x 1.4mm) for up to 5 LUNs (CF, SD/MMC, MS, xD/SM, MicroSD/MMCmicro/T-Flash) multi flash card reader applications with ISP function.
