描述 Description

UT165 is an Advanced Hi-speed USB Flash Disk Controller intended for supporting new introduced

4KB page flash memories, which need enhanced error correction engine supported devices.

UT165 had been designed as pin-to-pin compatible with UT168/UT166/UT161/UT163. With flexible

firmware code design, all of the comprehensive flash technologies can be supported, including Single

Level Cell (SLC), Mutli-Level Cell (MLC) NAND Flash, AG-AND, and ORNAND flash memory. It

allows the manufacturers to improve device performance or power consumption via maximized

flexibility in flash selection.

UT165 is a highly integrated single chip solution for USB2.0 Flash Disk controller, including USB2.0

Transceiver Macrocell Interface (UTMI), the Serial Interface Engine (SIE), one cycle 8032 compatible

8-bit micro-controller, 8/14-bit ECC engine and voltage regulators. The highly integration reduces

overall cost by minimizing component amount. Employed leading 0.16um CMOS technology, UT165

is the most cost and power efficient solution for manufacture.

There are hardware and software write-protect capability embedded into UT165 design to prevent

writing data into flash memory unexpectedly. One LED indicator pin to show access status by three

operation modes, Busy, Waiting and OFF. The embedded Auto-Run function enables comprehensive

driver free applications. With provided utility and mass production tool, some best value-added

functions can be supported by UT165 controller, such as customized VID/PID/Serial Number, disk

partitions, boot function, and the security function to protect the data against forbid access with

password identification.

Complied with USB specification rev. 2.0, UT165 can be supported without additional driver on

Windows ME/2000/XP/Vista, Mac OS 9.x above and Linux Kernel 2.4 above. With device driver

installed, it can be supported on Windows 98/98SE as well. UT165 is available in 64, 48 and 46pin

packages, and 16/6/4 “CE” pins available respectively.
