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.
