UT163 Enhanced USB2.0 Flash Drive Controller
1 Overview
1.1 Description
UT163 is an Advanced Hi-speed USB Flash Disk Controller intended for supporting Flash memory
device and pin-to-pin compatible with UT168/UT166/UT161. It provides enhanced read/write and
power performance. With flexible firmware code design, UT163 can support comprehensive Flash
technologies, including Single Level Cell (SLC), Mutli-Level Cell (MLC) NAND Flash, AG-AND,
NROM and ORNAND Flash memory. It allows the manufacturer to improve device performance and
maximize flexibility in flash decision.
UT163 is a highly integrated single chip for USB2.0 Flash Disk controller, it integrates USB2.0
Transceiver Macrocell Interface (UTMI), the Serial Interface Engine (SIE), one cycle 8032 compatible
8-bit micro-controller and voltage regulators. The highly integration reduces overall cost by minimizing
component amount. Employed leading 0.18um CMOS technology, UT163 is the most cost and power
efficient solution for manufacture.
UT163 has both of hardware and software write-protect capability to prevent writing data into flash
memory unexpectedly and one LED indicator pin to show access status by three operation modes,
Busy, Waiting and OFF. The auto-run function enables comprehensive driver free applications. With
provided utility and mass production tool, UT163 also embodies all best value-added functions, 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.
With excellent compatibility, UT163 can runs smoothly on all PC platforms and support all major Flash
memory. It can support Windows ME/2000/XP, Mac9.x above and Linux 2.4 above without extra driver
and also support Windows 98/98SE through provided driver. UT163 is available in 64, 48 and 80 pin
package. It can accommodate up to 8 flash "CE" pins in 48/64/80 pin packages.
There are 8 IO pins in 64/80pin packages and 16 OUTPUT pins in 80pin package. These 8 GPIO and
16 OUTPUT pins in 80pin package can be used as external NOR flash data and address buses
respectively if "EXT_ROM_ENn" is connected to ground.

3 Application Notes
UT163-L6/T6 are backward compatible with UT161-T6(G)
- 64pin LQFP and TQFP packages are backward compatible with UT161-T6 part, there is no
PCB circuit change required.
- For those new added NC pins, please contact with USBest FAEs for more detail.
UT163-L4 is not pin to pin compatible with UT161-T4(G). New PCB design is required.
UT163-LH is not pin to pin compatible with UT161-LH(G). Existing 80 pin PCB needs minor
modification to fit new pin assignment. Please contact with USBest FAEs for more detail.
