UT161
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.
