OTi-6828

The flash disk controller (OTi-6828) is a disk controller used to make a linear flash device array look likes a normal disk, hiding the flash related problems with erasing.

The OTi-6828 is a controller with USB interface. The USB interface is for full speed operation (12Mb/s). It conforms to USB Specification, Version 1.1. The USB transceiver is embedded in this controller. With stable slew-rate control, the controller reduces EMI.

The OTi-6828 has a Phase Lock Loop (PLL) embedded. The PLL provides all clocks needed in this controller. It needs an externally provided clock operating in 14.318MHz.

The OTi-6828 has integrated the regulator for 5V input and 3.3V output. It also supports voltage detector for power on reset.

The OTi-6828 can control up to 4 pieces of NAND flash memory. The flash capacity can be 32M bits up to 1G bits. And these chips can be any combination. It has been optimized to support Toshiba and Samsung flash memory designs. It also supports Samsung's K9F and K9W Series flash. The controller has write-protected ability to prevent writing data to flash. The controller OTi-6828 has a led control pin. It has three operation modes: suspend (off), active (fast) and idle (twinkle) mode. For read/write operation, the controller can achieve 1,000kB/920kB throughput. Comprehensive application with Windows OS is available.

This controller OTi-6828 can operate in Win XP, Win2000, Windows Me, and Mac OS without any driver installation.

The OTi-6828 is available in cost-saving 32-pin TSOP package.
