[OTI]

Description
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 withUSB 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.
