OTi-2136 USB 2.0 to CF Bridge Controller

The OTi-2136 presents a cost-effective device which complies with Universal Serial Bus specification rev.2.0 and Compact Flash specification rev 1.4. With OTi’s SOC design expertise, OTi-2136 is single chip solution to provide the bridge function between the USB bus and CF interface. This controller can support various kinds of devices with CF interface, for example, CF card type I, II and micro drive, etc.

The OTi-2136 uses 12MHz crystal and slew-rate controlled pads to reduce the EMI issue. With embedded PLL control circuit and integrated RISC CPU, CF and USB interface controller, this device can certainly grand you the optimize data throughput between USB and CF interface with very low cost.

This controller can operate in Windows XP, Windows 2000, Windows ME, and Mac OS without any driver. The OTi-2136 are available in 64/100-pin LQFP and 64/100-pin TQFP package to provide low-cost solution.
