Do these MCUs replace VNC2?

No, this has no impact on VNC2. We see all families offering excellent value with the common thread that they possess key USB features.

• VNC2 offers 2 x USB2.0 Hi-Speed ports which can be configured as Host or Device
• FT51A offers USB device and hub functionality
• FT900 provides 1 x USB2.0 Hi-Speed host and 1 x USB2.0 Hi-Speed device.

Needless to say, with the FT51A and FT900 we have targeted high performance with features that are key to overall system value.

The FT900 and FT51A provide complete library API source code, unlike the VNC2, giving more flexibility to the developer.
