3.1 FTPC Bridge Details
The FTPC Bridge is the interface bridge between the expansion cards, your PC, and the various
applications such as PSoC Express™, PSoC Designer™, and the PSoC Programmer utility.
Since the FTPC Bridge enumerates as a special type of ‘combo device’ that contains a PSoC Mini-
Prog interface, the standard PSoC Programmer utility can identify and communicate with the FTPC
bridge. This ensures that your FirstTouch Kit is automatically compatible with both PSoC Express
and PSoC Designer.
The schematic for the FTPC Bridge shown in Figure 3-1 is found on the CD included in the kit.
