Yes. The FX2 can be used to implement the PCMCIA controller. Currently, we do not have any examples or collateral that provide a starting point to implement this. But this can be implemented using the GPIF feature of the FX2.
The FX2 has a feature called the GPIF (The General Programmable InterFace ) which is an extremely flexible 8- or 16-bit parallel interface that can provide a glueless interface between the EZ-USB FX2 and many different types of external peripherals. The GPIF allows the EZ-USB FX to perform local bus mastering to external peripherals using a wide variety of protocols.
