CY7C646xx EZ-USB FX microcontroller

Question: Can the CY7C646xx EZ-USB FX microcontroller operate at 48MHz when booted from external EPROM 8 bit parallel program memory (FLASH), when EA=1?

 

Answer:

The only way to run the EZ-USB FX at 48 MHz is to have an external I2C EEPROM with that bit set.
