Question: Can a ceramic resonator be used instead of a crystal for CY7C64x13, CY7C65x13 and CY7C66x13?
Answer:
The CY7C64x13, CY7C65x13 and CY7C66x13 all require a crystal or an external clock source. A ceramic resonator does not allow the microcontroller to meet the timing specifications of full speed USB and therefore a ceramic resonator is not recommended for these parts.
