Question: Is there any Trise and Tfall (slew rate) requirement for the input of the Xtal input (Xin) of CY23FS04? Is the input pin (Xin) 5V tolerant?
The XIN and XOUT are crystal input pins for CY23FS04. It is designed to use a crystal connected between the XIN and XOUT pins. The standard waveform of crystal output is sine wave. The CY23FS04 supports standard crystal output waveform. Input pin is 5V tolerant.
