6. HARD CORE MODEL
The W65C22C is functionally equivalent to the W65C22S except it does not have the output drive
transistors and does not have ESD protection.
If Chip Select, CS1 is not used, it should be held in the high state. If Chip Select, CS2B, is not used it
should be held in the low state.
The timing of the W65C22C is the same as the W65C22S in that the input buffers are the same and the
output transistor drivers are the same as the W65C22S. When applying the W65C22S core, the output
delays should be analyzed after adding the output drive transistors and the output load capacitance.
