|AN-003: W65C134S Replacement Notes for 8-bit Microcontrollers|
|R6511Q and W65C134S COMPARISON CHART|
|R6511Q vs W65C134SPL|
1. NC=No Connect
2. NA=Not Available on R6511Q
3. Note: All W65c134SPL IO pins have bus holding devices.
4. The W65C134SPL does not have the ability of dividing the incoming clock. Therefore, PHI2 is the same frequency as the clock. The 11Q has the ability to divide the incoming clock input by 1, 2 or 4.
