Appendix A4. Synchronous and asynchronous timing selection
AX88180 can support synchronous or asynchronous access from host MCU. Below information provides some
references to select clock frequency of host MCU and AX88180.
A4-1. AX88180 is synchronous with host MCU.
The timing selection is suitable for both 32-bit and 16-bit mode.
Frequency
Access type
Valid access timing (OEN/WEN active timing)
Max 100MHz
Single or Burst
Min 5 clocks
A4-2. AX88180 is asynchronous to host MCU.
The timing selection is suitable for both 32-bit and 16-bit mode.
Frequency
Access type
Valid access timing (OEN/WEN active timing)
Max 100MHz
Single or Burst
Min 6 reference clocks (Note)
Note:
The reference clock is from OSC, and it’s not the output of host MCU. For instance, if AX88180 runs in
asynchronous mode and refers a 100MHz clock from OSC, whereas MCU runs in 125MHz environment. In
such condition, MCU must at least offer
60ns (min 6 reference clock of 100MHz) access timing to AX88180.
The 60ns for MCU is almost reached to 8 clocks (125MHz). We recommend that it is needed to extend the
access timing of MCU to AX88180.
