Please note the following points when considering migration with EPM570T144 and EPM1270T144.
1: Bank configuration is different.
The EPM570 has a 2-bank configuration, and the EPM1270 has a 4-bank configuration.
If the EPM1270 uses a different VCCIO, it may not be configurable with the EPM570.
2: Bank3 of EPM1270 has PCI clamping diode function. EPM570 does not have that function.
Hmm.
 
For details, please refer to the MAX II Device Handbook at the URL link below and search for keywords "Banks" and "PCI clamping diode".
