General Description:

In March 1993, Xilinx replaced the XC1700 Series PROMS
with the XC1700D family.  There were a number of changes
and improvements in the D family.



Solution 1:

The differences were:

1. New wafer manufacturer (TSMC)
2. Improved ESD protection
3. Availability in a greater variety of packages, including
   SOIC
4. Different programming voltages (therefore different
   programming algorithms are required)
5. Programmable reset capability added
