Oh noo bad news .... must do 900km for aquire one ... from the neighboor country ...
Last 2 very stupid Q:
1_ Prom is refleshable more than One time ? (when hear PROM i remember something OTP)
2_ Is there requirements on what minimal model can I use with the XC2S200-208 device ?
(I strongly prefer non BGA pinout PROM because lack of PCB)
_ONLY_ what can I aquire is:
For Spartan Family:
XC17S05PD8C
XC17S10XLPD8C
XC17S10XLVO8C
XC17S20PD8C
XC17S20XLPD8C
XC17S30PD8C
XC17S30PD8I
XC17S30XLPD8C
XC17S40PD8C
XC17S40XLPD8C
XC17S40XLSO20C
Any of these are enough capacity ?
Thanks again a lot !
