Which CPLD is preferrable

[amitjagtap]

Hi all,
I was going thro' CPLD from Altera MAX7000, MAX 9000 and Xilinx XC9500 CPLD families...
I have found some difference (architecture wise) in Altera n Xilinx CPLD. Altera uses EPROM, EEPROM or Flash PROM as an programming element. And EEPROM cell for connection in AND plane.
Where as I haven't found EPROM/EEPROM word in Xilinx XC9500 description sheet.
It is using wired AND connection for programming (as per as my understanding).
Program/Erase Cycles for this is given arround 10,000 times.
Whats about Endurance of EEPROM ( approx).
N Which CPLD is bettter or preferrable as far as commercial market concern.
Thanking you.

Hello
I am not well familiar in details of CPLDs from Altera and Xilinx but once I have made short comparision. As I remember I think that Flash ednurance in Xilinx is bigger than on Altera. But you should considet Lattice CPLDs.

Sorry but I am not able to tell more.

Best regards
