Dear all,  

 

I am wondering about Anti Fuse technology.  

 

Can anyone briefly describe here what is the main difference beteen Anti Fuse technology and other technologies for FPGA ? The FPGA's based on Anti Fuse technology are just one time programable ? or can we can program them several times ?  

 

Best regards, 

Bilal

Hi, 

as you already mentioned, the Anti-Fuse FPGA are one time programmable only but on the other hand these units are operational on power on, i.e. these units do not need to be configured by a datastream first. 

 

For programming and testing there are meanwhile Anti-Fuse "replacement" devices that can be programmed several times but are pin replacements (i.e. the hardware "around" the FPGA is like on serial hardware).
