Anti Fuse Programmed FPGA

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).
