hello ng,

there are new versions of the 9500xl cpld devices on the xilinx server.

See:

My distri told me, these products are not recommended for new designs, but they still are PRELIMINARY !??

The question about the write inhibit bit is also curious. In ds054

on page 14 table 3 shows a state, where the cpld cannot be reprogrammed nor erased.

Answer database no 4288 states the opposite:

Maybe some stimulations for the next datasheet revisions...

Hi Mike,

Your distributor is wrong in telling you that these 9500XL are not recommended for new designs. It is perfectly fine to start a new design with 9500XL.

Xilinx has absolutely no intention of discontinuing the 9500XL devices. We are still seeing continued interest in new product designs.

As for your technical question below -- Table 3 in the datasheet is incorrect. If read and write protect are both set, then a read will be inhibited, and a program/erase attempt will prompt a Warning in the iMPACT programming software. You can still erase/program the part. In summary, this means you can still erase/reprogram the part even though write protect is set.

We'll fix the datasheet asap...

Thanks! Mark
