Obsolescence of reverse TSOP packages

Good day to all.



I am facing a problem with flash memories. I have a number of products with 8/16 bits microprocessors that use Amd (Spansion) 5V/3V3 1MBit or



4 Mbit Flash memories.

The so-called reverse TSOP package that is so interesting when used face to face with the standard TSOP package (one on each side of a PCB) is being obsoleted by Spansion.



The reverse package has been abandoned by Thomson earlier.



Any idea other than redesigning the PCB, which by the way is not immediate at all ?



Like for instance using a mechanical tool that would bend the leads the reverse way (with probably some danger of embrittlement of the leads).



Anything else ?

If they are still available now: Buy enough to last till you do need a redesign.

Sounds possible, but indeed not the preferred option.

If thickness is not a problem then design a PCB "ring" that will allow you to solder the standard package on to the reverse package layout.

Are the parts available in die form? Are you willing to pay a premium? You can buy the parts in die form, or even as unseparated wafers, and have them packaged however you want.

for instance.
