Why would you come to ObsoleteChips.Co.Uk?
You have a product that is mature and still generating revenue but you can’t manufacture because a vital part is no longer available.
You could redesign with a modern part, but that requires a PCB rework and changes to the software!
The PCB design is no longer available, it was done on a system that was retired years ago, so a full redesign will be needed.
The software is in assembler, written by someone who retired 3 years ago and you want to leave it just as it is.
By recreating the part exactly like your current part you overcome all these problems.
Give us a call.
