I need to replace a SRAM chip on a piece if test equipment it is a HM62256ALP-8. A 28 pin DIP. It is a 32X8 Hi-Speed SRAM. Can I replace this with any 28 pin SRAM chip or do I need to find an exact replacement or an exact cross reference. Is this like DDR memory in a computer where you can buy what ever is selling at CompUSA? I think I have some chips that are the right speed but trying to find info on if they would work doesn't seem to be that easy. So I thought I would ask you guys.
Thanks so much Russ
