kensoft Posted August 30, 2005 Report Share Posted August 30, 2005 Hi,I am new to this forum and pretty new to the electronics world. I came across a bagful of 16-pin DIP marked with the following ...NEC Japan 8227EK213 D4164CNEC Japan 8414D5020 D4164C-3NEC Japan 8350DD122 D416C-2On the exterior of the bag is labelled with marker pen SCR (Silicon Controlled Rectifier)?Does anyone have any idea what these chips are? I have search NEC's site and all of google's results, but can't seem to find any relationships to SCRs.TIA.Kenneth Quote Link to comment Share on other sites More sharing options...
Staigen Posted August 30, 2005 Report Share Posted August 30, 2005 Hi there Kensoft, velcome to the forum :)I belive the chips are 4164 dynamic ram memorys, if i remember right it is 64 Kbit chips, but i'm not shure, they are rather old today :(!//Staigen Quote Link to comment Share on other sites More sharing options...
kensoft Posted September 4, 2005 Author Report Share Posted September 4, 2005 Hi Staigen,You could be right. I wondered how the "SCR" came about. The SCRs that I see in a Google Image search do not appear in DIP packaging.Since the 4164s are 1-bit wide DRAMs, I don't think I can find much use for them. I will probably wire one up to a PIC to see if they really are 4164s.Thanks Quote Link to comment Share on other sites More sharing options...
