Need datasheet / pinout of old Intel PROM C3601 & C3602
On Fri, 4 Feb 2005 00:56:48 +0100 "David Winter"
wrote in Message id: : [sci.electronics.repair & sci.electronics.components added] Hello, I can't find anything about those early PROM chips which are used on a circuit board I need to fix. What board? I need their pinout, if anybody knows where I can find them that would be great. I tried chipdir and similar sites but no luck, they only tell me that one is a 256*4 PROM and the other a 512*4 PROM (we are talking in bytes, not kilobytes, megabytes or gigabytes). These chips date the 1970s. Are the numbers C3601 & C3602 reference designations on the PCB, a label on the chips themselves, or the part # located under the label? The part number under the label is what's most important. Be aware that if these *are* programmable, and you need a replacement, you may be in for a difficult time. |

hi!
here I have put the data sheet of texas 256x4 , 512x4 prom TPB24S10N etc. http://matthieu.benoit.free.fr/TPB24...B28S2708_o.pdf Best regards, Matthieu Franc Zabkar wrote: On Fri, 04 Feb 2005 11:33:04 GMT, (Gerard Bok) put finger to keyboard and composed: On Fri, 04 Feb 2005 06:02:01 -0500, Jay wrote: On Fri, 4 Feb 2005 00:56:48 +0100 "David Winter" wrote in Message id: : [sci.electronics.repair & sci.electronics.components added] Hello, I can't find anything about those early PROM chips which are used on a circuit board I need to fix.

Thanks for your help!
I now have the 3601 pinout, however, no way to get the 3602 one. The Texas collection doesn't include a 512*4 PROM (only a 512*8). I could trick with the two "Enable" pins of the 3601, supposing one was suppressed in the 3602 to serve as A8 address line, but I'm not sure whether all other pins remained unchanged. Anybody can scan his TI Data Catalog for the 3602 (pinout, voltages) ? Thanks to all of you, David.

I've put the Monolithic Memories 63xx family datasheet on ftp://ftp.eskimo.com/u/m/mzenier/MMI63xx.pdf That should give you the 6305 pinout. Mark Zenier Washington State resident |
