So I am trying to replace an old 5101 ram that came stock in my Bally Mata Hari pinball machine. The 5101 has gone bad, and even when its working requires batteries to hold its memory. So why not replace it with a new NVRAM that doesnt require batteries, etc. So thats the idea.
I got a new NVRAM from ramtron, which is a 28 pin package, the old 5101 is just 22 pins. Here are the data sheets for both
5101: http://www.pinballpcb.com/datasheets/Intersil5101.pdf
RAMTRON: http://www.ramtron.com/files/datasheets/FM16W08_ds.pdf
So I am somewhat of an electronics amateur and (no formal training) and am having trouble doing some of the pin translations, here is what I have got so far (X means unused/not needed):
RAMTRON to 5101
01 to X
02 to X
03 to 7
04 to 6
05 to 5
06 to 21
07 to 1
08 to 2
09 to 3
10 to 4
11 to
12 to
13 to
14 to 8
15 to
16 to
17 to
18 to
19 to
20 to 19
22 to 18
23 to X
24 to X
25 to X
26 to X
27 to 20
28 to 22
If anyone could have a look at the data sheets, check this over, and help me complete it, I would be very grateful. Thanks!
