Tell me analogues of DALLAS DS1285, please.
ZXNet echo conference «hardware.zx»
Hello, All
Over the centuries, the DS1285 on my board has long since died. I want to stick it in its place
new, but DS1285 is nowhere to be found. I found information that there is such a DS12885, just
sharpened for a hemorrhoid-free replacement for 1285, but they are also not available anywhere. :(
Are there complete analogues of these microcircuits from other manufacturers?
I also found DS12887 in the store, but I don’t know if it fits or not, based on its appearance
It looks like it, but I don’t really want to risk 200 rubles...
Please tell me something smart :) it is very desirable that without using
I didn't need a soldering iron :)

Data from this page: "DS12887 is identical to DS12885."
And a line from the attached datasheet:
"DESCRIPTION
The DS12885 Real Time Clock plus RAM is designed to be a direct replacement for
the DS1285. The DS12885 is identical in form, fit, and function to the
DS1285..."
It turns out that DS12887 = DS12885 = DS1285.
Buy it or something...
PS; A; DS1387, -1397 and -1487, I couldn’t find it in our stores :(

Hello Ronin
The first one, if I'm not mistaken, was bought from a guy. Well, a very long time ago
Hello, acidrain
If I were a virtuoso in English, I would probably cope with such a task with
100% accurate. But... now I’m inclined that 12887 is suitable, but it’s still full
I'm not sure, that's why I'm asking.
Hello, Evgeny Muchkin
like where :) and where did you first get it :) from old PC motherboards!

To begin with, name at least the device in which you use this RTC.
Secondly, why the immediate fear of the soldering iron? There is an option to simply replace
(more precisely, connect in parallel) the battery. Trident did it, old guys
the watch at SMUC continued its life, albeit with a prosthesis :)
You can also scroll through the topic “SMUC on discretes”, questions were raised there
RTC analogues.

Everything is done very simply - you search for datasheets on these chips on Google and read
carefully what is written in them. =)
