Hi,
I found a mystery chip in a pile of stuff. Apparently, it was an AWARD
BIOS in a former life. I can read it in my EPROM programmer and it is
read
compatible with a 27C512 (64Kx8 EPROM). The contents
are consistent with
an AWARD BIOS for a PC of some sort.
However, the chip itself is rather unusual. There is no EPROM quartz
window, the manufacturer symbol is a triangle, and the number is unlike
anything I have seen before. Worse yet, I get no helpful hints on GOOGLE
when I try.
The chip number is 608C62. I am guessing it is either
a One Time PROM or
a
mask ROM. Has anyone heard of this or know what
family it is from?
I found it on www.datasheets.org.uk - it's listed as an equivalent to a
6264 static ram, which sounds plausible...

I am hoping it was a FLASH ROM or EEPROM but I
can't seem to find anything
on this chip. Any hints or help much appreciated!

Hi Julian, Thanks for looking and the reply. That is the first place I went
after Google looking for a datasheet.
The only thing they said though was that I was not the only person who has
searched for the device in the past.
The chip is some sort of ROM because I can read the contents with my EPROM
programmer in 27C512 mode. No luck on what it is though...
At least it is not unique but it is starting to look a lot like a Mask ROM
to me.
Thanks!
