Patrick,
there's a 1982 "Semiconductor Data Book Hitachi IC Memories" on my desk,
and a scanner in the next room. The book has seven pages about the
HM6116LP-2, HM6116LP-3, and HM6116LP-4, including a general decription,
pinout, data tables, signal waveforms, and various diagrams.
I might send some GIFs by mail to you privately, or if somebody has a
place to make them available on the Web, please let me know. I don't
think Hitachi would mind. I didn't even find a copyright notice in the
book.
Minimum Cycle Time for the "-3" version is 150ns, access times from
either chip select or address input are also 150ns.
Minimum VCC for data retention: 2.0V.
Anything else you need in advance?
Nothing about the Intel chip, however.
Regards,
Andreas

I've 'rescued' a stack of HM6116LP-3 SRAM's from a circuit board. Apart
from the fact that they're 2Kx8 SRAM's, I haven't been able to find any
useful datasheets with both pinouts and timing diagrams for the chips.
By any chance, does anyone have one laying around in PDF or that they'd be
willing to scan? Minimally, I'd like to know the pinout, basic timing
requirements, max clock speed, and data retention voltage.
I've also removed an Intel P8291A, which has been just as hard to find
information on, anything would be useful.
Thanks!
