Hi Ruud,

you asked me about larger than 32k SRAMs some time ago
(probably interesting for the others as well...)

http://semiconductor.hitachi.com/search97cgi/s97_cgi?ServerKey=Primary&collection=Products&ResultTemplate=browsetree.nick&ResultStyle=normal&ClusterPageSize=5&ClusterCount=5&QueryText=line+%3Ccontains%3E+Medium+Speed+SRAM&SEARCH-97.x=58&SEARCH-97.y=20?hit_code=MED-SPEED
Try the HM628512B Series or HM628512AI Series for 5V 512k*8 types.
The HM628512A Series (second page) is not even preliminary :-)

or on http://mot-sps.com/sps/General/chips-nav.html
search for MCM6246 - Oops, that's available in SOJ package only.

Hm, let's look here:
http://www.mitsubishichips.com/data/datasheets/psgindex.html
D*mn. They only have 3.3V 512k*8, and only SOJ package.

Hm, the chip directory: http://www.xs4all.nl/~ganswijk/chipdir/f/sram.htm
only has the Hitachi IC...
(Anyway, there are others, like 128k*8)

I thought there were more manufactures. Anyone else?

Are there sockets for SOJ packages that fit into the 2.54mm raster?

Andre
