Thread: External SRAM on PIC (or AVR)
picon face BY : Harold Hallikainen email (remove spam text)

       There have been lots of discussions about serial SRAM on the list over
the years. As far as I can tell, there aren't any of any significant size
out there. I WAS using the Dallas RamPort (DS1380 and DS1381) 'til they
discontinued them on us...  I'm now moving designs over the the PIC18c452
which has enough RAM for several products. On one product I'm using the
18c452 with several latches to drive a 128kbyte SRAM (capacitor backed).
That takes several chips. Seems like SOMEONE would make a reasonably
large serial SRAM, but that doesn't seem to be the case.
