I'm looking for at least  1 MB, so that's 8 of those babies, so then it gets
to be a pcb space issue.

 

The reason I'm trying to avoid SPI is just the usual I/O pin scarcity and I
already have three I2C devices so am  committed to that bus regardless.
Memory is the only reason for SPI.   Of course, I can solve the I/O pin
scarcity by multiplexing but I'd like to avoid that too.  I2C memory seemed
like a good solution.if it were available in the capacity I'm looking for.
If that is impossible, well it'll have to be SPI and use multiplexing for
some I/O pins.

Why do you want to stay away from SPI? In any case, would 2 of these work
for you?

I need much higher capacity, 1 MB (8 Mbit) minimum, for data logging.
