FRAM memory array....
I am designing a memory array of 16 or possibly 32 FRAM (SPI) devices for a battery operated datalogger for remote outdoor location. I have looked at the DC Characteristic in the datasheet for CY15B104Q (512K x 8) in particular the I/O voltage thresholds, Ioh, Iol and ILi figures. From these figures it is possible to construct an array of 32 devices. The design has individual /CS for each device so only one device is active and the rest tri-stated. My real concern is the Input capacitance that would be in the region of 6x32=192pf + board layout capacitance..Could you please comment on this. Many thanks for the help.
