Hmmm, why are these so hard to find?
I already have 16megabit SPI serial EEPROMs, cheap enough and they come in a 8pin package.
I'm working on a datalogger app and need similar storage, ie 16Mbit or maybe 32Mbit, but don't want to use EEPROMs as this logger has internal rechargable battery so is never powered down, and I don't want the power and time costs of "saving" data to EEPROM, both of which are significant.
So what I am after is a static RAM that will be permently powered, and draws a handful of uA in standby. That is common enough, but I need it to have serial input so it only uses 3 or 4 input pins, and a small footprint ie 8 pin package preferred.
I checked Microchip as they have a serial static RAM but it is stupidly tiny! Can anyone please suggest a small pin count SPI serial static RAM with a large memory?
Thank you!
