All,
Before I begin this experiment, is it even possible to use the APS6404L (or any other SRAM chip) as data storage device for a Teensy 3.2 or Teensy 4.0? I see it can be soldered to a 4.1, but since according to the data sheet it's an SPI device, so maybe it can be used on the smaller chips
My usage of SD cards for data storage works fine, but always looking for alternatives. Since this chip is an SPI device, maybe I can connect it to the Teensy 4.0's SPI buss and write data to it? If it's possible, I'll look at writing a lib to make storage and retrieval easy.
questions
1. think this chip can be connected to the SPI buss and be used to store data on a 3.2/4.0?
2. will this chip retain data after power off (data sheet says yes, but not sure i'm reading it right--Pseudo is confusing me)
3. Anyone tried this before?
I don't mind buying one and playing around, but if it's not even possible, I'll spend my time on something else
Thanks in advance
Kris
