Drivers for new Adafruit FRAM boards

Post by pythoncoder » Sat Sep 05, 2020 5:46 am

There is no limit in the code. The practical limit is the fact that each chip requires a separate CS line. I guess with very large numbers capacitance on the SPI bus might slow things down.

I'm deeply impressed by those FRAM boards which now have capacity to rival EEPROM with effectively zero wearout and 200 year data retention. They are fast, too.
