First question asked Welcome!

I am currently using a Cyprus CY14B101I in one of our product lines. This has an i2c bus interface and provides 128K bytes of storage.

I am looking for a larger storage option ideally 512K Bytes and found your FRAM pages mention larger storage option for i2c, SPI and QSPI. But when I go into product selection I can't see any devices which provide an i2c interface, only SPI.

Please advise if you have any i2c storage options for 256K Bytes or larger.

Thanks

Hi @michaelsimp ,

 

In our portfolio, we do not have any I2C storage options for 256K Bytes or larger. Maximum is 128K bytes for both FRAM and nvSRAM parts with I2C interface.

 

Thanks,

Ritwick
