16K bit FRAM support?

[Meekdai]

Hi Peter,
I have a project that needs to record the number of motor rotations every 1 second to prevent data loss caused by power down. I want to use FRAM to save my motor rotations data. But M85RS2MT or M85RS4MT is too expensive. For me MB85RC16 (16 K (2 K × 8) Bit I2C) or MB85RS64A (64 K (8 K × 8) Bit SPI) is enough.
Is it possible to let it support small-capacity FRAM for only data reading and writing?

FRAMs are very simple devices to drive. Unfortunately I can't develop a driver for hardware I don't possess so I'm afraid you'll have to adapt the driver yourself. If you do this and have success by all means issue a PR.
