We use 100-400 KHz clock depending on other peripherals. Only change major parameters via user interface or computer comm. link when using I2C non-vol backup. The major use in our products use the bytewide parallel SRAM interface to an intel 80188 style uP. These write through in nS bus cycles. We use CRC or checksums and redundancy to protect against loss of power during updates. Batteries not required. Being the software guy, the FRAM is the best, parallel or I2C. Haven't tried the SPI yet.
