FRAM is pretty neat. I considered using an MSP430FR5969-SP for a component on a satellite but backed off when I learned more about the destructive read process.

FRAM is pretty neat. I considered using an MSP430FR5969-SP for a component on a satellite but backed off when I learned more about the destructive read process. We were concerned about a transient bitflip during the write back and had no where safe to store program code other than the FRAM itself. Instead, we went with a RISC-V core in an FPGA and used an 8 channel ADC to cover the telemetry reporting the MSP430 was supposed to handle. I spent a lot of time writing fast, safe code for it so was a little disappointed it never made it into the final design.
