FRAM at 24 MHz — the architecture that changes the memory trade-off
The MSP430FR5734IPW: The core runs at 24 MHz, and the 1K x 8 RAM handles stack and scratchpad data. FRAM eliminates the write-endurance worry of EEPROM: you can log sensor data or update configuration tables every cycle without wearing out the memory, which is the main reason this part gets specified in metering, data-logging, and industrial sensor nodes.
When sourcing, confirm the specific I/O and memory configuration matches your firmware image — the 8 KB FRAM and 1K x 8 RAM are fixed for this order code.
