FRAM MCU for low-power sensor and control nodes
The MSP430FR5724IRGER: 16-bit MCU with 8 MHz core, 8 KB FRAM, and 1K x 8 RAM.
8 MHz — enough for sensor polling and communication
At 8 MHz the core polls an 8-channel 10-bit ADC and communicates over UART or SPI without stalling.
FRAM memory: no field-update penalty
The 8 KB FRAM program memory is the headline feature. Endurance is effectively unlimited — no wear-leveling code required. For a design that stores configuration data or event logs in the same memory space as code, this simplifies the firmware architecture.
