FRAM at 16 MHz — what the MSP430FR5967IRGZT brings to the BOM
For a design targeting sub-100 µA active draw with frequent data logging or field firmware updates, FRAM eliminates the erase-page latency and wear-leveling overhead that Flash imposes. The 1 KB of SRAM handles the stack and scratch buffers. The part carries 40 GPIOs and a 16-channel 12-bit ADC, making it a fit for sensor-heavy industrial or portable instrumentation boards where analog acquisition and low sleep current are the primary constraints.
Connectivity and peripherals for sensor fusion
The 16-channel 12-bit ADC can sample analog inputs at a rate suitable for slow-loop process control or battery monitoring. DMA offloads data movement from the CPUXV2, letting the core stay in low-power sleep while the ADC fills a buffer.
Supplied in a 48-VFQFN exposed-pad package, the 7x7 mm body requires a thermal pad via-stitched to the ground plane to pull heat from the die. The exposed pad is also the primary electrical ground connection — a poor solder joint here can cause intermittent brown-out resets. The cut-tape and reel options cover both prototype and production volumes.
