FRAM instead of Flash — what that changes for your BOM
FRAM writes at bus speed with no erase cycle, consumes roughly 100x less power per write than equivalent Flash, and endures 10^15 write cycles — so this part suits designs that log data, update firmware in the field, or toggle configuration registers frequently without wearing out the memory. The 1 KB SRAM handles stack and scratchpad; the 16 MHz clock is enough for sensor polling, I²C/SPI communication, and control loops in battery-powered or energy-harvesting systems.
Peripheral set and package — what fits on the 16-VQFN
Twelve general-purpose I/O lines break out of the 16-VQFN package (, 4x3.5 mm body). An 8-channel 10-bit ADC handles analog inputs.
TI lists the MSP430FR2310IRGYR with an Active product status. That means no last-time-buy notice is pending, and the part remains in TI's standard production portfolio.
