FRAM-based MSP430: what the 128 KB nonvolatile memory means for your BOM
Its program memory is 128 KB of FRAM — a nonvolatile technology that combines the fast write speed and low power of SRAM with the retention of Flash, and it is byte-addressable. The 2 KB of conventional RAM handles stack and scratchpad data. With 63 general-purpose I/O lines, a 12-channel 12-bit ADC, and serial interfaces including I²C, SPI, and UART, this part targets industrial sensing, metering, and battery-powered instrumentation where every microamp of quiescent current and every write-cycle budget matters.
At the low end, 1.8 V is the minimum for FRAM read/write integrity — a brown-out detector (included in the peripheral set) resets the core if the rail dips below that threshold.
The 80-LQFP package (12x12 mm body) is a standard fine-pitch QFP that reflows with a typical lead-free profile; no special bake is needed if the moisture barrier bag is intact, though the MSL rating should be verified from the reel label before rework.
