16-bit MSP430 with 15.5 KB FRAM — what the unified memory means for the BOM
The MSP430FR2633IRHBT: FRAM replaces both Flash and EEPROM in one unified non-volatile block — writes are fast (no erase cycle), low-power, and rated for endurance far beyond typical Flash. That makes this part a fit for designs that log sensor data, store calibration constants, or update firmware in the field without wearing out the memory.
32-VQFN footprint — what the kitting lead checks
The 32-VQFN (5x5 mm) with exposed pad is a common package for low-pin-count MCUs.
