96 KB FRAM — why it matters for this MCU
Its 96 KB of FRAM program memory is the standout feature: FRAM writes nearly as fast as SRAM, draws negligible power during write, and retains data without a battery. That makes it a fit for metering, medical logging, and any design where you need to store calibration constants or firmware updates without worrying about Flash write endurance or erase cycles.

The 2K x 8 RAM is modest — enough for small buffers and stack — but the FRAM can absorb data-logging storage directly.
