Its program memory is 64 KB of FRAM — non-volatile, fast-write memory that eliminates the erase-cycle overhead of Flash and keeps data intact through power loss. With 2K x 8 of RAM and 40 I/O lines, it's sized for sensor-fusion, metering, and battery-powered control applications where every microamp matters.
FRAM memory — why it changes the firmware strategy
The 64 KB FRAM program memory is the headline feature here. The endurance is orders of magnitude higher than typical EEPROM, and the write current is lower — a real advantage in energy-harvesting or coin-cell designs.
Industrial temperature and on-chip analog
The 16-channel 12-bit ADC covers analog inputs from multiple sensors — thermocouples, shunt resistors, or bridge circuits — reducing external mux and signal-conditioning BOM cost.
