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. Unlike Flash, FRAM writes at bus speed with no erase-before-write cycle, so you can treat it almost like RAM for data logging or calibration tables without wearing out sectors. 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.
Package and supply voltage range
The exposed pad needs a solid via stitch to the ground plane to keep junction temperatures in check under continuous load.
