8.5 KB FRAM — the write-without-wear memory
The 1K x 8 RAM handles stack and scratchpad.
16 MHz core, 60 I/O, industrial temperature
The CPU16 runs at 16 MHz — enough for sensor polling, communication protocol handling, and control loops in the low-power domain this family targets.
The exposed pad is not present on this LQFP variant, so all thermal dissipation goes through the leads; keep the ambient airflow adequate if running continuous PWM loads near the 85°C limit.
For volume production or long-term BOM planning, this part presents no LTB risk in the near term.
