16 MHz core, 4 KB Flash — what the memory budget means for your firmware
That memory footprint targets compact control firmware — state machines, sensor polling loops, communication protocol stacks — rather than data-logging or GUI-intensive applications.
Industrial temperature grade — deployment in harsh environments
The 32-VFQFN exposed-pad package (5x5 mm) aids thermal dissipation when the part is running continuous ADC conversions or PWM outputs at elevated ambient temperatures.
For a procurement decision, this means the BOM line can be committed without obsolescence contingency planning. The part is RoHS3 compliant.
Connectivity and peripherals — what is on-chip
On-chip peripherals include brown-out detect and reset (BOR/POR), PWM outputs, and a watchdog timer. The 10-bit ADC with 8 channels handles analog inputs like temperature or current sense without an external converter. 24 general-purpose I/O pins are available in the 32-VQFN package.
