With 51 I/O lines in a 64-LQFP package, it suits applications that need a moderate pin count for parallel interfaces or multiple sensor inputs.
Where it fits — industrial and outdoor environments
The 105°C ceiling covers engine-bay-adjacent enclosures and sealed sensor nodes that see solar loading.
Memory map and peripheral set
The 128 KB Flash is organised as 128K x 8, the 20 KB RAM as 20K x 8, and the 6 KB EEPROM as 6K x 8. The 12-bit ADC with 16 multiplexed channels covers analog sensor acquisition without an external converter.
