STM8S207K8T6CTR

The maximum CPU frequency of the STM8S207xx and STM8S208xx microcontrollers in the performance line is up to 24 MHz.

The STM8S207xx microcontroller supports external interrupts on Port A, Port B, Port C, Port D, and Port E, totaling 5 external interrupts. The STM8S208xx microcontroller supports external interrupts on Port A, Port B, Port C, and Port D, totaling 4 external interrupts.

The unique feature that provides a 96-bit unique key for each device in the STM8S207xx and STM8S208xx microcontrollers is the Unique ID. This 96-bit unique device identifier cannot be altered by the user and can be read in single bytes, then concatenated using a custom algorithm. The Unique ID is ideally suited for various purposes such as serial numbers, security keys for code security, activating secure boot processes, and combining with software cryptographic primitives and protocols before programming the internal memory.
