The STMS207SB performance line 8-bit microcontrollers offer from 32 to 128 Kbytes Flash program memory. They are referred to as high-density devices in the STM8S microcontroler family reference manual.

It provides the following benefits: reduced system cost, performance robustness, short development cycles, and product longevity
