The STM8S207R8T6 is an 8-bit MCU from ST's STM8S value line, built around the STM8 core and clocked at 24 MHz.
The part is ROHS3 compliant, and the base STM8S family has broad toolchain support (ST Visual Develop, Cosmic, IAR) and the ST-Link debug probe — no special adapter needed.
Yes, the oscillator type is listed as Internal, so no external crystal or ceramic resonator is required for basic clocking. The 24 MHz core speed runs from the internal RC oscillator.
The STM8S207R8T6 and STM8S207RBT6 share the same 64-LQFP footprint and the same STM8S207 base part number, so they are pin-compatible. The difference is Flash density: 64 KB on the R8 versus 128 KB on the RB. If your firmware fits in 64 KB, the R8 is a drop-in replacement.
The STM8S family is supported by ST Visual Develop (free IDE), Cosmic C compiler, IAR Embedded Workbench, and the ST-Link/V2 debugger/programmer. The SWIM debug interface is standard across the STM8S line.
