Product details

STM8S208C6T6TR — 8-bit MCU with CAN for industrial control

The ST STM8S208C6T6TR is an 8-bit microcontroller built around the STM8 core, clocked at 24 MHz. It carries 32 KB of Flash program memory, 6 KB of RAM, and 2 KB of EEPROM — enough for moderate control loops with a CAN communication stack.

Connectivity and the CANbus decision

The CAN controller is what separates this from the smaller STM8S parts — if your BOM needs a CAN node for a sensor cluster or actuator network, the STM8S208C6T6TR fits without an external CAN controller chip. The 24 MHz core handles the CAN message handling loop without starving the application code.

Supply voltage spans 2.95 V to 5.5 V. Internal oscillator included.

Memory and firmware fit

32 KB of Flash and 6 KB of RAM handle a moderate CANopen or Modbus RTU stack plus the application logic. The 2 KB EEPROM stores calibration constants or node configuration.

Frequently asked questions

What is STM8S208C6T6TR's core speed?

The STM8 core runs at 24 MHz, which sets the timing budget for CAN message handling and UART baud rates.

What is the closest pin-compatible alternative to STM8S208C6T6TR?

The STM8S208C6T6 (non-TR) or the STM8S208C6T6 in the same 48-LQFP footprint are the closest alternatives within the same family. The TR suffix indicates Tape & Reel packaging.
