Product details

STM8S207CBT6TR — 8-bit MCU for industrial control and sensor nodes

On-chip peripherals include brown-out detect, power-on reset, PWM channels, and a watchdog timer, which together reduce the need for external supervisor ICs in cost-sensitive designs.

The 24 MHz clock rate is the headline performance figure for this 8-bit core. At this speed, the STM8 can handle interrupt-driven sensor polling at tens of kilohertz, run PID loops for motor control, and manage serial communication at standard baud rates without bit-banging. For comparison, a 16 MHz 8-bit MCU would leave roughly 33% less headroom for the same code — the extra margin matters when the firmware accumulates over a product's life.

Memory sizing — Flash, RAM, and EEPROM

The 128 KB Flash is partitioned for code and constant data. The 6K x 8 RAM (6 KB) supports moderate stack depth and a handful of moderate-size buffers — enough for a UART FIFO and a few sensor data arrays. The 2K x 8 EEPROM provides non-volatile storage for calibration constants, configuration parameters, and fault logs, with the endurance to survive thousands of write cycles over the product's service life.

No special handling or exemption documentation is needed for standard commercial shipment.

TR suffix — tape-and-reel delivery

The base part STM8S207CBT6 (without TR) ships in trays or tubes. Electrically and functionally the two are identical — the difference is only the shipping medium. For volume production, the TR variant is the standard choice; for prototyping or small-batch builds, the tray version may be more convenient.

Frequently asked questions

What is the difference between STM8S207CBT6 and STM8S207CBT6TR?

The TR suffix indicates tape-and-reel packaging for automated assembly. The base part STM8S207CBT6 ships in trays or tubes. The silicon, firmware, and electrical ratings are identical between the two suffixes.

What development tools work with STM8S207CBT6TR?

STMicroelectronics provides the STVD integrated development environment and the ST-Link programmer/debugger for the STM8 family. Third-party toolchains from Cosmic and IAR also support the STM8 core. The part uses standard SWIM (Single Wire Interface Module) for programming and debugging.
