Product details

24 MHz 8-bit MCU with 128 KB Flash — the BOM-fit tier

It comes in a 64-pin LQFP package with a 10x10 mm body — a footprint that is hand-solderable and rework-friendly with a standard hot-air station.

128 KB Flash, 6 KB RAM, 2 KB EEPROM — sizing the firmware and data budget

The 6 KB RAM handles moderate data buffers for UART or SPI transactions; if your application streams sensor data or runs a TCP/IP stack, budget the RAM against the stack's footprint. The 2 KB EEPROM is a genuine differentiator: it stores calibration constants, configuration parameters, or fault logs without needing an external serial EEPROM, and it survives 100k write cycles per the STM8S family spec.

At the hot end, the 24 MHz clock may need a wait-state adjustment if the internal oscillator drifts; ST's datasheet provides the derating curve.

64-LQFP (10x10) — rework and footprint

The 10x10 mm body has moderate thermal mass; a 260°C peak reflow profile per J-STD-020 works fine. The package is MSL 3 — bake at 125°C for 24 hours if the moisture-barrier bag has been open longer than the floor-life window.

ST lists this part as Active.

Frequently asked questions

What is the difference between STM8S207RBT6 and STM8S207RBT6TR?

The STM8S207RBT6TR is the Tape & Reel packaged version of the STM8S207RBT6. The die, firmware, and electrical specifications are identical. The 'TR' suffix indicates reel packaging for automated pick-and-place assembly; the base part number STM8S207RBT6 refers to the tray-packaged variant.

Does STM8S207RBT6TR require an external oscillator?

No. The STM8S207RBT6TR has an internal oscillator. It can run from the internal RC clock without an external crystal or resonator, though an external clock source can be used if tighter timing accuracy is needed.

What is the closest pin-compatible alternative to STM8S207RBT6TR in this family?

Within the STM8S207 series, the STM8S207RBT6 (tray package) is pin-compatible and functionally identical. The STM8S207R8T6 offers 64 KB Flash instead of 128 KB, but shares the same 64-LQFP footprint and peripheral set — a drop-in replacement if code size is not the constraint.
