The STM8S208CBT6TR is an 8-bit microcontroller from the STM8S series, built around the STM8 core and clocked at 24 MHz. On-chip peripherals include a 16-channel 10-bit ADC, brown-out detect, power-on reset, PWM, and watchdog timer, reducing external component count for a typical control board.
24 MHz core and memory — sizing the firmware budget
The 24 MHz clock is the ceiling for the STM8 core; at this speed the Flash requires zero wait states for most instructions, so throughput is deterministic for time-critical loops. The 6 KB RAM handles a few hundred bytes of stack and moderate data buffers; if your application needs larger frame buffers or a TCP/IP stack, you will outgrow this part. The 1.5 KB EEPROM is useful for calibration constants, configuration parameters, or fault logs that survive power loss — no external serial EEPROM needed for those tasks.
It is not specified for the full automotive temperature range (125°C) or for under-hood deployment, so keep that in mind if your target environment exceeds 85°C.
The 48-LQFP (7x7 mm) is a standard JEDEC footprint with 0.5 mm pitch. It is surface-mount only, reflow-solderable. The supplier device package is 48-LQFP (7x7). The tape-and-reel variant (the TR suffix) is the standard shipping format for automated pick-and-place; the same die is also available in cut tape for prototype quantities.
ROHS3 compliant.
