24 MHz 8-bit MCU with CAN — fit for industrial control nodes
The STMicroelectronics STM8S208S6T6C is an 8-bit MCU from the STM8S value line, built around the STM8 core running at 24 MHz.
Peripheral set and I/O — what connects where
34 I/O lines are available on the 44-LQFP package (10x10 mm body). A 9-channel 10-bit ADC is on-chip for analog inputs like potentiometers, thermistors, or current-sense resistors.
Memory sizing — what fits in 32 KB Flash and 6 KB RAM
32 KB of Flash (32K x 8) is the program store. For a typical industrial control application — say a CANopen slave with a few analog inputs and a PWM output — that leaves room for a modest RTOS kernel, the protocol stack, and application logic. The 1.5 KB EEPROM is useful for calibration constants or configuration parameters that survive firmware updates.
That means ST continues to manufacture it, no last-time-buy window is open, and the part is available through franchised distribution.
We source the STM8S208S6T6C through our independent distribution network. Because the part is active, lead times are generally stable, but we can pull from multiple inventory pools to cover a BOM line when franchised channels are tight.
