Product details

The STM8S208C6T3 is an 8-bit microcontroller from STMicroelectronics' STM8S series, built around the STM8 core running at 24 MHz. The 48-LQFP package (7x7 mm) gives you 38 I/O lines and a peripheral set that includes CAN, I²C, IrDA, LINbus, SPI, and UART/USART, plus a 10-channel 10-bit ADC.

24 MHz core and memory sizing — what fits

The 24 MHz clock is the ceiling for this 8-bit core; at that speed the Flash requires zero wait states for most instructions, so throughput is deterministic for time-critical loops. The 32 KB Flash is a mid-density option — enough for a CAN node with bootloader, some PID loops, and a modest protocol stack. If your firmware image is pushing past 28 KB, you'll want to audit the linker map before committing. The 6K x 8 RAM handles a few packet buffers and stack; for data-heavy applications the 2K x 8 EEPROM can store calibration constants or fault logs without wearing the Flash.

It's a current-production part you can specify into a new BOM without obsolescence risk.

Frequently asked questions

What are the differences between STM8S208C6T3 and STM8S208C6T6?

The two parts share the same die, Flash size, RAM, and peripheral set. If your application sees sustained temperatures above 85°C, the C6T3 is the correct choice.
