At 16 MHz, this core handles a 1 ms control loop with margin for LIN message handling and ADC reads. That is not a high-speed DSP number, but it is the right fit for a relay-coil driver or a brush-DC motor controller where the plant time constant is tens of milliseconds. If you are starting a new design, look at the active STM8A family members with similar pinouts and peripheral sets; the 32-LQFP footprint is common across several density options. Brown-out detect and POR keep the firmware from corrupting Flash on a sagging supply. Housed in a 32-LQFP (7x7 mm) surface-mount package, with 28 I/O brought out. The pitch is standard for hand-assembly and reflow alike.","metaTitle":"ST STM8AF6226TCY 8-bit MCU, AEC-Q100, 16 MHz, 32-LQFP","metaDescription":"STM8AF6226TCY automotive 8-bit MCU, 16 MHz, 8 KB Flash, AEC-Q100, -40 to 125°C.
