Product details

What the AEC-Q100 grade means for your BOM

That is not a 'capable' claim — it is a documented qualification that the OEM auditor will accept as PPAP-ready. For any automotive ECU, body controller, or sensor module that must survive thermal cycling and vibration, this part meets the grade-1 threshold at minimum; the extended range suggests grade-0 capability for powertrain-adjacent locations.

16 MHz core — what it delivers in a control loop

The STM8 core runs at 16 MHz with a single-cycle hardware multiplier, so a PID loop or LIN message handler can execute without cycle-count gymnastics. Program memory is 8 KB Flash — enough for a dedicated CAN/LIN node with a state machine and fault logging, but tight for a bootloader-plus-application split. The 1K x 8 RAM and 640 x 8 EEPROM give you non-volatile storage for calibration tables and fault codes without external memory. If the firmware needs more than 8 KB, the STM8A family scales up to 32 KB in the same LQFP-32 footprint.

Peripherals for automotive body and chassis networks

Brown-out detect, POR, PWM, and WDT are integrated, so a simple power supply and a few passives are all you need for a standalone node.

That means no last-time-buy window to schedule, no end-of-life substitution needed for production programs starting today.

Frequently asked questions

What is an alternative to STM8AF6226ITCY?

Within the STM8A family, the STM8AF6226 is the base 8 KB variant. For more program memory, the STM8AF6246 (16 KB Flash) and STM8AF6266 (32 KB Flash) are pin-compatible in the same 32-LQFP package. No second-source from another manufacturer is officially cross-referenced.

How to program STM8AF6226ITCY?

Programming uses STMicroelectronics' SWIM (Single Wire Interface Module) protocol, accessible through the SWIM pin. The ST-LINK/V2 or ST-LINK/V3 debugger handles both programming and debugging. The internal oscillator means no external clock is required during programming.
