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.","metaTitle":"STM8AF6226ITCY 8-bit MCU, AEC-Q100, 16 MHz, 8 KB Flash","metaDescription":"STM8AF6226ITCY automotive 8-bit MCU, AEC-Q100 qualified, 16 MHz core, 8 KB Flash, 1 KB RAM, 640 B EEPROM, -40 to 125°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"STMicroelectronics","Speed":"16MHz","Series":"Automotive, AEC-Q100, STM8A","Package":"Tray","RAM Size":"1K x 8","Core Size":"8-Bit","EEPROM Size":"640 x 8","Peripherals":"Brown-out Detect/Reset, POR, PWM, WDT","Connectivity":"I²C, LINbus, SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"28","Core Processor":"STM8A","Package / Case":"32-LQFP","Product Status":"Active","Data Converters":"A/D 7x10b SAR","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM8","Program Memory Size":"8KB (8K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~125°C(TA)","Supplier Device Package":"32-LQFP (7x7)","Voltage - Supply (Vcc/Vdd)":"3V ~ 5.5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.4600","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/7bf7b21f4a1a887507e01c07ab726cf0.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM8AF6226ITCY/alternatives.json"},"ai":{"faq":[{"question":"What is an alternative to STM8AF6226ITCY?","answer":"Within the STM8A family, the STM8AF6226 is the base 8 KB variant.
