The 28 available I/O pins, along with I²C, LINbus, SPI, and UART/USART peripherals, give enough connectivity for a mixed-sensor and actuator cluster without needing an external CAN transceiver on every node. ## Memory sizing for real firmware 8 KB of Flash is enough for a dedicated control loop with a LIN stack and a few hundred lines of application code. The 640-byte EEPROM block is separate from Flash, so calibration tables, fault counters, and production trim values can be updated byte-by-byte without erasing a whole sector. The 1 KB SRAM is tight for buffering — a 256-byte UART FIFO plus a few frame buffers for SPI sensor reads will use most of it. Plan the stack and global variables early in the firmware layout.","metaTitle":"STM8AF6226ITCX 8-bit MCU, 16 MHz, AEC-Q100, 32-LQFP","metaDescription":"STMicroelectronics STM8AF6226ITCX 8-bit MCU with 8 KB Flash, 16 MHz core, AEC-Q100 qualified, -40°C 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":"Tape & Reel (TR)","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":"$0.4000","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/7bf7b21f4a1a887507e01c07ab726cf0.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM8AF6226ITCX/alternatives.json"},"ai":{"faq":[{"question":"How do I get current pricing and availability for STM8AF6226ITCX?","answer":"Submit an RFQ through this listing to receive a current price and availability check from independent distribution."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM8AF6226ITCX","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM8AF6226ITCX when reusing this data.
