The 16 MHz clock is adequate for LIN and I²C bus polling at standard bit rates, but don't expect to run heavy DSP or multi-protocol stacks — the 8-bit architecture and small RAM enforce a lean firmware design. ## NRND — plan your supply chain now That means ST is no longer actively promoting this part for new projects, and the last-time-buy window may already be closing or closed. ## Connectivity and peripherals — what the bus supports LIN handles the low-speed multiplexed bus for switches and actuators; I²C talks to local sensors or EEPROM; SPI connects to a CAN controller if the design needs CAN. The 16 I/O lines are enough for a handful of digital inputs and PWM outputs, but not for a 40-pin dashboard cluster. The 5-channel, 10-bit ADC handles analog inputs like potentiometer position or temperature sensing — adequate resolution for switch-level detection but not for precision measurement. ## Package and rework — 20-TSSOP Housed in a 20-lead TSSOP (4.40 mm body width, 0.65 mm pitch), this part is hand-reworkable with a fine-tip iron or hot-air pencil.","metaTitle":"ST STM8AF6223PCU 8-bit MCU, 16 MHz, AEC-Q100, 20-TSSOP","metaDescription":"STM8AF6223PCU: 8-bit automotive MCU, 16 MHz core, 8 KB Flash, 1 KB RAM, 640 B EEPROM, AEC-Q100, -40°C to 125°C, 20-TSSOP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"NRND","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"STMicroelectronics","Speed":"16MHz","Series":"Automotive, AEC-Q100, STM8A","Package":"Tube","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":"16","Core Processor":"STM8A","Package / Case":"20-TSSOP (0.173\\\", 4.40mm Width)","Product Status":"Not For New Designs","Data Converters":"A/D 5x10b","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":"20-TSSOP","Voltage - Supply (Vcc/Vdd)":"3V ~ 5.5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.4800","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/7bf7b21f4a1a887507e01c07ab726cf0.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM8AF6223PCU/alternatives.json"},"ai":{"faq":[{"question":"Does STM8AF6223PCU support I2C and LIN communication?","answer":"Yes, it includes I²C and LINbus interfaces, along with SPI and UART/USART.
