The 2K SRAM handles a few buffered CAN frames or a modest state machine; if your application needs more than a handful of 8-byte messages queued, budget the RAM headroom against the 2K ceiling. ## Wide supply and industrial temperature — where it runs ## Peripherals and I/O — what connects The 7-channel 10-bit ADC handles analog inputs like temperature or position sensors. PWM and WDT are on-chip for motor-drive timing and watchdog supervision. Housed in a 32-VFQFN with exposed pad, surface-mount only.","metaTitle":"STM8AF6266UAY 8-bit MCU, 16 MHz, 32 KB Flash, -40 to 85°C","metaDescription":"STMicroelectronics STM8AF6266UAY 8-bit MCU with 16 MHz core, 32 KB Flash, 2K RAM, 1K EEPROM, industrial temp range -40 to 85°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":"STM8A","Package":"Tray","RAM Size":"2K x 8","Core Size":"8-Bit","EEPROM Size":"1K x 8","Peripherals":"Brown-out Detect/Reset, POR, PWM, WDT","Connectivity":"I²C, LINbus, SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"25","Core Processor":"STM8A","Package / Case":"32-VFQFN Exposed Pad","Product Status":"Active","Data Converters":"A/D 7x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM8","Program Memory Size":"32KB (32K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 85°C (TA)","Voltage - Supply (Vcc/Vdd)":"3V ~ 5.5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.8413","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/50583dbf408c178457ce0059a412707e.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM8AF6266UAY/alternatives.json"},"ai":{"faq":[{"question":"What is the core size of STM8AF6266UAY?","answer":"8-bit.
