The separate 2 KB EEPROM (not emulated Flash) stores calibration constants and fault logs without wear-leveling overhead — a real advantage over parts that require EEPROM emulation in Flash. ## CAN, LIN, I2C, UART — the connectivity set for automotive subnets Built-in CAN and LIN controllers let this MCU talk directly on vehicle body and powertrain buses without an external transceiver interface chip (though a transceiver is still needed for the physical layer). The I2C and UART ports handle local sensor and actuator links. With 25 I/O, it covers a typical mix of switch inputs, PWM outputs, and diagnostic lines.","metaTitle":"STM8AF52A6UCY 8-bit MCU, Automotive Grade, 24 MHz","metaDescription":"STMicroelectronics STM8AF52A6UCY 8-bit MCU, Automotive AEC-Q100, 24 MHz, 128 KB Flash, 6 KB RAM, 2 KB EEPROM, -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","Grade":"Automotive","Speed":"24MHz","Series":"STM8A","RAM Size":"6K x 8","Core Size":"8-Bit","Packaging":"Tray","EEPROM Size":"2K x 8","Part Status":"Not For New Designs","Peripherals":"Brown-out Detect/Reset, POR, PWM, WDT","Connectivity":"CANbus, I2C, LINbus, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"25","Qualification":"AEC-Q100","Core Processor":"STM8A","Package / Case":"32-UFQFN Exposed Pad","Data Converters":"A/D 6x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM8","Program Memory Size":"128KB (128K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 125°C (TA)","Supplier Device Package":"32-UFQFPN (5x5)","Voltage - Supply (Vcc/Vdd)":"3V ~ 5.5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.2600","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/a76a247b2d898b9b81fdf0b841467bbd.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM8AF52A6UCY/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM8AF52A6UCY","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM8AF52A6UCY when reusing this data.
