The 128 KB Flash is sized for control firmware with a CAN/LIN stack and a modest bootloader; the 2 KB EEPROM holds calibration constants and fault logs without external storage. The 24 MHz core clock delivers about 20 MIPS — enough for a real-time control loop at a few kHz with headroom for protocol handling. The 10-channel, 10-bit ADC covers analog sensor inputs like temperature or position feedback. ## Package and mounting — 48-LQFP footprint The STM8AF52A8TAX is supplied in a 48-lead LQFP package (0.5 mm pitch) for surface-mount assembly.","metaTitle":"ST STM8AF52A8TAX 8-bit MCU, 128KB Flash, 24MHz, 48-LQFP","metaDescription":"STM8AF52A8TAX 8-bit MCU from STMicroelectronics, 128KB Flash, 6KB RAM, 2KB EEPROM, 24MHz, CAN/LIN/SPI/I²C, -40°C to 85°C, 48-LQFP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"NRND","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"STMicroelectronics","Speed":"24MHz","Series":"STM8A","Package":"Tape & Reel (TR)","RAM Size":"6K x 8","Core Size":"8-Bit","EEPROM Size":"2K x 8","Peripherals":"Brown-out Detect/Reset, POR, PWM, WDT","Connectivity":"CANbus, I²C, LINbus, SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"38","Core Processor":"STM8A","Package / Case":"48-LQFP","Product Status":"Not For New Designs","Data Converters":"A/D 10x10b","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 ~ 85°C (TA)","Voltage - Supply (Vcc/Vdd)":"3V ~ 5.5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.1938","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/a76a247b2d898b9b81fdf0b841467bbd.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM8AF52A8TAX/alternatives.json"},"ai":{"faq":[{"question":"Is the STM8AF52A8TAX obsolete or still available?","answer":"It is still available for existing production but is not recommended for new project starts.
