It is not a high-speed motor-control engine; the real value is the deterministic interrupt response and the peripheral set that matches CAN and LIN bus nodes. The 2 KB EEPROM is handy for calibration constants and fault codes that survive a power cycle. ## Automotive bus interfaces — CAN and LIN onboard The STM8AF5288TAX integrates a CAN controller and a LIN/UART module, which are the two dominant physical layers in automotive body and comfort networks. If your design talks to a CAN bus or a LIN slave node, this MCU handles it without an external protocol chip. The 10-channel 10-bit ADC covers analog sensor inputs like potentiometers or temperature sensors. ## Package and supply — 48-LQFP, 3V to 5.5V The 3V to 5.5V supply range means it can run directly off an automotive battery rail (through a simple pre-regulator or even a series diode) without a dedicated 3.3V LDO, though the 5V logic levels need checking against any 3.3V peripherals on the same board. If your application sees sustained 105°C or 125°C junction temperatures, you need the extended-temperature variants in the STM8A family.","metaTitle":"STM8AF5288TAX 8-bit MCU, 24MHz, 64KB Flash, NRND","metaDescription":"STMicroelectronics STM8AF5288TAX 8-bit MCU, 24MHz core, 64KB Flash, 6K RAM, CAN/LIN, -40°C to 85°C.","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":"64KB (64K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"48-LQFP (7x7)","Voltage - Supply (Vcc/Vdd)":"3V ~ 5.5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.7817","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/a76a247b2d898b9b81fdf0b841467bbd.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM8AF5288TAX/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for STM8AF5288TAX?","answer":"STMicroelectronics has not published a single direct replacement order code.
