That means STMicroelectronics is not actively encouraging new designs to start with it, though it remains available for existing production programs through the independent distribution channel. For a new design, you will want to evaluate the official successor or a pin-compatible alternative within the STM8A family. ## Memory and peripheral fit for body/lighting modules The CAN interface (2.0B) and LIN controller cover the two dominant automotive buses, so a single part can serve as the gateway between a CAN backbone and LIN sub-nodes. ## Package and temperature — can I swap it on site? The 48-pin LQFP package is a common footprint, but it is not socketed — you will need a hot-air station or a reflow oven to replace it. The -40°C to 150°C rating means it lives under-hood or on an engine-mounted ECU without derating.","metaTitle":"STM8AF52A8TDY 8-bit MCU, 24MHz, AEC-Q100, 128KB Flash","metaDescription":"STM8AF52A8TDY 8-bit automotive MCU, 24MHz core, 128KB Flash, 6K RAM, 2K EEPROM, CAN/LIN, -40 to 150°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":"Automotive, AEC-Q100, STM8A","Package":"Tray","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~150°C(TA)","Voltage - Supply (Vcc/Vdd)":"3V ~ 5.5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$7.4100","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/a76a247b2d898b9b81fdf0b841467bbd.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM8AF52A8TDY/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy STM8AF52A8TDY and how do I get a price?","answer":"Submit an RFQ against this page to confirm current availability and pricing — we quote to order, so you get the real-time market number, not a stale list price."},{"question":"What is the equivalent for STM8AF52A8TDY?","answer":"Within the STM8A family, the STM8AF52A8TAY is a close sibling — it shares the same core, memory, and peripheral set but differs in the package variant. For a direct pin-compatible drop-in, check the STM8AF52A8x series in the same 48-LQFP footprint. For new designs, ST recommends moving to the STM8AF62xx or STM8AF72xx series, which offer higher performance and longer availability."},{"question":"What is the difference between STM8AF52A8TDY and STM8AF52A8TAY?","answer":"Both are 8-bit automotive MCUs with 128 KB Flash, 6 K RAM, 2 K EEPROM, CAN/LIN, and the same -40°C to 150°C rating. The difference is in the shipping medium and temperature grade suffix: the TDY variant comes in tray packaging, while the TAY variant is typically supplied in tape-and-reel. Functionally they are identical."},{"question":"Does STM8AF52A8TDY have a CAN interface?","answer":"This makes it suitable as a node on a vehicle's CAN bus or as a LIN master/slave."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM8AF52A8TDY","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM8AF52A8TDY when reusing this data.
