The surface-mount LQFP is rework-friendly with a standard hot-air profile — no hidden pads, no BGA alignment. Orientation is unambiguous: pin 1 mark is clearly molded. If you are swapping this in the field, a fine-tip iron and some flux will do the job, though a hot-air station makes removal cleaner. ## Lifecycle reality — obsolete, but findable Per the manufacturer, the STM8AL3166TAX is listed as Obsolete.","metaTitle":"ST STM8AL3166TAX 8-bit MCU, 16 MHz, 32 KB Flash, 32-LQFP","metaDescription":"STMicroelectronics STM8AL3166TAX 8-bit MCU with 16 MHz core, 32 KB Flash, 2K x 8 RAM, 1K x 8 EEPROM, 22x12b ADC, 1x12b DAC, -40°C to 85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"STMicroelectronics","Speed":"16MHz","Series":"STM8A","Package":"Tape & Reel (TR)","RAM Size":"2K x 8","Core Size":"8-Bit","EEPROM Size":"1K x 8","Peripherals":"Brown-out Detect/Reset, DMA, POR, PWM, WDT","Connectivity":"I²C, IrDA, LINbus, SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"30","Core Processor":"STM8","Package / Case":"32-LQFP","Product Status":"Obsolete","Data Converters":"A/D 22x12b; D/A 1x12b","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)","Supplier Device Package":"32-LQFP (7x7)","Voltage - Supply (Vcc/Vdd)":"1.65V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.0631","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/fcda9e9e20a5c37a9c561bb37d935f5e.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM8AL3166TAX/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM8AL3166TAX","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM8AL3166TAX when reusing this data.
