The 80-LQFP package gives you 68 I/O lines, plus a 28-channel 12-bit ADC and two 12-bit DACs — enough analog front-end to handle multiple sensor inputs without external muxes or signal-conditioning ICs. ## NRND — plan the last-time buy now That means STMicroelectronics is not accepting new design-ins, and volume availability will taper as the last-time-buy window closes. For an existing BOM that already qualifies this MCU, secure your final production run through a qualified independent distributor who can quote against an RFQ and confirm current availability. The 125°C upper limit covers engine-bay and brake-system modules; the -40°C low end handles cold-start in northern climates. If your design lives in a temperature-controlled cabinet, a commercial-grade STM8 variant may save cost, but for anything that sees the elements, this part is the right reliability tier.","metaTitle":"STM8AL318ATCY 8-bit MCU, AEC-Q100, 64KB Flash, 16 MHz","metaDescription":"STMicroelectronics STM8AL318ATCY 8-bit MCU, 16 MHz, 64KB Flash, 4K x 8 RAM, 2K x 8 EEPROM, -40°C to 125°C, AEC-Q100, NRND.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"NRND","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"STMicroelectronics","Speed":"16MHz","Series":"Automotive, AEC-Q100, STM8A","Package":"Tray","RAM Size":"4K x 8","Core Size":"8-Bit","EEPROM Size":"2K 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":"68","Core Processor":"STM8","Package / Case":"80-LQFP","Product Status":"Not For New Designs","Data Converters":"A/D 28x12b; D/A 2x12b","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~125°C(TA)","Supplier Device Package":"80-LQFP (14x14)","Voltage - Supply (Vcc/Vdd)":"1.65V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.5300","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/0093a44ad742d68422bcf71762e1079a.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM8AL318ATCY/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM8AL318ATCY","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM8AL318ATCY when reusing this data.
