The STM8AL3188 (without the 'TAX' suffix) is the same base part number and shares the same core, memory map, and peripheral set — but the exact suffix difference may indicate package, temperature grade, or qualification variant. Without an official STMicroelectronics cross-reference document, the safest approach is to compare the full datasheet parametric tables for the STM8AL3188 variant against your BOM requirements. The 48-LQFP footprint, 16 MHz clock, 64 KB Flash, and AEC-Q100 rating are the anchor specs a replacement must match.","metaTitle":"STM8AL3188TAX 8-bit MCU, 64KB Flash, 16MHz, AEC-Q100","metaDescription":"STM8AL3188TAX is an obsolete 8-bit automotive MCU with 64KB Flash, 16MHz, 4Kx8 RAM, 2Kx8 EEPROM, 12-bit ADC/DAC, 48-LQFP.","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":"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":"41","Core Processor":"STM8","Package / Case":"48-LQFP","Product Status":"Obsolete","Data Converters":"A/D 25x12b; 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~85°C(TA)","Supplier Device Package":"48-LQFP (7x7)","Voltage - Supply (Vcc/Vdd)":"1.65V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.4600","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/0093a44ad742d68422bcf71762e1079a.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM8AL3188TAX/alternatives.json"},"ai":{"faq":[{"question":"Is STM8AL3188TAX obsolete?","answer":"Yes, the STM8AL3188TAX is listed as obsolete by STMicroelectronics.
