The 48-LQFP package gives you 41 I/O lines, and the analog front end is generous: 25 channels of 12-bit ADC plus a single 12-bit DAC, so you can read a bank of sensors without bolting on an external converter. ## Peripherals that matter on a repair bench The internal oscillator means you can get it running without an external crystal, which simplifies a field swap when the original board's clock circuit is flaky. ST lists the STM8AL3168TAX as obsolete. For a repair or a legacy-board build, you are looking at the surplus and independent-distribution channel. ## Supply voltage and temperature — the field-fit check The 48-LQFP package with a 7x7 mm body is a standard footprint; you can hand-solder it in a pinch if the reflow oven is not an option, though the fine pitch calls for a steady hand and a decent magnifier.","metaTitle":"ST STM8AL3168TAX 8-bit MCU, 16 MHz, 32 KB Flash, 48-LQFP","metaDescription":"STMicroelectronics STM8AL3168TAX 8-bit MCU with 16 MHz core, 32 KB Flash, 2 KB RAM, 1 KB EEPROM, 25x12b ADC.","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":"41","Core Processor":"STM8A","Package / Case":"48-LQFP","Product Status":"Obsolete","Data Converters":"A/D 25x12b; 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":"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/fcda9e9e20a5c37a9c561bb37d935f5e.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM8AL3168TAX/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement or equivalent for STM8AL3168TAX?","answer":"ST does not publish a single direct-replacement order code for this part.
