Buyers should evaluate a pin-compatible replacement within the STM8A family for ongoing supply. With 16 KB of Flash and 2 KB of RAM, this MCU is sized for control firmware, not data-heavy applications. Typical firmware for a LIN-bus node, a brushless-DC motor controller, or a multi-sensor aggregator fits within 16 KB. The 1 KB EEPROM allows parameter storage (calibration constants, fault counters) without wearing the Flash. The 41 I/O lines in a 48-LQFP package give good pinout flexibility for mixed digital and analog signals. ## Connectivity and peripherals — LINbus, SPI, I²C, and more The LINbus support is key for automotive body electronics — door modules, seat controllers, and lighting nodes. The brown-out detect, POR, and watchdog peripherals improve system robustness in noisy environments. An internal oscillator reduces external BOM count, though a crystal can be added for tighter timing.","metaTitle":"ST STM8AL3148TAY 8-bit MCU, 16 MHz, 16 KB Flash, 48-LQFP","metaDescription":"STMicroelectronics STM8AL3148TAY 8-bit MCU, 16 MHz core, 16 KB Flash, 2 KB RAM, 1 KB EEPROM, 25-ch 12-bit ADC, 1-ch 12-bit DAC, -40°C to 85°C, 48-LQFP.","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":"STM8A","Package":"Tray","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":"STM8","Package / Case":"48-LQFP","Product Status":"Not For New Designs","Data Converters":"A/D 25x12b; D/A 1x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM8","Program Memory Size":"16KB (16K 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":"$2.0388","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/fcda9e9e20a5c37a9c561bb37d935f5e.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM8AL3148TAY/alternatives.json"},"ai":{"faq":[{"question":"Is STM8AL3148TAY obsolete?","answer":"It is not fully obsolete, but STMicroelectronics is phasing it out.
