The STM8AL3148TCX is listed as Not Recommended for New Designs (NRND). That means ST is not actively promoting it for new projects, though it may still be available for existing production runs through the independent channel. For a new design, the STM8A family has pin-compatible density options — look at the STM8AL3Lx or STM8AF52xx series for current automotive MCUs with similar peripheral sets. ## Automotive-grade peripherals and connectivity The MCU integrates 41 I/O lines, a 25-channel 12-bit ADC, a single 12-bit DAC, and a full set of automotive serial interfaces: I2C, SPI, UART/USART, LINbus, and IrDA. The LINbus interface is the typical choice for body-node communication in a vehicle. ## 48-LQFP package and supply range","metaTitle":"ST STM8AL3148TCX 8-bit MCU, 16 MHz, 16 KB Flash, AEC-Q100, 48-LQFP","metaDescription":"STM8AL3148TCX is an automotive-grade 8-bit MCU from STMicroelectronics, NRND. 16 MHz core, 16 KB Flash, 2 KB RAM, 1 KB EEPROM, 48-LQFP, -40 to 125°C.
