The 32-LQFP package (7x7 mm) provides 29 I/O lines for board-level interfacing. ## NRND status — plan your last-time buy ST has flagged the STM8AL3L46TAY for phase-out, meaning it remains orderable for existing production runs but a last-time-buy window may be in effect. The STM8 core runs at 16 MHz. The 2 KB of RAM limits data buffer depth.","metaTitle":"ST STM8AL3L46TAY 8-bit MCU, 16 MHz, 16 KB Flash, 32-LQFP","metaDescription":"STMicroelectronics STM8AL3L46TAY 8-bit MCU, 16 MHz core, 16 KB Flash, 2 KB RAM, 1 KB EEPROM, 21x12b ADC, 1x12b DAC, -40°C to 85°C, 32-LQFP.
