It carries 16 KB of Flash program memory, 2K x 8 of RAM, and 1K x 8 of EEPROM — enough for moderate control-loop firmware and non-volatile parameter storage. ## NRND — not for new designs, but still sourced for production runs That means ST is not actively promoting it for fresh BOMs, but it remains available for existing production lines through the independent channel. It provides 41 I/O lines in a 48-LQFP package (7x7 mm body).","metaTitle":"STM8AL3148TCY 8-bit MCU, 16 MHz, AEC-Q100, NRND","metaDescription":"ST STM8AL3148TCY 8-bit MCU, 16 MHz, 16 KB Flash, AEC-Q100 automotive grade, -40 to 125°C.
