It has 64 KB Flash, 4 KB RAM, and 2 KB EEPROM. At 16 MHz the STM8 core executes most instructions in one or two clock cycles. The 64 KB Flash and 4 KB RAM support a single firmware image. ## Analog integration saves board space With 25 analog input channels on the 12-bit ADC and two 12-bit DAC outputs, this MCU can read a dozen temperature or pressure sensors and drive two analog actuators directly. The 48-LQFP package (7x7 mm) leaves room for the passives and protection diodes on a compact automotive PCB.","metaTitle":"ST STM8AL31E88TAY 8-bit MCU, 16 MHz, 64 KB Flash, AEC-Q100","metaDescription":"STM8AL31E88TAY 8-bit automotive MCU, 16 MHz, 64 KB Flash, 4 KB RAM, 2 KB EEPROM, 25x12b ADC, 2x12b DAC, 48-LQFP.
