It carries 8 KB of Flash program memory, 1 KB of RAM, and 256 bytes of EEPROM — enough for a single control loop, sensor hub firmware, or a simple communication stack. The 18-channel 12-bit ADC on a 28-pin UFQFPN package is dense; it lets you sample multiple analog inputs without an external multiplexer, which saves board space in multi-sensor acquisition designs. Supply range is 1.8 V to 3.6 V, which aligns with single-cell Li-ion or two-cell alkaline battery rails. Connectivity covers I²C, IrDA, SPI, and UART/USART — enough for a sensor node talking to a host controller over a serial bus. The STM8 core runs at 16 MHz.","metaTitle":"ST STM8L151G3U3 8-bit MCU, 16 MHz, 8 KB Flash, UFQFPN-28","metaDescription":"STMicroelectronics STM8L151G3U3 8-bit MCU, 16 MHz core, 8 KB Flash, 1 KB RAM, 256 B EEPROM, 18-ch 12-bit ADC, -40 to 125°C, UFQFPN-28.
