The 30 I/O lines in the 32-UFQFPN package give decent pinout flexibility for its footprint — you get a 12-bit ADC with 23 multiplexed channels, plus I2C, SPI, and UART connectivity. Brown-out detect, DMA, and a watchdog timer are integrated, so external supervisor ICs are optional in most designs.","metaTitle":"ST STM8L151K2U6 8-bit MCU, 16 MHz, 4KB Flash, 32-UFQFPN","metaDescription":"STMicroelectronics STM8L151K2U6 EnergyLite 8-bit MCU: 16MHz STM8 core, 4KB Flash, 1KB RAM, 256B EEPROM, 30 I/O, 1.8-3.6V, -40 to 85°C.
