With 30 I/O lines and a 23-channel 12-bit ADC, this part can sample a bank of analog sensors — temperature, current, pressure — without an external multiplexer. ## Active lifecycle — no LTB planning needed The product status is Active. For a production BOM, this part can be qualified without building a bridge-head stockpile or qualifying a drop-in replacement.","metaTitle":"STM8L151K3U3TR STMicroelectronics 8-bit MCU, 16 MHz","metaDescription":"STM8L151K3U3TR 8-bit MCU from STM8L EnergyLite series. 16 MHz core, 8 KB Flash, 1 KB RAM, 256 B EEPROM, 23-ch 12-bit ADC, -40°C to 125°C.
