The Silicon Labs MCUs is a performance line of 8-bit microcontrollers with a comprehensive analog and digital feature set in small packages. It offer state-of-the-art performance by integrating 14-bit ADC, internal calibrated temperature sensor (±3 °C), and up to four 12-bit DACs into small packages, calibrated temperature sensor (±3 °C), and up to four 12-bit DACs into small packages, making them ideal for the most stringent analog requirement applications. With an efficient, pipelined 8051 core with maximum operating frequency at 72 MHz, various communication interfaces, and four channels of configurable logic, the EFM8LB1 family is optimal for many embedded applications.
