SILICON LABS EFM8BB10F8I-A-QFN20R

The EFM8BB1, part of the Busy Bee family of MCUs, is a multipurpose line of 8-bit microcontrollers with a comprehensive feature set in small packages. These devices offer high-value by integrating advanced analog and communication peripherals into small packages, making them ideal for space-constrained applications. With an efficient 8051 core, enhanced pulse-width modulation, and precision analog, the EFM8BB1 family is also optimal for embedded applications.
