Product Description

The EFM8BB2, 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 enhanced highspeed 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 EFM8BB2 family is also optimal for embedded applications.
