SILICON LABS EFM8BB52F16I-C-QFN32

The EFM8BB52, part of the wide supply 5 Volt Busy Bee family of MCUs, is a multi - purpose 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, 5 Volt capable I/O, precision analog, and enhanced pulse - width modulation, the EFM8BB52 family is also optimal for embedded applications.
