Product Description

The EFM8BB51, 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 pulsewidth modulation, the EFM8BB51 family is also optimal for embedded applications.
