EFM8BB50 Busy Bee 8-Bit MCUs

Silicon Labs EFM8BB50 Busy Bee 8-Bit MCUs are part of the wide supply 5V EFM8 family of MCUs. The Silicon Labs EFM8BB50 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 analogue and communication peripherals into small packages, making them ideal for space-constrained applications. With an efficient 8051 core, 5V capable I/O, precision analogue and enhanced pulse-width modulation, the EFM8BB50 family is also ideal for embedded applications.
