EFM8 BB5 8-bit Microcontrollers (MCUs)

The EFM8BB5, part of the wide supply voltage EFM8 family of MCUs, is a multi-purpose line of 8-bit microcontrollers with a comprehensive feature set in small packages. These devices offer advanced analog and communication peripherals in small packages, making them ideal for space-constrained applications. The pipelined 8051 core gives users a proven, high-performance 8-bit platform that is flexible enough to be used in a wide variety of applications. The BB50, BB51, and BB52 families of devices provide a flexible platform for even the most cost-conscious applications without the overhead of a 32-bit platform.
