EFM8 Busy Bee Family

EFM8BB2 Data Sheet

The EFM8BB2, part of the Busy Bee family of MCUs, is a multi-

purpose line of 8-bit microcontrollers with a comprehensive feature

set in small packages.

KEY FEATURES

• Pipelined 8-bit C8051 core with 50 MHz

maximum operating frequency

These devices offer high-value by integrating advanced analog and enhanced high-

speed communication peripherals into small packages, making them ideal for space-con-

strained applications. With an efficient 8051 core, enhanced pulse-width modulation, and

precision analog, the EFM8BB2 family is also optimal for embedded applications.

• Up to 22 multifunction, 5 V tolerant I/O

pins

• One 12-bit Analog to Digital converter

(ADC)

• Two Low-current analog comparators with

build-in DAC as reference input

EFM8BB2 applications include the following:

• Medical equipment

• Motor control

• Integrated temperature sensor

• Lighting systems

• Consumer electronics

• 3-channel PWM / PCA with special

hardware kill/safe state capability

• High-speed communication hub

• Sensor controllers

• Five 16-bit timers

• Two UARTs, SPI, SMBus/I2C master/

slave and I2C slave

• Priority crossbar for flexible pin mapping
