EFM8 Busy Bee Family

EFM8BB50 Data Sheet

The EFM8BB50, part of the wide supply 5 V Busy Bee family of

MCUs, is a multi-purpose line of 8-bit microcontrollers with a com-

prehensive 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 communication pe-

ripherals into small packages, making them ideal for space-constrained applications.

With an efficient 8051 core, 5 V capable I/O, precision analog, and enhanced pulse-width

modulation, the EFM8BB50 family is also optimal for embedded applications.

• Up to 12 multifunction, 5 V capable I/O

pins

• 1 x 12-bit Analog to Digital converter

• Integrated temperature sensor

• 3-channel PCA w/ PWM

• 3-channel PWM engine

• 4 x 16-bit timers

EFM8BB50 applications include the following:

• Appliances

• LED/Lighting control

• Toys

• Industrial automation

• 2 x 8-bit timers

• Personal hygiene products

• Consumer electronics

• UART

• Battery packs

• Motor control

• SMBus/I2C

• Optical modules

• Power tools

• SPI with 4 byte FIFO

• Priority crossbar for flexible pin mapping

• 4 x configurable logic units

• QFN packages as small as 2x2mm
