EFM8 Busy Bee Family
EFM8BB1 Data Sheet
The EFM8BB1, 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.
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, enhanced pulse-width modulation, and precision analog, the
EFM8BB1 family is also optimal for embedded applications.
EFM8BB1 applications include the following:
• Motor control
• Consumer electronics
• Sensor controllers
• Medical equipment
• Lighting systems
• I/O port expander
KEY FEATURES
• Pipelined 8-bit C8051 core with 25 MHz
maximum operating frequency
• Up to 18 multifunction, 5 V tolerant I/O pins
• One 12-bit Analog to Digital converter
(ADC)
• Two low-current analog comparators
• Integrated temperature sensor
• 3-channel enhanced PWM / PCA
• Four 16-bit timers
• UART, SPI and SMBus/I2C
• Priority crossbar for flexible pin mapping
