EFM8 Busy Bee Family
EFM8BB3 Data Sheet
The EFM8BB3, part of the Busy Bee family of MCUs, is a per-
formance line of 8-bit microcontrollers with a comprehensive ana-
log and digital feature set in small packages.
These devices offer state-of-the-art performance by integrating 12-bit ADC, internal
temperature sensor, and up to two 12-bit DACs into small packages, making them ideal
for general purpose applications. With an efficient, pipelined 8051 core with maximum
operating frequency at 50 MHz, various communication interfaces, and four channels
of configurable logic, the EFM8BB3 family is optimal for many embedded applications.
EFM8BB3 applications include the following:
• Consumer electronics
• Precision instrumentation
• Power management and control
• Industrial control and automation
• Smart sensors
KEY FEATURES
• Pipelined 8-bit 8051 MCU Core with
50 MHz operating frequency
• Up to 29 multifunction I/O pins
• One 12-bit/10-bit ADC
• Four 12-bit DACs with synchronization and
PWM capabilities
• Two low-current analog comparators with
built-in reference DACs
• Internal temperature sensor
• Internal 49 MHz and 24.5 MHz oscillators
accurate to ±2%
• Four channels of Configurable Logic
• 6-channel PWM / PCA
• Six 16-bit general-purpose timers
