EFM8 Universal Bee Family
EFM8UB3 Data Sheet
The EFM8UB3, part of the Universal Bee family of MCUs, is a
multi-purpose line of 8-bit microcontrollers with USB feature set in
small packages. KEY FEATURES • Pipelined 8-bit C8051 core with 48 MHz
maximum operating frequency These devices offer high value by integrating an innovative energy-smart USB peripheral
interface, charger detect circuit, 8 kV ESD protection, and enhanced high speed communication interfaces into small packages, making them ideal for space-constrained USB
applications. With an efficient 8051 core and precision analog, the EFM8UB3 family is
also optimal for embedded applications. • Up to 17 multifunction I/O pins
• Low Energy USB with full-and low-speed
support saves up to 90% of the USB
energy
• USB charger detect circuit (USB-BCS 1.2
compliant) EFM8UB3 applications include the following: • One 12-bit ADC and two analog
comparators with internal voltage DAC as
reference input • Consumer electronics
• USB Type-C converters
• USB Type-C billboard/alternate mode • USB I/O controls
• Docking stations/USB hubs
• Dongles • Six 16-bit timers
• UART and SMBus master/slave
• Priority crossbar for flexible pin mapping Core / Memory Clock Management CIP-51 8051 Core
(48 MHz) Flash Memory …
