EFM8 Universal Bee Family

EFM8UB3 Reference Manual

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.

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 commu-

nication 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.

EFM8UB3 applications include the following:

KEY FEATURES

• Pipelined 8-bit C8051 core with 48 MHz

maximum operating frequency

• 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)

• One 12-bit ADC and two analog

comparators with internal voltage DAC as

reference input

• Six 16-bit timers

• UART and SMBus master/slave

• Priority crossbar for flexible pin mapping

• USB I/O controls

• Docking stations/USB hubs

• Dongles

• Consumer electronics

• USB Type-C converters

• USB Type-C billboard/alternate mode
